Digital Outbound Marketing

Digital Marketing Communication Framework

Marketing communication has evolved into digital outbound marketing — the subset of promotion where a company initiates contact with target customers through digital channels. This contrasts with traditional broadcast (one-to-many) and with inbound (pull) or peer-to-peer (organic) communication. The framework below classifies communication types, maps the shift in advertising budgets, and introduces the MAP (Metrics, Accuracy, Privacy) lens for evaluating digital campaigns.

The Promotion Mix in the Value Delivery Process

The value delivery process has four stages: choose, provide, communicate, and sustain value. Communicate value (promotion) is where marketing communication sits. Within Integrated Marketing Communication (IMC) , digital is a subset. Companies allocate budgets across four broad channel categories:

Exam tip: Digital is a subset of IMC, but in practice it now captures the largest share of promotion budgets. Be ready to compare its advantages (targeting, interactivity, measurability) with traditional broadcast.

Shift in Advertising Spend: Traditional → Digital

From 2015 to 2019, total US ad spending grew from $183B to$240B (~33% growth). Digital grew from $59B to$130B — its share rose from ~33% to ~55%. Other channels stagnated or shrank:

Digital ad revenue is concentrated in a “trio‑poly”: Google (~26%), Facebook/Meta (~24%), and Amazon (~14–15%) together capture ~65% of US digital ad spend (2019–2023). Remaining 35% goes to other platforms (e.g., TikTok, LinkedIn, Snapchat).

Three Types of Digital Marketing Communication

Digital marketing communication can be classified by origin (who initiates) and organic vs. non‑organic:

• Outbound (push, non‑organic): Company creates ads and reaches target customers on digital platforms (search ads, social media ads, display banners). The focus of this module.
• Inbound (pull): Company attracts consumers to its own digital properties (website, blog, app) via useful content, search engine optimization, and social media presence. Consumers seek the brand.
• Social media (organic, peer‑to‑peer): Consumers amplify, share, or create content about the brand independently. The company has limited control.

Key distinction: A YouTube channel can be used for outbound (paid ads) or inbound (owned content). The same platform serves different communication modes.

The MAP Framework (Metrics, Accuracy, Privacy)

MAP is a lens for evaluating digital communication effectiveness and risks:

• Metrics – Constantly evolving measures of campaign performance (impressions, clicks, conversions, ROAS). The variety can be overwhelming; selection must align with campaign objectives.
• Accuracy – Enhanced by tracking user behavior, location, context, and social connections. More accurate targeting means more relevant ads, but also raises…
• Privacy – Consumers increasingly withhold data. Platforms like DuckDuckGo gain traction; Apple Safari/iOS provide privacy tools that limit tracking. Companies must balance targeting precision with consent and regulation.

Characteristics of Digital Marketing Communication

Every digital marketing communication (DMC) can be described by three dimensions:

1. Origin – Pull (consumer seeks), Push (firm drives), or Organic (peer‑to‑peer, typically on social media).
2. Trigger – The stage of the consumer decision journey the communication aims to influence (awareness, consideration, purchase, post‑purchase).
3. Outcome metrics – Evidence of success: clicks, conversions, engagement, ROI, etc.

These characteristics form the basis for campaign design and evaluation.

Key takeaways

• Promotion mix includes broadcast, direct response, BTL, and digital; digital now accounts for >50% of US ad spend.
• Digital communication has three types: outbound (push, paid), inbound (pull, owned), and social media (organic, peer‑to‑peer).
• The MAP framework highlights that better metrics and accuracy come with privacy trade‑offs.
• Marketers must align communication origin, trigger, and outcome metrics with the consumer decision journey.

Organic Search

Organic search refers to the natural, unpaid ranking of web pages on a search engine results page (SERP). The ranking is determined by the search engine’s algorithm (e.g., Google’s PageRank algorithm) and is relatively unbiased — it depends on the relevance and quality of the page’s content, not on payment. Brands invest in search engine optimization (SEO) to improve their organic ranking.

• On a typical SERP, 3–4 sponsored ads appear at the top, followed by ~10 organic results.
• The vast majority of users never go beyond the first page. Being on page 2 or later is effectively invisible.

Exam tip: Organic ranking is driven by the PageRank algorithm (link structure and content relevance). It is not influenced by bidding — that is the domain of paid search.

Paid Search Advertising

Paid search advertising (search ads) allows advertisers to pay the search engine to display ads in response to specific keywords. Ad ranking is based on:

1. Bid – the maximum amount the advertiser is willing to pay per click.
2. Ad quality – relevance of the ad copy to the keyword, landing page quality, and the expected click-through rate (probability the ad will be clicked).

The underlying auction mechanism (explained by Hal Varian, Google’s chief economist) ensures that a combination of bid and quality determines ad placement.

The 6Ms Framework for Campaign Planning

Any digital marketing campaign (including search) should be structured using the 6Ms framework:

• The mission must be specific, measurable, and time-bound.
• For B2B campaigns, the target audience may involve multiple roles within the decision-making unit; the message and media must be tailored accordingly.

---

Integrated Marketing Communications (IMC) Framework

The IMC framework combines two models to link channels with the consumer decision journey:

Bottom‑up Communications Matching Model

This model matches each stage of the consumer decision journey with the communication objectives appropriate at that stage.

Stages of the consumer decision journey (adapted from Batra & Keller):

1. Need recognition
2. Awareness/Knowledge
3. Consideration / Search for information
4. Trust / Liking
5. Willingness to pay (value perception)
6. Commitment / Purchase
7. Consumption / Satisfaction
8. Loyalty (repeat purchase)
9. Engagement (interaction, sharing)
10. Advocacy (positive word‑of‑mouth)

At each stage the consumer may reject the option and restart the process (non‑linear).

Top‑down Communication Optimization Model

This model identifies all communication platforms/channels available:

• Advertising (mass media, digital)
• Sales promotion
• Events & experiences
• PR & publicity
• Online & social media marketing
• Mobile marketing
• Direct & database marketing
• Personal selling

Linking the Two Models

The effectiveness of an IMC program depends on selecting the right channel(s) for the desired outcome at each decision stage. Possible communication outcomes include:

Factors Affecting Consumer Communication Processing

The consumer’s ability to process and be influenced by a communication depends on:

• Consumer characteristics – Motivation (need‑driven), Ability (knowledge/education), Opportunity (time, distraction) – collectively MAO.
• Situational factors – Time, place, context of exposure.
• Communication characteristics:
  • Modality – text, audio, video, animation, channel.
  • Source – commercial vs. personal credibility.
  • Executional features – creative style, tone, format.
  • Brand/product information – complexity, uniqueness.

All these factors interact to determine which outcome(s) the communication achieves.

---

Key takeaways

• Organic search is algorithm‑driven (unpaid); paid search combines bid with quality score (ad relevance + landing page + expected CTR).
• The 6Ms framework (Mission, Market, Message, Media, Money, Metrics) provides a structured approach to campaign planning.
• IMC requires matching communication platforms (top‑down) to the stages of the consumer decision journey (bottom‑up) for a given outcome (awareness, trust, action, etc.).
• Consumer processing is governed by MAO (Motivation, Ability, Opportunity), situational factors, and communication characteristics.
• The decision journey and outcome list are presented as a general framework, without numerical estimates.

Digital Marketing Framework & POEM

A digital marketing framework integrates inputs, channels, analysis, and measurement. The core channel classification is POEM: Paid, Owned, and Earned media.

The Framework in Brief

• Inputs come from digital marketing analytics: consumer needs, segment characteristics, personas, competitor data, public census/sector data.
• POEM represents the three media types.
• Measurement models assess effectiveness and efficiency. Common models are market mix models (MMM) which isolate the impact of each marketing-mix element (product, price, promotion, place) across omnichannel campaigns.
• The process is iterative: ask research questions, run campaigns, analyse, optimise.

POEM – Paid, Owned, Earned

Paid Media – Key Concepts

• Auction of ad space in real time; brands pay per click (PPC) or per impression.
• Payment models:
  • CPM (Cost Per Mille – cost per thousand impressions)
  • CPC (Cost Per Click)
  • CPA (Cost Per Acquisition – e.g., form fill, purchase)

Main Categories of Paid Media

Analytics Types for Paid Media

Paid Media Metrics & Dimensions

Core Metrics

• Impressions – number of times an ad is shown.
• Clicks – number of times an ad is clicked.
• Conversions – a desired action defined by the marketer (purchase, sign-up, download, form submission, phone call).
• Revenue – money generated from conversions.
• Cost – total spend on ads.

Exam tip: Conversions are not always purchases – they can be any valuable action (e.g., eligibility check, newsletter sign-up). Always check the definition.

Derived Metrics

$\text{CTR} = \frac{\text{Clicks}}{\text{Impressions}}$ $\text{CPC} = \frac{\text{Cost}}{\text{Clicks}}$

Key Dimensions for Analysis

• Location data is opt-in; many users share only when necessary.
• In-market segments are inferred from search and content interactions (e.g., someone researching insurance).
• Interests are mapped from browsing and social behaviour.

Example: Google Ads Report (Ad Group Level)

Key takeaways

• The digital marketing framework integrates inputs, POEM, analysis, and measurement models (e.g., MMM).
• POEM = Paid, Owned, Earned – each with distinct characteristics.
• Paid media includes search, display, social, affiliate, and e-commerce ads; payment can be PPC, CPM, or CPA.
• Core metrics: impressions, clicks, conversions, revenue, cost; derived: CTR, CPC.
• Dimensions (behavior, audience, technology) allow granular segmentation – always consider the privacy opt-in nature of location and demographic data.

KPIs and Native Ads

Key performance indicators (KPIs) quantify paid media’s impact on business outcomes. Commonly tracked: cost per click (CPC) and cost per conversion. Firms also compute return on investment (ROI) and return on ad spend (ROAS). When interpreting ROAS, note that revenue is not the same as profit — true return should account for margin after expenses.

Communication objectives align with the three components of attitude:

• Cognitive – what customers think about the brand.
• Affective – what they feel (positive emotions, predispositions).
• Conative – what they do (intention to buy, actual purchase).

Every campaign ultimately performs a cost‑benefit analysis: what benefit was achieved relative to spend.

The TCR Framework

Any digital property (website, social handle) has three broad objectives:

A common funnel: Impressions → Clicks → Traffic → Engagement (bounce rate, time on site) → Conversion → Revenue. Each step can be tracked online, making paid media highly measurable.

Paid, Owned, and Earned Media

Paid media billing models include:

• CPM (cost per mille) – pay per 1,000 impressions.
• CPC – pay per click.
• CPA – pay per conversion.

Reach = number of unique users exposed. Impressions = total times an ad is shown (can exceed reach if same user sees it multiple times). Example: reach of 1 million with 2.5 million impressions → average frequency = 2.5.

Key takeaways – KPIs & Media Types

• KPIs track cost per click, per conversion, ROI, and ROAS – always separate revenue from margin.
• Attitudes span think (cognitive), feel (affective), do (conative).
• The TCR funnel: Traffic → Conversion → Revenue.
• Paid media uses impression‑ or action‑based pricing; owned and earned media differ in control and cost.

---

Native Advertising

Native advertising is sponsored content designed to blend into the surrounding editorial or organic content. On digital platforms it appears as in‑feed ads, recommended content, or promoted listings. The ad’s look and feel matches the publisher’s style; a small label (e.g., “Sponsored”) identifies it.

• Example 1: A workout article with a native ad titled “Try this 9‑minute workout – burn 300+ calories.” Clicking leads to a landing page for the “8fit” app.
• Example 2: Grammarly – “Great writing, simplified.” Uses a video format showing the tool’s benefit before the click, ensuring only interested users reach the landing page.

Native ads allow A/B testing of imagery, headlines, and campaign content to increase conversions.

---

Affiliate Marketing

Affiliate marketing is a performance‑based strategy: the merchant rewards external partners (affiliates) for driving traffic or sales. Three entities interact:

• Merchant (e.g., an online store) provides the product/service.
• Affiliate (publisher) – a website, blog, social media influencer, or media channel (e.g., NDTV.com) – places links or ads.
• User clicks the affiliate’s link and completes a purchase → merchant pays the affiliate a commission.

Affiliates often use multiple channels: websites, blogs, social media, email. This creates a mutually beneficial relationship: the firm gains exposure and sales, the affiliate earns a commission.

Key takeaways – Native Ads & Affiliates

• Native ads mimic editorial content; identified by a “Sponsored” tag.
• Affiliate marketing has three parties: merchant, affiliate (publisher), user.
• Affiliate earns commission per sale or lead; merchant pays only for performance.

---

Search Engine Marketing (SEM)

Users search with keywords. The search engine results page (SERP) displays both paid ads (sponsored links) and organic results. Example: searching “five star hotels near Mumbai Airport” returned ~30 million results in 0.74 seconds. Top results were ads (ITC Grand Central, Taj, etc.) followed by organic links (MakeMyTrip).

Organic vs. Paid

Ranking behavior: Most users click the top 3 organic links; click‑through drops sharply for positions 4–10. The same pattern holds for sponsored links.

Generic vs. Branded Keywords

• Generic keywords capture users with broad intent; they explore, compare, and have low conversion.
• Branded keywords target users who have already decided on a brand; they simply need a link to book. Consequently, branded keywords have much higher CTR and conversion rates, implying a lower cost per sale.

Bidding strategy: Firms can bid on both generic and branded terms. Since payment is per click, branded terms are often more efficient. The suggested bid amount is a starting point; experimentation is common.

Key takeaways – Search Marketing

• SERP mixes paid ads and organic results; top 3 links receive the majority of clicks.
• Generic keywords (e.g., “hotels in Mumbai”) yield low CTR (~0.3%) and low conversion → high cost per sale.
• Branded keywords (e.g., “Novotel Mumbai”) yield high CTR (~15%) and high conversion (~6%) → low cost per sale.
• Bidding on one’s own brand name is often worthwhile because users are already pre‑committed.

Exam tip: The distinction between generic and branded keywords is a classic test point – remember the specific metrics (CTR 0.3% vs. 15%; conversion 6% for branded) to illustrate why branded keywords are more cost‑effective.

Keywords, Bidding, and Auctions

When running a paid search campaign, three decisions dominate: which keywords to bid on, how much to bid per click, and how to design the ad and landing page. The underlying mechanism is the generalized second‑price auction (GSP), where advertisers bid for ad positions and pay the minimum needed to keep their position — typically less than their actual bid, and based on the bid of the competitor below them.

Keyword Selection & Bidding

• Keyword tools (e.g., Google Ads Keyword Planner) provide competitor keywords, suggested bids, and competitiveness indicators.
• Match types – exact match (e.g., “running shoes for athletes”) vs. broad match (“running shoes”) let you control specificity.
• Budget control – set daily, hourly, weekly, or monthly caps; you never spend more than your limit.
• Ad copy & landing page – the chosen keywords should appear in the ad text and link to a relevant, high‑quality landing page.
• Geotargeting, language, time – restrict ads to specific locations, languages, or time windows (e.g., evenings, weekends, only Tuesday afternoons).

Auction Mechanism & Quality Score

Ad position is determined by bid amount × quality score (a composite of predicted CTR, landing page relevance, and other factors). The search engine balances:

• User experience – relevant, helpful results.
• Advertiser needs – high visibility for relevant ads.
• Search engine revenue – profit from the auction.

Exam tip: Bidding highest does not guarantee top position — a lower bid with a high quality score can outrank a higher bid with poor quality.

You pay the minimum necessary to keep your position, which is the bid of the advertiser just below you (GSP rule). The exact formula is proprietary, but the principle ensures you never pay more than your bid.

Key Metrics & ROI Calculations

Worked Example 1: Display Ad (Google)

$$\begin{aligned} \text{CPM} &= \frac{181\ 159}{98\ 000\ 000} \times 1\ 000 = 1.84 \quad (\$1.84) \\[4pt] \text{CTR} &= \frac{29\ 537}{98\ 000\ 000} \times 100 = 0.03\% \\[4pt] \text{Conversion rate (TCR)} &= \frac{1\ 347}{29\ 537} \times 100 = 4.56\% \\[4pt] \text{Total margin} &= 1\ 347 \times 500 = 673\ 500 \\[4pt] \text{ROAS} &= \frac{673\ 500 - 181\ 159}{181\ 159} \times 100 = 271\% \end{aligned}$$

For every dollar spent on display, $2.71 in margin was generated.

Worked Example 2: Search Ad (Google)

$$\begin{aligned} \text{CTR} &= \frac{72\ 894}{1\ 800\ 000} \times 100 = 4.04\% \\[4pt] \text{CPC} &= \frac{123\ 000}{72\ 894} = 1.69 \\[4pt] \text{Conversion rate} &= \frac{788}{72\ 894} \times 100 = 1.08\% \\[4pt] \text{Net revenue} &= 788 \times 1\ 000 - 123\ 000 = 665\ 000 \\[4pt] \text{ROAS} &= \frac{665\ 000}{123\ 000} \times 100 = 540\% \end{aligned}$$

Every dollar invested in search generated $5.40 in net revenue.

Exam tip: When calculating ROAS, distinguish between gross revenue and net revenue (margin) – the numerator must match the definition used in the exam.

Display Ads – Characteristics & History

Display ads appear when users are not actively searching – while reading news, watching videos, etc.

• Origins – The first banner ad sold by Hotwired (1994) on a CPM basis. P&G later negotiated a CPC deal with Yahoo (1996).
• Click‑through rates average below 0.1% – less than one click per thousand impressions (worse odds than being struck by lightning).
• Targeting – ads can be matched to site content or user profiles, but often become obtrusive (pop‑ups, auto‑play video).
• Payment model – CPM (impressions), CPC (clicks), or CPA (cost per action/purchase). Paying on results (CPC or CPA) reduces advertiser risk.

Customer Journey & Communication Objectives

Successful campaigns map ad objectives to stages of the customer journey:

• Pre‑trial stages: awareness → learning → consideration.
• Post‑trial: purchase → use → return / repeat / advocacy.
• Showrooming: experience in‑store, then buy online (for better price or choices).
• Webrooming: research online, then buy in‑store (touch‑and‑feel products like furniture, apparel).

Marketing influences consumers across increasingly numerous touchpoints – social media, review sites, blogs, in‑person discussions. The key is to define a specific, actionable objective at each stage (e.g., “increase rate of engaged customers who try the product”) rather than a vague “increase sales”.

Exam tip: Align campaign type (search, display, email) with the customer journey stage it targets – search excels at capturing intent (consideration/purchase), display builds awareness and retargets.

Key takeaways

• Keyword selection uses tools; bidding is a GSP auction where you pay the minimum to keep your position, not your actual bid.
• Quality score (predicted CTR, landing page relevance) balances high bids with user experience.
• Core metrics: CPM, CTR, CPC, conversion rate, and ROAS – use consistent numerator definitions.
• Display ads have very low CTRs but are effective for reach; payment models shift risk to the advertiser.
• Communication objectives must be tied to specific customer journey stages – awareness, consideration, purchase, post‑purchase advocacy.
• Showrooming vs. webrooming – understand how consumers switch between online and offline channels.

Choosing the Right Digital Media

Selecting the right digital medium for outbound marketing is guided by three core criteria drawn from the Six M framework (Mission, Market, Media, Message, Money, Measurement). The decision process narrows options iteratively, from high-level objectives to granular budget optimisation.

Three Decision Criteria

1. Mission & Market – Define the campaign objective and the target audience. Be specific about where in the customer journey you want to intervene and on whom.
2. Media & Message – Choose the media platform and the content/message format that best express the campaign. Focus on effectiveness: “doing the right things” to achieve the objective for the given market. Use experimentation (e.g., A/B tests, test & control) to assess effectiveness continuously – daily or even hourly – before committing large budgets.
3. Money & Efficiency – Determine the optimal spend across available media/vehicle options. Focus on efficiency: “how best to do it” given a fixed budget, comparing alternatives to maximise achievement of objectives.

These criteria map onto the Six M framework as follows:

From Objectives to KPIs to Campaign Settings

A business defines high-level objectives and key performance indicators (KPIs). For communication, these are translated into advertising objectives, which in turn determine:

• Audience – who to target.
• Creative – how the message is conveyed.
• Bid amount – for each keyword or placement.
• Budget – total spend for the campaign.

These parameters are set and then continuously measured against campaign-specific objectives.

Exam tip: The distinction between effectiveness (doing the right things – mission, market, media, message) and efficiency (doing things right – money) is a frequently tested trade-off. A/B testing tests effectiveness; budget allocation tests efficiency.

Facebook Ads Manager as an Example

Facebook Ads Manager provides tools to create ads, manage multiple campaigns, and evaluate ad performance. It embodies the entire decision process:

• Define objective (e.g., brand awareness, conversions).
• Select audience (market).
• Choose creative (message) and placement (media).
• Set bid and budget (money).
• Measure results (measurement).

Marketers use this tool to iterate rapidly.

Key Takeaways

• Three decision criteria: (1) Mission & Market, (2) Media & Message (effectiveness), (3) Money & Efficiency.
• Effectiveness is about choosing the right media/message for the objective; efficiency is about spending the limited budget optimally.
• Continuous A/B testing and test-and-control experiments assess effectiveness before large spend.
• Campaign settings include audience, creative, bid, and budget – all tied to advertising KPIs derived from business objectives.
• Facebook Ads Manager is a concrete platform where these criteria are operationalised.

Mapping the Customer Journey to Facebook Ads Objectives

The customer journey — Awareness → Consideration → Conversion — is directly reflected in Facebook Ads Manager’s marketing objectives. Each objective corresponds to a stage of the sales funnel and the type of action you want the user to take.

Sales funnel logic:

• Awareness activities are broad, top-of-funnel.
• Consideration activities (e.g., app installs) are mid-funnel indicators of interest.
• Conversion activities target users ready to buy – happens on your website, Facebook page, or in-store.

Exam tip: Always match your campaign objective to the funnel stage. For example, a D2C mattress brand uses brand awareness (top) for new customers, then conversion (bottom) with retargeting for users who already engaged.

Key takeaways

• Facebook’s three objective categories mirror the customer journey: Awareness, Consideration, Conversion.
• The same metric (e.g., app installs) can be Consideration in one context and Conversion in another – depend on the business model.
• D2C companies often push for conversion after building awareness.
• Offline conversion (store visits) is a legitimate Facebook conversion objective.

---

Targeting & Audience Tools

Facebook provides three audience types to reach the right people.

Strategy spectrum

• Broad (Core): rely on platform algorithms, exclude already-converted customers. Aim: reach new users.
• Narrow (Custom/Lookalike): tight targeting for retargeting and conversion campaigns. Use layered options (e.g., past website visitors + interests).
• For D2C: start with broad core audiences for awareness, then switch to custom/lookalike for conversion retargeting (bottom-of-funnel).

---

Geofencing

Geofencing targets users within a defined geographic radius – they see ads on mobile even without app download.

• Food court example: restaurant shows ads to people inside the mall (100m radius).
• Retail chains: if a customer has the store’s app, notifications can trigger near a specific aisle.
• Without app: simply target device location.
• Follow-up: if user engages with the ad, retarget them online to encourage an offline store visit.

Common for categories where customers want to touch/feel before buying (mattresses, fans, apparel, paints).

---

Creative Options: Placement & Ad Formats

Placement – where your ad appears.

• Automatic placements (recommended for startups): Meta’s delivery system allocates budget across Facebook, Instagram, Messenger, Audience Network to maximize performance.
• Manual: you choose specific placements. More placements = more reach opportunities.

Ad format – how the ad looks.

• Carousel: two or more scrolling images/videos.
• Single image or video.
• Collection: group of items that opens into a full-screen mobile experience.

---

Bid & Budget Controls

How the ad auction works: Total value = (Advertiser value: bid × estimated action rates) + (Consumer experience: relevance). The platform maximises total value – it does not always show the highest bid. It balances relevance.

---

Measuring Campaign Impact

Two broad methods:

1. Experimental Methods (A/B Testing)

• Control group (not shown the ad) vs test group (exposed).
• If test group sales are higher (all else equal), the ad caused the lift.
• Result: a bar chart comparing sales – higher bar = better impact.

2. Observational Methods

Exam trap: Last-click attribution is the simplest but often leads to wrong budget decisions – you might cut Facebook and Instagram budgets when they actually drove the initial interest.

Attribution example: User journey: Facebook ad → search for “energy efficient fan” → Instagram ad → display ad (clicked) → conversion.

• Under last-click, display gets 100% credit.
• In reality, earlier touchpoints (Facebook, Instagram) influenced the decision.
• If conversion happens offline (store visit) after seeing a display ad, the chain breaks and you lose measurement unless you survey customers.

---

Key Takeaways

• Match campaign objective to funnel stage (Awareness → Consideration → Conversion).
• Use core audiences for broad reach; custom and lookalike for retargeting and conversion.
• Geofencing bridges online ads and offline store visits.
• Automatic placement is recommended to start; bid strategies balance cost and delivery.
• A/B testing (experimental) proves causality; attribution and MMM (observational) estimate influence.
• Last-click attribution is dangerously simplistic – always consider the full touchpoint journey.

Attribution Models

Attribution models assign credit for a conversion (e.g., a sale) to the marketing channels or touchpoints that influenced the customer along their journey. When campaigns run across multiple channels — Facebook ads, email, organic search, display, direct traffic, referrals — a brand manager needs to know which channels actually drove the sale in order to reallocate budget and optimise campaigns.

Why attribution matters

• Identifies which channels create awareness (top of funnel) and which close the sale (bottom of funnel).
• Guides decisions: shift budget away from underperforming channels toward the ones generating the most revenue.
• Links directly to the customer journey: awareness → consideration → intent (assist) → decision (last interaction).

---

Rule-Based Attribution Models

These models apply a fixed, heuristic rule to distribute credit.

How each model works (with the same journey)

Assume a customer’s path: Facebook Ad → Email → Organic Search → Display → Direct → purchases for $100.

• First Click → Facebook gets $100 (triggered awareness).
• Last Click → Direct gets $100 (closed the deal).
• Last Non-Direct Click → If Direct is the last click, credit goes to the previous non-direct touchpoint — in this path, Display gets $100.
• Linear → Each of the 5 channels gets $20.
• Position-Based → First (Facebook) $40, Last (Direct)$40, the remaining three (Email, Organic, Display) split $20 =$6.67 each.
• Time Decay → Channels closer to conversion get more credit. Assuming order: Display (first) → Email → Facebook → Organic → Direct (last). Then: Display $5, Email$10, Facebook $15, Organic$30, Direct $40.
• Last AdWords Click → Only matters if one of the touchpoints is a paid AdWords click; otherwise irrelevant.

Exam tip: First-click is best for measuring awareness; last-click for conversion. Time-decay offers a middle ground, while linear is fair but can dilute credit across low-impact channels. Position-based is common when you care equally about opening and closing the funnel.

---

Data-Driven Attribution

Data-driven (algorithmic) models use statistical techniques — typically variants of regression analysis — to assign credit based on the actual effectiveness of each channel in driving conversions. They are unbiased by arbitrary rules: “you plug in your end goals and weight each channel based on its effectiveness.”

• No heuristic; the data determines the share of credit.
• Requires sufficient historical data and technical resources.
• The conversion (dependent variable) is modelled as a function of channel interactions.

When to use: when you have the data, time, and analytical capability to let the numbers speak without human assumptions.

---

Custom Attribution

Platforms (e.g., Google Analytics) allow marketers to create their own rules — assign credit based on position, type of interaction, traffic source, campaign, keywords, etc. This is useful when a standard model does not reflect your specific business logic.

---

Choosing an attribution model

Key takeaways

• Attribution models solve the “which channel gets credit?” problem in multi‑channel campaigns.
• Rule-based models are simple and data‑light: first click, last click, last non‑direct click, linear, position‑based, time decay, last AdWords click.
• Data-driven models use statistical algorithms to assign credit without bias, but require more data.
• The choice depends on business goals (awareness vs. conversion) and data maturity.
• No single model is universally “best” — start with a simple rule-based model and evolve toward data-driven as data accumulates.

Search Ads – Cost per Click

Cost per Click (CPC) is the amount an advertiser bids on a specific keyword. When a user clicks the displayed ad, the advertiser pays — but only then. Intuitively: you pay for attention, not for showing up. The challenge: how much to bid, and how to ensure you actually appear in front of the right users.

How Search Engines Decide Which Ad to Show

Search engines don’t simply take the highest bidder. They run a Generalized Second Price (GSP) Auction — a Nobel Prize–winning idea (William Vickrey). In this auction:

• The highest bidder wins the first ad position.
• But pays the bid of the second‑highest bidder.
• The second position pays the third‑highest bid, and so on.

This encourages truth‑telling: advertisers bid their true willingness to pay, because paying less than your bid means you won’t overpay.

Exam tip: GSP auction ensures that no advertiser pays more than their maximum bid – and usually pays less. This is a key source of cost certainty.

Why Add a Quality Score?

If only bid amount mattered, a large budget could push irrelevant ads to the top, annoying users and driving them to other search engines. To balance the needs of user, advertiser, and search engine, Google assigns a Quality Score (1–10) to each ad. This score is based on:

1. Expected click‑through rate (CTR) – how likely users are to click.
2. Ad relevance – how closely the ad matches the search query.
3. Landing page quality – measured by bounce rate and consistency with the ad.

The Ad Rank = Bid × Quality Score. Higher rank wins a better position. Even a low bidder can reach the top if their quality score is high.

The Full Auction: Worked Example

Four advertisers bid for the keyword “running shoes”:

Only 3 ad slots are available. Ad Rank (descending order):

1. Y (12)
2. X (9)
3. Z (8)
4. W (4) – not shown.

Now compute actual CPC each advertiser pays. For the first‑ranked advertiser (Y):

$$P_1 = \frac{B_2 \times Q_2}{Q_1} = \frac{3 \times 3}{6} = \frac{9}{6} = \$1.50$$

Where:

• $B_2 = 3$ (bid of second‑rank X)
• $Q_2 = 3$ (quality score of X)
• $Q_1 = 6$ (quality score of Y)

Similarly for second‑rank (X):

$$P_2 = \frac{B_3 \times Q_3}{Q_2} = \frac{1 \times 8}{3} = \frac{8}{3} \approx \$2.67$$

For third‑rank (Z):

$$P_3 = \frac{B_4 \times Q_4}{Q_3} = \frac{4 \times 1}{8} = \frac{4}{8} = \$0.50$$

Observation: Y bid $2, but pays only$1.50. Z bid $1, pays$0.50. And W, despite bidding $4, never shows — because its quality score is too low.

The Auction Process Visualised

Key Takeaways

• CPC = cost per click; advertisers pay only when a user clicks.
• Generalized Second Price auction means top position pays the second‑highest bid — encourages honest bidding.
• Quality Score (1–10) ranks ads on expected CTR, relevance, and landing page quality; it can make a lower bidder win.
• Actual CPC = (next lower rank’s bid × their quality score) / (your quality score). Always ≤ your maximum bid.
• High quality score lowers your CPC — focus on ad relevance and landing page experience.
• Advertisers never know exact cost in advance, but it will never exceed the budgeted maximum bid.

Measuring Ad Effectiveness

Measuring ad effectiveness means quantifying the return on marketing investment (ROMI) — especially when a firm operates both online and offline channels. The central challenge is that advertising in one channel can influence sales in another, making simple attribution misleading.

Why This Is Hard: Key Measurement Challenges

• Endogeneity — ad spend is not random; it's correlated with unobserved demand shocks (e.g., a brand spends more when sales are already dropping).
• Dynamic effects — the impact of an ad changes over time (wear-in, wear-out, seasonality).
• Multivariate dependent variables — sales are not a single number; there are online sales, offline sales, and intermediate metrics (impressions, clicks).
• Autocorrelation — independent variables (e.g., ad spend across weeks) are correlated with themselves over time.
• Competitor advertising — a competitor's campaign affects your results but is usually unobserved in your model.

Exam tip: Any exam question on measuring effectiveness will likely test your awareness that cross-channel effects exist and ignoring them biases ROI calculations.

Cross-Channel Effects: Evidence from an Apparel Retailer

A 2014 study on a US high-end apparel retailer (similar to Shoppers Stop / Zara) with 85% offline revenue and 15% online revenue modelled the interplay of traditional (TV, print) and online (display, paid search) advertising.

Model structure:

• Traditional ads → offline sales and online sales.
• Online display + search ads → online sales and offline sales.
• All effects operate through intermediate metrics like impressions and click-through rates (CTR).

Key findings:

Lesson: Attribution models that ignore offline‑to‑online and online‑to‑offline cross effects miscalculate ROMI.

---

Long-Term Health: CAC and LTV

• Customer acquisition cost (CAC) and customer lifetime value (LTV) must be tracked over time to avoid overspending on short-lived customers.
• Tracking frequency depends on category: department stores → monthly/quarterly; FMCG/grocery → weekly.
• Intermediate metrics (impressions, CTR) are short-term; prefer average CAC over the entire campaign period instead of per-channel CAC.
• A/B testing is the gold standard but requires careful design and continuous iteration.
• Long-term success depends on a sustainable brand and customer value proposition, not just campaign-level tactics.

Multi-Stage Attribution: The Hidden Markov Model (HMM)

A second study used a Hidden Markov Model to map the consumer journey through latent states:

• $q_{ss'}$ = transition probability from state $s$ to $s'$.
• $y_s$ = observed variables (e.g., ad exposures, clicks) emitted in each state.

Findings:

Exam tip: Display ads are not useless — they work at the top of the funnel, while search works throughout. Multi‑state models reveal this whereas single‑touch attribution hides it.

Worked Example: Bank Account Acquisition Funnel

A bank runs online ads, offline ads (TV, billboard, radio), and branch campaigns. The true sales outcome depends on cross-channel interactions:

Ignoring $\beta_1, \beta_2, \theta_1, \theta_2$ misattributes credit.

Online funnel stages (hypothetical numbers):

The real goal is not clicks but long‑term active customers.

Practical Takeaways for Managers

• Online advertising is easier to measure — temptation is to shift budgets to digital. But offline advertising builds brand awareness and trust, especially for products sold through retail.
• D2C startups often start online-only but must eventually add offline channels to scale (e.g., Nykaa, Atomberg). Ignoring offline cross-effects leads to underinvestment in brand building.
• Cross-channel complementarity makes it hard to disentangle exact channel impact. Use continuous A/B tests and average CAC over longer windows.
• Never rely solely on last-click attribution — it ignores top-of-funnel display effects and offline‑online interactions.

Key takeaways

• Cross-effect elasticities between online and offline channels are nearly as large as own-effect elasticities.
• Display ads drive early stages; search ads drive later stages — both are needed.
• CAC and LTV must be tracked over time; short‑term metrics (CPM, CTR) can mislead.
• Multi‑state attribution (HMM) provides more accurate ad effectiveness than rule-based models.
• Offline advertising is critical for brand building even when online is easier to measure.

Atomberg Example: Digital Outbound Marketing in Practice

Atomberg, founded in 2012 by two IIT Mumbai alumni, began as a technology consulting firm for scientific organizations (ISRO, BARC). In 2015, it pivoted to manufacturing Brushless Direct Current (BLDC) motor-based ceiling fans, which save up to 65% energy compared to traditional fans. This was a breakthrough in a stable, innovation-starved category dominated by incumbents like Usha and Crompton. The company later expanded into other home appliances.

Evolution and Pivots

Atomberg’s journey illustrates how a startup uses outbound digital marketing through multiple strategic pivots:

Phase 1: B2B Focus (2015–2016)

• Targeted the ceramics industry in Morbi, Gujarat, where heavy-duty fans run for drying, consuming significant power.
• BLDC fans’ energy savings (60–65%) offered clear value, given industrial electricity costs are higher than residential.
• Result: Limited market growth; the opportunity was far larger in the consumer segment.

Phase 2: B2C – D2C Digital First (2016–2019)

• Shifted to a business-to-consumer (B2C) model, leveraging digital marketing.
• Launched a website, sold via own site and third-party e-commerce platforms (Amazon, Flipkart).
• Set up a customer contact center for queries.
• Target customers: Affluent, tech-savvy, young urban households.
• Marketing message: Education-based content highlighting BLDC benefits and long-term energy savings.
• Brand positioning: Premium, innovative, sustainable. Priced at ~₹3,000–3,500 vs. standard fans at ₹1,500–2,000.
• Key insight: Over 95% of online sales came from third-party e-commerce sites; own website accounted for less than 5%.

Phase 3: Omnichannel Expansion (2019–onwards)

• Why pivot? 80% of fan purchases still occurred in physical retail stores. Online-only limited growth.
• Piloted retail distribution in Mumbai (FMCG-style structured network), then expanded to western India and beyond.
• Launched the “Why Not” campaign on YouTube and own channels, later moving to expensive TV campaigns (2022).
• Goal: Drive awareness and consideration online while enabling offline purchase.

Customer Journey Phenomena in Omnichannel

As Atomberg moved to physical stores, two complementary behaviors emerged:

Both phenomena underscore the need for consistent brand presence across channels and careful management of pricing and availability.

Atomberg in 2022 – Position, Challenges, and Opportunities

By 2022, BLDC technology was no longer proprietary; competitors (Crompton, Usha, Bajaj) had introduced similar energy-efficient, remote-controlled, stylish fans. Atomberg’s differentiation eroded.

Key Metrics (2022)

• Revenue: ~$80 million
• Market share: 20% of the premium fan market, but only 6% of the overall fan market
• Channel revenue split:
  • Own website: 5%
  • Third-party e-commerce: 25%
  • Offline retail: 75%
• Distribution reach: 15,000 outlets in 150 towns/cities (leaders had 70,000–75,000 outlets)

Core Challenges

1. Loss of differentiation – BLDC and features became industry standard; consumers could now buy similar products from trusted brands at lower prices.
2. Omnichannel price coordination – Price discrepancies between online and offline channels cause retailer rebellion or loss of shelf space. Solution: separate stock-keeping units (SKUs) for online vs. offline.
3. Logistics and inventory strain – Rapid growth required scaling production, warehousing, and ensuring stock availability across 15,000 outlets without excessive inventory.
4. Increased costs – Physical distribution and TV advertising raised operational expenses; company was not yet profitable (acceptable for growth-stage startup).
5. Seamless customer experience – Managing consistent pricing, product availability, and service across diverse channels.

Exam tip: Atomberg’s journey is a classic example of how digital outbound marketing evolves from pure D2C to omnichannel. The key lesson: “Meet customers where they buy.” Despite strong online brand awareness, the majority of sales (75%) came from offline because that’s where the market was. Know the metrics: own website 5%, e-commerce 25%, offline 75%.

Key takeaways

• Atomberg started as a tech consultancy, pivoted to BLDC fans, and made three major marketing pivots: B2B → D2C → omnichannel.
• The “Why Not” campaign illustrates outbound digital marketing (YouTube) scaling to TV.
• Webrooming and showrooming are crucial behaviors in omnichannel retail; they require integrated digital and physical presence.
• Price consistency across channels is a major challenge; SKU differentiation can help.
• By 2022, offline retail accounted for 75% of revenue, despite Atomberg’s digital-first origins.
• Loss of product differentiation forced the company to compete on brand, distribution, and customer experience rather than unique technology.

Atomberg Marketing Strategies

Atomberg's marketing strategy evolved across two distinct phases: a digital-led, e-commerce-only phase (2016–19) and an omnichannel phase (2019–22) adding physical retail. The Six M’s framework (Mission, Market, Message, Media, Money, Measurement) captures the shift.

Phase 1 (2016–19): Digital-Led, E-commerce Only

Phase 2 (2019–22): Omnichannel Growth

Consumer vs. Channel Partner Campaigns

Exam tip: The Six M’s framework is a standard case‑analysis tool. Be ready to apply it to any company’s campaign – the shift from pure digital to omnichannel is a classic growth‑stage pattern. The “80% offline” stat often appears in exams to justify why digital-only is insufficient in such markets.

Key takeaways

• Atomberg’s first phase (2016‑19) used Six M’s: awareness, urban/inverter‑user target, energy‑efficiency message, digital‑only media, low budget, conversion & review metrics.
• Second phase (2019‑22) added retail: mission = offline scale; market included intermediaries; message challenged incumbents; media added TV & BTL; money higher; measurement focused on dealer uptake.
• Pros: strong online conversions, tech differentiation, high digital ROI. Cons: missed 80% offline market, copycat competition, small dealer network, rising costs.
• Consumer campaigns are aspirational; channel partner campaigns are business‑focused with different content, channels, and metrics.
