Why Attribution models (last-click, multi-touch) in Digital Marketing? - Purpose & Use Cases

The Big Idea

What if you could know exactly which ad made your customer buy, without guessing?

The Scenario

Imagine you run an online store and want to know which ads or emails helped customers buy your products.

You try to track every step manually, writing down every click and message a customer saw before buying.

The Problem

This manual tracking is slow and confusing because customers often see many ads and messages before buying.

It's easy to miss important steps or blame the wrong ad, leading to bad decisions and wasted money.

The Solution

Attribution models automatically assign credit to different ads or messages based on how they influenced the customer's journey.

Last-click gives credit to the final step, while multi-touch shares credit across all important steps.

Before vs After

✗ Before

Track each customer click and message manually in a spreadsheet.

✓ After

Use an attribution model to automatically assign credit to each marketing touchpoint.

What It Enables

It helps marketers understand which ads truly drive sales and spend money smarter.

Real Life Example

A company uses multi-touch attribution to see that both a Facebook ad and an email helped a customer buy, so they keep investing in both channels.

Key Takeaways

Manual tracking of customer journeys is slow and error-prone.

Attribution models assign credit fairly to marketing efforts.

This leads to better decisions and more effective advertising.

Practice

1. What does the last-click attribution model do in digital marketing?

easy

A. Distributes credit based on ad cost

B. Gives all credit to the final ad clicked before purchase

C. Ignores the last ad clicked and credits the first one

D. Shares credit equally among all ads seen

Solution

1. Step 1: Understand last-click attribution

   Last-click attribution assigns 100% credit to the last ad clicked before a purchase.

2. Step 2: Compare with other models

   Unlike multi-touch models, it does not share credit among multiple ads.

3. Final Answer:

   Gives all credit to the final ad clicked before purchase -> Option B

4. Quick Check:

   Last-click = final ad credit [OK]

Hint: Last-click means credit goes to the last ad clicked [OK]

Common Mistakes:

• Thinking credit is shared among all ads
• Confusing last-click with first-click attribution
• Assuming cost affects credit distribution

2. Which of the following correctly describes a multi-touch attribution model?

easy

A. It ignores all ads except the most expensive one

B. It gives all credit to the first ad clicked

C. It shares credit among multiple ads that influenced the customer

D. It credits only the ad with the highest click rate

Solution

1. Step 1: Define multi-touch attribution

   Multi-touch attribution divides credit among several ads that helped influence the customer.

2. Step 2: Eliminate incorrect options

   It does not give all credit to just one ad or ignore ads based on cost or click rate.

3. Final Answer:

   It shares credit among multiple ads that influenced the customer -> Option C

4. Quick Check:

   Multi-touch = shared credit [OK]

Hint: Multi-touch means credit is shared among ads [OK]

Common Mistakes:

• Confusing multi-touch with last-click
• Thinking only one ad gets credit
• Assuming credit depends on ad cost

3. Consider a customer who saw three ads: Ad A, Ad B, and Ad C. They clicked Ad A first, then Ad B, and finally Ad C before purchasing. In a last-click attribution model, which ad gets full credit?

medium

A. Ad A

B. All ads share credit equally

C. Ad B

D. Ad C

Solution

1. Step 1: Identify the last ad clicked

   The customer clicked Ad A, then Ad B, and lastly Ad C before purchase.

2. Step 2: Apply last-click attribution rule

   Last-click attribution gives 100% credit to the final ad clicked, which is Ad C.

3. Final Answer:

   Ad C -> Option D

4. Quick Check:

   Last-click credit = last ad clicked [OK]

Hint: Last-click means credit goes to the last clicked ad [OK]

Common Mistakes:

• Giving credit to the first or middle ad
• Sharing credit equally in last-click model
• Confusing last-click with multi-touch

4. A marketer uses a multi-touch attribution model but notices all credit is going to only one ad. What is the most likely error?

medium

A. They are actually using a last-click model by mistake

B. They shared credit equally among all ads

C. They ignored the last ad clicked

D. They gave credit based on ad cost

Solution

1. Step 1: Understand expected multi-touch behavior

   Multi-touch should share credit among multiple ads, not just one.

2. Step 2: Identify why all credit goes to one ad

   If all credit goes to one ad, likely the last-click model is used instead of multi-touch.

3. Final Answer:

   They are actually using a last-click model by mistake -> Option A

4. Quick Check:

   Single ad credit = last-click, not multi-touch [OK]

Hint: All credit to one ad? Check if last-click model is used [OK]

Common Mistakes:

• Assuming multi-touch always shares credit equally
• Ignoring model settings
• Confusing ad cost with credit assignment

5. A customer interacted with three ads: Ad X (first click), Ad Y (viewed but not clicked), and Ad Z (last click). Using a multi-touch attribution model that gives 40% credit to first click, 20% to views, and 40% to last click, how is the credit distributed?

hard

A. Ad X: 40%, Ad Y: 20%, Ad Z: 40%

B. Ad X: 33%, Ad Y: 33%, Ad Z: 33%

C. Ad X: 0%, Ad Y: 50%, Ad Z: 50%

D. Ad X: 100%, Ad Y: 0%, Ad Z: 0%

Solution

1. Step 1: Identify credit percentages per interaction type

   First click gets 40%, views get 20%, last click gets 40% credit.

2. Step 2: Assign credit to each ad

   Ad X is first click -> 40%, Ad Y is viewed -> 20%, Ad Z is last click -> 40%.

3. Final Answer:

   Ad X: 40%, Ad Y: 20%, Ad Z: 40% -> Option A

4. Quick Check:

   Credit split matches model percentages [OK]

Hint: Match credit percentages to ad interaction types [OK]

Common Mistakes:

• Ignoring view credit
• Splitting credit equally instead of weighted
• Confusing first and last click percentages
