Analyzing Attribution Data for Budget Allocation

A company uses a multi-channel attribution model and finds that social media contributes 20% of conversions, email marketing 50%, and paid search 30%. If the marketing budget is $100,000, how much should be allocated to email marketing to align with these results?

A $50,000

B $30,000

C $20,000

D $100,000

💡 Hint

Allocate budget proportional to each channel's contribution percentage.

Email marketing contributes 50% of conversions, so 50% of $100,000 is $50,000.

Comparing Attribution Models

Which statement correctly compares the first-click and linear attribution models?

A First-click distributes credit equally; linear gives all credit to the last channel.

B Linear gives all credit to the first channel; first-click distributes credit equally.

C First-click gives all credit to the first channel; linear distributes credit equally across all channels.

D Both models give all credit to the last channel.

B. Social Media

C. Paid Ads

D. All channels share credit equally

3. Final Answer:

   Channels appearing earlier in the customer journey get no credit -> Option D

4. Quick Check:

   Last-click ignores earlier channels [OK]

Hint: Last-click credits only the final channel [OK]

   Last-click and first-click give all credit to one channel; time decay gives more credit to recent channels, not equal.

4. Final Answer:

   Linear attribution -> Option A

5. Quick Check:

   Fair credit = Linear attribution [OK]

Hint: Linear model shares credit equally among channels [OK]

Common Mistakes:

• Choosing last-click or first-click for fairness
