      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%

      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
