Scenario

Pinecrest Grocers sells grocery in US. Last quarter it spent $195 M across three channels: brand (21%), paid search (44%) and paid social (35%).

The company recorded 22,297 conversions. Added together, the channel dashboards claim 31,216 — about 1.4x the real number.

Paid search reports the best return and the search team wants more budget. Brand reports the worst and is under pressure to justify itself. Attribution is last-click. Nobody has run a holdout test.

Your task

Advise the CMO. Your answer should provide:

  1. Analysis — what the reported numbers can and cannot tell you, quantified.
  2. Risks — what happens if you reallocate on last-click alone.
  3. Recommendation — a budget decision and the experiment that would prove it.

State any assumptions you make.

Hint
Reveal suggested structure

Separate correlation from incrementality. Last-click credits the final touch; demand generation appears worthless under it. Design a holdout before reallocating.
