What Good Weekly Ad Reporting Actually Looks Like

Most weekly paid-media reports are a performance summary dressed up as analysis. Spend was X, CPA was Y, ROAS was Z, here's a chart. They describe what happened accurately and explain nothing. The person reading them learns whether the numbers went up or down; they don't learn why, or what to do about it. That's not a report — it's a dashboard with a subject line.

The difference between description and analysis

A descriptive report tells you CPA increased 18% week over week. An analytical report tells you CPA increased 18% week over week because broad match expansion pulled in a set of informational queries that have historically low intent, and the conversion rate on those queries is 0.4% versus 2.1% on exact match terms. One of those reports drives a decision. The other generates a follow-up question.

What a useful weekly report contains

The structure that consistently drives action has three parts: what changed in the account this week (decisions made, campaigns launched or paused, bids adjusted), what moved in performance and what likely caused it (tied to the changes), and what the recommended next action is. The first section is the record — what happened at the account level. The second is the diagnosis — what the record caused. The third is the prescription — what to do next. Without the first section, the second is speculation. Without the second, the third is guesswork.

The record is what makes the report credible

The reason most weekly reports can't explain why performance moved is that the person writing the report doesn't have a reliable record of what changed in the account. They have the metrics. They don't have the change log. When the account change history is complete and timestamped, the weekly report writes itself: here's what changed, here's what followed, here's what it means for next week. That's analysis. Everything else is description.
