Five lines per test
- What was tested: the hypothesis and the one thing that changed.
- What happened: the metric for control and variants, over the agreed days, with the spend.
- Verdict: win, loss or not enough data, using the rule written in the brief.
- What we learned: one sentence that could apply to another client in the same category.
- What next: the next test, or a reason to stop testing this idea.
Made-up example
Hypothesis: a question in the first line keeps more people watching. Result: hook rate 31 percent against 24 percent for the control after 7 days and equal spend. Verdict: win. Next: test the same opening with a different offer.
Where it lives
- Next to the creative IDs, so anyone opening the ad can find its history.
- In the client report as one line, not one page.
