Ad Creative Testing

Most creative "winners" are noise. Someone launches four ads in one ad set, looks after three days, sees one with a better click-through rate, and scales it. Three things went wrong at once: the ads were not shown to comparable people, the test stopped before it could tell a real difference from a lucky week, and the metric was clicks rather than the result the money is spent on.

This skill fixes all three. It sizes the test before it runs, so you know whether your traffic can answer the question at all. Then it reads the result on the metric that pays and says "no winner" when that is the answer.

When to use

The user is about to test ads, is looking at a test and wants to know what won, or is about to scale an ad on the strength of a short run.

Do not use it to rank ads that were never set up as a test. A report of five ads that ran at different times to different people is a performance history, not an experiment. Read it for ideas and then test the best idea properly.
