Review cost per result, relevance, engagement rate, and conversions per ad set against written targets – the Metrics and Analysis of MAA that turn $7 tests into decisions.
Category: Dollar a Day Campaigns
Use this when a 7-day test window closes – every ad set now owes you a verdict, and the verdict comes from numbers, not impressions of impressions.
Inputs
- Per-ad-set results for the full window: spend, results, cost per result, engagement, relevance/quality diagnostics, conversions
- The target CPA/ROAS and engagement baseline from Goals (GCT)
- The test log with each cell's hypothesis
Steps
- Export results per ad set after the full 7-day window – never judge a partial week.
- Put every number next to its target. Cost per result without a written target is trivia; Goals defined what winning means before launch.
- Read engagement quality, not just quantity: shares and substantive comments outrank reactions; on video, watch time and completion rate are the truth serum.
- Check relevance/quality diagnostics per ad set – content-audience mismatch shows up there before it shows up in cost.
- Decompose differences: when two ad sets share a creative, the audience explains the gap; when they share an audience, the creative does. (Same logic as apply-metrics-decomposition in Stage 6.)
- Bucket every ad set: winners (beat target), watch list (near target with improving trend), losers (everything else).
- Write the Action line for each bucket – scale, hold, or kill. Analysis is not finished until every row carries a verb.
- Archive results and lessons to the running test log so next week's matrix starts from knowledge, not memory.
Definition of done (QA checklist)
- Every ad set scored against a written target for cost per result and engagement
- Winners / watch list / losers buckets assigned, with decomposition notes explaining why winners won
- An action verb (scale / hold / kill) recorded per ad set
- Test log updated with results and one-line lessons
- Linked back to the definitive article and relevant siblings
- Complies with Blog Posting Guidelines (if it publishes content)
Example(s)
- Example needed – run the Meta-Article Prompt after first real run (best first candidate: the day-7 readout of a live $1/day matrix showing one audience beating another on the same creative).
