| description | Structure and read creative A/B tests across platforms — set up variants, decide when a result is real, and pick winners without fooling yourself on noise. Use when a user wants to test ads, compare creative variants, run an A/B test, or choose a winning ad. |
Creative Testing
Test to learn, then scale the winner. Most "winners" called early are noise. Reads are free; launching variants spends money, so confirm before shipping.

1. Test one thing at a time
Change one variable per test (hook, image, headline, offer, format) so the result is attributable. Testing five things at once tells you nothing about which one moved the number.
2. Set it up cleanly
Build variants with the creative skill or generate_image_ad / generate_video_ad / generate_text_ad, ship them in the same ad group / ad set so they compete on equal footing, and give each enough budget and audience to gather signal. Run campaign-preflight before launch.
3. Wait for enough data
- Judge on conversions and CPA where volume allows, on CTR only as an early proxy.
- Do not call a winner off a few conversions or one day; small samples swing wildly. State the volume behind the call.
- On Meta, respect the Learning Phase before comparing (see platform-meta).
4. Read and act
Pull results per variant: pull_<platform>_ads_performance(level="ad"). Pick the winner on the metric that matters (usually CPA or ROAS, not CTR). Scale it with the optimize skill, retire the losers, and feed what you learned into the next test.
Rules
- One variable per test; enough data before a verdict.
- Winner is decided on the conversion metric, not clicks, unless volume forces a proxy.
- Report the variants, the volume, the winner, and the next test to run. Watch winners for fatigue with the creative-fatigue-detector skill.
