Sample answer

Cortex - answering with 7 sources

How long should creative run before refreshing on a TikTok Smart+ ad group?

TikTok's documented guidance is to keep 5-7 creative variants per ad group and refresh at least once a week to maximize ROAS^[1]. Performance typically begins to decline after 7 days on the same creative set - the platform measures this as "creative fatigue" and downranks the ad group in the auction once 2-second view rate and CVR start drifting down^[2].

The Smart+ learning phase needs roughly 50 conversions in the trailing 7 days to stabilize^[3], so the cadence rule is: never refresh an ad group still in learning. Wait until the system has exited learning, then swap in 2-3 new variants alongside the existing winners rather than replacing the whole set^[4]. Replacing every creative at once resets the ad group's learning history and rebuilds CPA from scratch.

Diversify by creator, format, and hook, not just by visual edit. TikTok's own data shows ad groups with diversified creative sources see +10 to +12% higher conversions than groups refreshed only with visual variants of the same source asset^[5]. Add new Spark Ads from authorized creator accounts to the rotation - Spark Ads keep social proof on the original post and historically deliver higher 6-second view rate than non-Spark in-feed^[6].

The Cortex Creative Sentry watches 2s view rate, 6s view rate, and CVR per creative in 24-hour windows. When any variant breaches the historic mean by more than 1.5 standard deviations, it triggers a refresh recommendation linked to the ad group and the specific underperforming asset^[7].

Refresh creative weekly with 5-7 variants per ad group. Never replace the whole set at once - it resets learning and rebuilds CPA from zero.

Generate the event_id at the moment of the user action and pass it to both Pixel and Events API for the same event - that's the only way TikTok deduplicates the duplicate hit.

Never raise a Smart+ ad group budget by more than 30% in 24 hours during learning phase. Triggers a hard re-enter of learning and stalls spend for 3-5 days.
