Creative testing often shrinks when ad spend cools because teams reduce exploration and keep fewer proven assets in rotation. Verified AppGrowing data shows Puzzle ads fell 15.4 percent and creatives fell 13.3 percent, while Shopping app ads fell 11.9 percent and creatives fell 34.1 percent from 2026-06-02 to 2026-07-02.
Why does creative testing shrink
When ad volume declines, teams often cut the riskiest part of the workflow first. That is usually new creative exploration. The remaining work focuses on retained creatives, small variants, and lower risk messages.
TikTok shows a large contraction signal. Ads fell 63.7 percent and creatives fell 44.8 percent. This does not prove why TikTok changed spend, but it does show that both delivery and creative activity declined in the same period.
How should teams diagnose the decline
If ads and creatives fall together, treat it as broad contraction. If creatives fall faster than ads, check whether testing has been compressed. If ads fall faster than creatives, check whether the team is still exploring even while delivery cools.
Adventure ads fell 42.1 percent while creatives fell 8.8 percent. Shopping ads fell 11.9 percent while creatives fell 34.1 percent. These are different contraction shapes, so they should not produce the same creative response.
What should UA teams do next
Use ad decline as a trigger for retained creative analysis. Do not copy fewer new creatives just because the competitor is producing fewer. Identify which creatives remain visible after the decline, then decide whether to write variants.
