Why TikTok Ads's view of creative fatigue is misleading

  • TikTok is a discovery channel — it creates demand but conversions happen days later on other channels
  • Last-click attribution gives zero credit to TikTok when a customer discovers on TikTok then buys via Google
  • 21-day consideration cycles for beauty/fashion mean TikTok's impact is invisible in 7-day windows

How causal inference measures creative fatigue for TikTok Ads

  • Causal inference measures the downstream revenue created by TikTok — even when conversion happens on Google
  • 40-day analysis window captures the full consideration cycle for beauty, fashion, and supplements brands
