In the Adstudio assistant
In the app, TikTok is read at campaign level, so a campaign's CTR trend can point at fatigue, and the per-ad check runs over MCP.
TikTok Ads · Creative fatigue
Are my TikTok Ads creatives fatigued?
A TikTok creative is fatigued when its frequency rises while CTR and completion fall and its cost per conversion climbs. Through Adstudio MCP, your AI reads those per ad, by day, and lists the videos to refresh.
The numbers that matter
What to read first.
- Frequency by ad
- How often the same people see the video.
- CTR by ad over time
- Falls first.
- Views at 100% over time
- Viewers stop finishing a video they have seen.
The method
How to break it down.
- 01Read each ad's frequency, CTR and completion by day.
- 02Flag the videos whose frequency climbs while their CTR slides.
- 03Check cost per conversion to see what the fatigue costs.

Prompts
Copy one and ask.
- “Which TikTok ads have rising frequency and falling CTR over the last 3 weeks?”
- “List TikTok ads whose completion rate fell by more than a third since launch.”
Limits
What Adstudio will not tell you.
- Rising frequency with falling CTR is a signal; a placement or audience change can look the same.
