In the Adstudio assistant
The assistant reads TikTok at account and campaign level, compares periods and attributes the change to campaigns, and runs the TikTok account analysis under each campaign's goal.
TikTok Ads · ROAS dropped
Why did my TikTok Ads ROAS drop?
TikTok Ads ROAS drops when payment value per conversion falls, fewer clicks convert, or clicks cost more — but first check that Complete Payment value is still being tracked, because without it TikTok reports a ROAS of zero. Adstudio reads ROAS only where value is tracked, compares the period with the one before, and finds which campaigns carried the drop.
The numbers that matter
What to read first.
- Complete Payment ROAS
- TikTok's ROAS; zero means 'not tracked', not 'no return'.
- Cost per conversion
- The other half of ROAS.
- CPM and CTR
- Together they set your cost per click on TikTok.
The method
How to break it down.
- 01Confirm Complete Payment value is tracked for the campaigns in question.
- 02Compare with the previous equal period and find the campaigns that moved.
- 03Split the change into conversion rate, value per payment and cost per click.
- 04Check CPM and CTR for the campaigns where cost per click rose.

FAQ

Usually because Complete Payment value is not tracked. Adstudio reports that as 'not tracked', never as a real zero return.
It compares trends and cost efficiency, and states that each platform counts purchases with its own attribution.
Creating an account costs nothing, but connecting an ad account needs a paid plan: Hobby at $19 a month, or Business at $39 per workspace a month. There is no trial, and the price does not depend on your ad spend.
