How TACoS works
TACoS is ad spend divided by total revenue, including sales that came without ads. It shows how much your whole business leans on advertising. A TACoS under 10% is healthy for an established product. New launches often run 15% to 25% while ads build rank and reviews.
A falling TACoS while revenue grows means advertising is driving organic sales. Compare it to ACoS, which looks only at ad-attributed revenue, and to ROAS for campaign-level efficiency.
