FAQ
Does this violate YouTube's Terms of Service?
No. We use the official YouTube Data API with OAuth to update thumbnails — the same method YouTube Studio uses. Thumbnail changes are a supported API operation.
How often are thumbnails rotated?
You choose: every 24 h, 48 h, or 72 h. We pull fresh CTR data before each swap so decisions are based on real impressions, not guesses.
What happens after a winner is found?
The winning thumbnail is locked in automatically and you receive an email summary. The test stops and your video keeps the best-performing image.
