Frequently Asked Questions

How does the thumbnail rotation work?
We connect to your YouTube account via OAuth, then automatically swap thumbnails on your videos at scheduled intervals using the YouTube Data API. You upload multiple thumbnail variants and we handle the rest.
How is CTR tracked and measured?
We pull click-through rate data directly from the YouTube Analytics API for each thumbnail variant during its active window, then compare performance across all variants to identify the winner.
Is my YouTube account safe?
Yes. We use official OAuth 2.0 with read/write scopes limited to thumbnail management only. We never store your password and you can revoke access at any time from your Google account settings.
