Troubleshooting
- No results — Verify the video ID (11 characters, exact copy). Very new videos (<24 hrs) may not be indexed yet. Try a more popular reference video.
- Low similarity scores — A unique thumbnail design can actually be a competitive advantage. Low scores suggest original positioning.
- Results don't match expectations — The algorithm matches visual composition, not topic. Add a category filter in your prompt to narrow results.
- Quota limit reached — If you've hit your daily limit, Upgrade to Pro for higher quota limits.
Thumbnails are public YouTube assets. Use results for research and inspiration only — never copy thumbnails exactly.
