Quick setup · Short test

Make two thumbnails for the same video: one showing the problem and one showing the outcome. Use a main subject and brief readable text. Review at phone-tile size. If the message disappears, improve contrast and composition. The title should support the image without inventing a promise.

A falling CTR with increasing impressions is not automatically a failure: the audience may have broadened. Separate search, home and subscription traffic. Do not change topic, title and thumbnail together and then attribute every result to one color.

1. Select or set: Thumbnail → 16:9 / 1280 × 720.
2. Write down: Thumbnail text → 2–4.
3. Select or set: A/B/C → Permissions ✓.
4. Save: Results → Results → One change at a time.

Before you go live

Keep your existing configuration and original source file first. Change one parameter at a time. Check a short recording or the actual viewer output, rather than relying only on the editor. Restore the recorded baseline if the result gets worse.

1. One change at a time → Baseline.
2. Viewer output → Short test.
3. Results → Backup.
