How To Test A Thumbnail Before Publishing
You cannot know CTR before publishing, but you can catch obvious thumbnail problems before the video goes live.
View It Small
Check the thumbnail at mobile size. The subject and text should still be clear.
Use The Three-Second Test
Look away, then glance at the thumbnail for three seconds. If the idea is not clear, simplify it.
Compare It With Competitors
Put your thumbnail beside videos from the same niche. It should stand out without looking misleading.
Check The Title Match
The title and thumbnail should support the same promise without saying the exact same thing.
Ask A Cold Viewer
Show it to someone who does not know the video. Ask what they think the video is about.
