Your thumbnail is doing the selling before the video even starts.
Most creators miss three things: clarity, promise, and contrast. Fix those and your CTR — and watch time — jump.
Quick starter (do this now):
• Use one bold headline (4 words max).
• Show a clear focal element (face or symbol).
• High contrast + readable text at small sizes.
Thumbnails don’t need to be pretty — they need to be decisive.
If you want me to review one of yours, comment THUMBNAIL and I’ll pick a few to critique.
