I A/B test headlines all the time now. Same thumbnail, different text, see which gets more clicks. Couldn't do this before without my designer.

Changed the text on 20 old thumbnails in one afternoon. My CTR went up on videos that were basically dead. Should've done this months ago.

The text on my old thumbnails was too small to read on mobile. Went through and made everything bigger. Simple fix but huge difference.

Best Practices
Tips for Making Great Thumbnails
Keep text under 5 words. Shorter is always more readable at thumbnail size.
Use high contrast colors. White on dark, dark on light. No subtle color differences.
Add outlines or shadows. Text without effects disappears on busy backgrounds.
Test at mobile size. If you cannot read it small, viewers cannot either.
All caps for impact. Lowercase works for some niches but caps read easier small.
Common Mistakes
What to Avoid
Changing text without checking readability. New text might be longer and need resizing.
Using thin fonts. Bold and thick fonts survive thumbnail compression.
Forgetting mobile preview. Desktop text often fails on phone screens.
Cramming too many words. Edit text to fewer words, not just different words.
Skipping the shadow or outline. Text needs definition against any background.
