Key Findings
3-5 words is the sweet spot
Thumbnails with 3-5 words of text outperform all other lengths by an average of 28%, balancing information with readability.
Zero text can work but is riskier
No-text thumbnails either perform 15% above or 25% below average - they succeed when the image is self-explanatory and fail when context is needed.
More than 7 words kills performance
Each word beyond 7 reduces CTR by approximately 8%, as text becomes unreadable at mobile thumbnail sizes.
ALL CAPS outperforms mixed case
Text in ALL CAPS gets 17% more clicks for entertainment content, though mixed case performs better for educational content.
