Design Tips That Improve CTR
1. Use complementary colors — YouTube's UI is white and red. Blue, yellow, or green backgrounds stand out more.
2. The 5-second test — View at 100×56 px. If you can't tell what it's about, redesign.
3. Emotional faces beat text — Thumbnails with expressive faces get 38% more clicks.
4. Consistent branding — Same font, style, and positioning builds channel recognition.
5. Bold, thick fonts — Thin fonts become unreadable at thumbnail size.
