7 Design Rules
- One focal point: cluttered thumbnails get ignored.
- Faces with emotion: expressive faces boost CTR (when relevant).
- High contrast: must pop on both light and dark mode.
- Curiosity gap: raise a question the video answers.
- Don't repeat the title: thumbnail + title = one message.
- Consistent style: recognizable branding across videos.
- Test on mobile: 70% of views are mobile — zoom out and check.
