|---|---|---|
| Hook (first 100-150 chars) | Top | Always visible without expansion |
| Primary URL | First 2-3 lines | Always visible |
| Chapters / timestamps | Middle | Visible after expansion |
| Long-form context | Middle | Visible after expansion |
| Channel links / socials | Bottom | Visible after expansion |
| Hashtags | Anywhere (3 max for SEO) | Auto-link to tag pages |
Above-the-Fold Strategy
Mobile YouTube shows ~150 chars before "...more". Desktop shows ~200 chars. Use this real estate wisely:
- Hook (1 sentence) ??” what value the viewer gets.
- Primary URL ??” your main conversion goal.
- "Subscribe" CTA (optional).
