## Tips

- Write your description for humans first, algorithms second. A readable, helpful description naturally includes keywords.
- Use lists or bullet points in your description to improve scannability and keep viewer engagement high.
- Add timestamps for every major section; they improve both SEO and user experience (viewers can jump to relevant parts).
- Link to relevant videos and playlists in your description; this increases watch time and keeps viewers on your channel.
- Update descriptions for old videos with fresh keywords and links. An optimized description can revive old video views.

## Frequently asked questions

### How many keywords should I include in my description?

Include 1-2 instances of your primary keyword in the first 50 words, then 3-5 related keywords throughout. Avoid exact repetition; use variations instead.

### Do links in the description hurt my ranking?

No. YouTube allows internal and external links in descriptions. Link to your playlist and website freely. Links to external sites don't pass 'link juice' to other domains, but they improve user experience.

### Should I include a transcript in my description?

No, but you can add a summary. Full transcripts make descriptions too long and reduce scannability. Use captions on your video instead. Add a brief summary (2-3 sentences) and link to your full transcript if needed.

### How does YouTube truncate descriptions?

Desktop shows 157 characters before 'Show More'. Mobile shows 280 characters. Put your keyword and hook in the first 157 characters to ensure visibility without clicking 'Show More'.

### Can I use the same description for similar videos?

No. Each video should have a unique description with its own primary keyword. Duplicate descriptions can hurt your SEO and confuse YouTube's algorithm. Copy the structure but write fresh content for each video.
