How to Write a YouTube Video Description That Gets Found?
YouTube allows 5,000 characters. Here is how to use the first few lines well, and what to skip.

Summary
A good YouTube video description opens with one or two plain sentences that say what the video answers, using the phrase people search for, then adds chapters, useful links and a short call to action. YouTube Help says descriptions have a limit of 5,000 characters, but viewers mostly see the opening lines before they tap "more", so put the important part first.
Start with the answer
Write the first lines for a person, not a keyword list. Say what the viewer will learn and who it is for. YouTube says it looks at how well the title, description and video content match a search, so the main phrase belongs here naturally.
Add chapters
Timestamps in the description turn into chapters that help viewers jump to the part they need. See our chapters guide for the format YouTube expects.
Link with purpose
- One or two related videos or a playlist
- Resources you mention in the video
- Affiliate or sponsor links, clearly disclosed
Keep hashtags light
A few relevant hashtags are fine. Stuffing the description with tags or repeated keywords can break YouTube's spam policies.
A simple template
- Two-sentence summary with the main phrase
- Chapters
- Links and resources
- Disclosure and channel info
