How to Write a YouTube Description That Ranks (Template + Examples 2026)
Free tool: Description Generator
Your description is the only place on YouTube where you can explain your video in full sentences — and both YouTube and Google read it to decide which searches your video should appear in. Yet most creators paste a few links and move on.
This guide gives you a proven description structure, copy-paste templates for different video types, and the mistakes that quietly hold videos back. Short on time? Our free AI description generator writes the first draft for you.
Why YouTube Descriptions Still Matter
YouTube cannot watch your video the way a person does. It relies on your title, description, captions, and viewer behavior to understand the topic. A clear description gives it more context, which helps your video show up for the right searches and in suggested videos next to related content.
Descriptions also show in Google results. Chapters from your description can appear as "key moments" in Google, giving your video more space on the results page.
The 6-Part YouTube Description Structure
- 1Hook with your keyword (first 1–2 sentences). Only about 150 characters show before "...more" and in search results. Say what the viewer gets and include your main keyword naturally.
- 2Summary (2–3 sentences). Expand on what the video covers using one or two related keywords.
- 3Chapters. Start at 0:00, list at least three sections, each 10 seconds or longer. Chapters improve navigation and can appear in Google.
- 4Call to action. Ask a specific question to drive comments, and invite viewers to subscribe.
- 5Links. Related videos, playlists, resources mentioned in the video, and your socials.
- 6Hashtags. Add 3 relevant hashtags — the first three appear above your title.

YouTube Description Mistakes to Avoid
- •Starting with links or "In this video..." — you waste the 150 characters that show in search.
- •Keyword stuffing or pasting a list of tags into the description. YouTube treats it as spam and can remove the video.
- •Piling on hashtags. More than 15 looks spammy, and past 60 YouTube ignores every hashtag on the video.
- •Copy-pasting the same description on every video. Keep a shared footer, but make the top unique.
- •Forgetting to update old descriptions with links to your newer, related videos.
Description Length: How Long Should It Be?
YouTube allows up to 5,000 characters. For most videos, 150–300 words is the sweet spot: enough context to rank, short enough that your links are easy to find. Long tutorials and podcasts can go longer with detailed chapters and show notes.
