How to Write a YouTube Video Description (2026 Guide with Template)
A practical guide to writing YouTube video descriptions for businesses, with the rules that matter, a template you can copy and common mistakes to avoid.
Most business channels treat the YouTube video description as an afterthought: a line of text, a website link and a wall of hashtags. That wastes one of the few places where you can tell YouTube, and the viewer, exactly what the video is about and what to do next.
This guide covers what a YouTube video description does, what to put in the first lines, how to add chapters, links and hashtags, and a simple template you can copy for every upload.
What a YouTube description actually does
- Helps YouTube understand the video. Along with the title, captions and the video itself, the description gives YouTube context about the topic, which helps it decide when to show the video in search and suggestions.
- Helps viewers decide to watch. Part of the description appears in search results and under the video, so the opening lines work like a second headline.
- Moves viewers to the next step. Links to your website, product, booking page or a related video turn views into enquiries.
Write the first two lines for people, not for keywords
Only the first line or two show before a viewer taps “more”, so those lines carry most of the weight. Say plainly what the viewer will get from the video and include the main phrase people would search for, once, in a natural sentence. For example: “A 10 minute walkthrough of a 3 BHK at Sarjapur Road, with real room sizes and the view from every balcony.”
Avoid opening with “Welcome back to the channel” or a list of links. Those lines push the useful part out of sight.
Add chapters with timestamps
Chapters split a longer video into sections that viewers can jump between, and they can appear in search. To create them, list timestamps in the description. YouTube needs the first timestamp to start at 0:00, at least three timestamps in total, and each chapter to be at least 10 seconds long. Give each chapter a short, descriptive name rather than “Part 1”.
Links, hashtags and the rest of the description
- One main call to action. Put your most important link near the top, with a short line saying why to click it.
- Supporting links lower down. Related videos, playlists, social profiles and contact details.
- A short summary. Two or three sentences that expand on the topic in your own words. You have up to 5,000 characters, but most business videos need far fewer.
- Hashtags, used sparingly. Two or three relevant hashtags are enough. YouTube ignores every hashtag on a video if you add more than 60, and long lists look like spam to viewers.
- Credits and disclosures. Music credits, partners and a clear note if the video includes a paid promotion.
A YouTube description template you can copy
Use this structure for every business upload, and change the details each time:
- One or two sentences on what the viewer will learn or see, with the main search phrase used naturally.
- One line with your main call to action and link.
- Chapters, starting at 0:00.
- A short paragraph that adds context: who the video is for and what problem it solves.
- Links to related videos or a playlist.
- Your website, contact details and social profiles.
- Two or three relevant hashtags.
Mistakes to avoid
- Copying the same description onto every video. Each video deserves its own summary.
- Stuffing the same keyword again and again. It reads badly and does not help.
- Adding misleading tags or topics that have nothing to do with the video.
- Leaving out the one link that matters, or burying it under ten others.
- Forgetting to update links when a page or offer changes.
How this fits into a wider YouTube plan
A good description helps, but it will not rescue a weak video. Titles, thumbnails, the first 30 seconds and watch time matter more. If you need help with the videos themselves, our video production team in Bangalore plans and shoots them, and our video editing services cover YouTube edits, chapters and thumbnails.
Frequently asked questions
How long should a YouTube video description be?
Long enough to explain the video and point viewers to the next step. For most business videos that is 100 to 300 words. The limit is 5,000 characters, but there is no reward for filling it.
Do keywords in the description help a video rank?
They help YouTube understand the topic, especially in the first lines. They will not make up for a video people do not watch, and repeating keywords can hurt how the description reads.
How many hashtags should I use?
Two or three relevant hashtags are plenty. Using more than 60 makes YouTube ignore all of them.
Can I edit a description after publishing?
Yes. You can update the description at any time, for example to add chapters, fix links or reflect new offers.
