YouTube Description Generator FAQ
How long can a YouTube description be?
Up to 5,000 characters. Only the first two or three lines, about 150 characters, are visible before a viewer selects “…more”, and those lines also appear in search results. The character counter above the text shows the total.
Why are my chapters not showing?
YouTube creates chapters only when the list starts with 0:00, contains at least three timestamps in ascending order, and every chapter is at least ten seconds long. The generator checks these rules and tells you which one is broken.
Does the description help a video rank?
It helps YouTube understand what a video is about, and the opening lines influence whether people click from search. It is one signal among many; how viewers respond to the video matters more. Nothing you write in a description can guarantee a position.
How many hashtags should I use?
A few. YouTube displays the first three hashtags of the description above the title, and it ignores all hashtags on a video that has more than 60. Hashtags must be related to the video.
Should I repeat keywords in the description?
Use the main phrase once near the start and related terms where they fit naturally. Lists of repeated keywords are against YouTube’s policies on misleading metadata and can lead to a video being removed.
Can I put links in the description?
Yes. Addresses that start with https:// become clickable. Mention the most important link early, and label each one so that viewers know where it leads. Affiliate links should be disclosed.
What belongs in a video description
The description is the one place on a video page where you can speak to viewers and to YouTube at the same time, in plain text. Viewers use it to decide whether to keep watching and to find what you mentioned. YouTube uses it, together with the title and the video itself, to understand the subject. A description that serves both is short at the top and complete below.
The top matters most. On the watch page, and in search results, only the first lines are shown. They should say what the video is about, in the words a viewer would search for, and promise something specific. A greeting or a channel slogan in that position wastes the only text most people will read.
Below the fold, structure wins. Chapters let viewers jump to the part they need, and they appear as key moments in Google results. Links to products, sources and related videos save viewers from asking in the comments. A single call to action, to subscribe or to watch the next video, gives interested viewers somewhere to go. A few relevant hashtags connect the video to a topic page.
It is worth keeping a consistent layout across a channel. Regular viewers learn where to look, and you can reuse the lower part as a template: links to social accounts, equipment, and a standard closing line. What must be written fresh each time is the opening and the chapters, since those describe this video and no other.
