YouTube Description Generator

A YouTube description generator assembles a description with a clear opening summary, key points, chapters, links and up to three hashtags. The first two lines matter most because they appear in search results and above the fold.

It runs entirely in your browser. Nothing you paste or upload is sent to a server or stored.

How to read the result and act on it

Start with the opening two lines, because they appear in search results and above the fold. They should state what the video covers and include your main keyword naturally, in a sentence a person would write. Then review the key points, which should match what the video actually says, not extra marketing. Check the chapters: the first must be 0:00 and timestamps should be in order. Look at the links section and keep only the ones a viewer needs, with the most useful first. Keep the hashtags to the three you want shown above the title. Finally, paste the result into YouTube Studio, read it once on a phone preview, and trim anything that repeats the title without adding information.

Common mistakes to avoid

A frequent mistake is writing a long keyword paragraph at the top instead of a clear summary. Descriptions are for viewers first, and stuffing phrases makes the opening unreadable. Another is placing the important link below a block of text so nobody sees it. Do not add more than three hashtags thinking more is better; YouTube shows only the first few and ignores a video's hashtags entirely if it has more than 15. Also avoid inventing chapters that do not match the video, since viewers click them and leave when the content differs. Finally, copying one description template across every upload makes your videos look alike in search, so always change the summary and key points.

How long can a YouTube description be?

Up to 5,000 characters, but only the first lines are visible without clicking more.

Do links in descriptions help SEO?

They help viewers. YouTube links are nofollow for search ranking purposes, so use them for traffic, not rankings.

What makes a good description?

A clear summary of the video in the first two lines, chapters, and context for the topics covered.

What should the first line of a YouTube description say?

State what the video covers and who it helps, using your main phrase naturally. The first lines show in search results and before the Show more fold, so they act like a short summary. Put links and promotion after that opening.

Should I put timestamps in the description?

Yes if the video is long enough to benefit. Start with 0:00, list at least three chapters and use clear labels. Chapters help viewers jump to what they need and appear on the video's progress bar once YouTube accepts the list.
