The guide

What the youtube description generator does, how to use it, and what to do with the result.

A YouTube description generator writes the text under your video for you: a strong opening, your keywords, chapter timestamps, links and hashtags. Describe the video and its main keyword, and you get a description structured the way YouTube and viewers expect, ready to edit and paste.

What a Good YouTube Description Includes

The opening lines matter most, because YouTube shows them before the "more" link and in search results. Lead with what the viewer will get and your main keyword, then add a fuller summary, chapters, links to related videos or products, and a call to action such as subscribing.

Using Keywords Naturally

Use your main keyword in the first sentence and a few related phrases through the description, the way you would say them out loud. YouTube reads descriptions to understand what a video is about, but stuffing keywords looks spammy and is against YouTube's policies.

Adding Chapters

Chapters split a video into sections viewers can jump to, and they can appear in search. To create them, list timestamps in the description starting with 0:00, with at least three timestamps, each chapter at least 10 seconds long.

Links, Calls to Action and Hashtags

Link to related videos, playlists and your site, and say plainly what you want viewers to do next. YouTube shows the first hashtags from your description above the video title, so use two or three relevant ones rather than a long list.

Edit Before You Publish

Treat the generated description as a strong first draft: check that every claim, link and timestamp is accurate for your video, and adjust the tone to sound like you.
