Stop leaving the space under your video empty.

Two opening lines that state what the video is, in the words a viewer would use — that is all most people see before the fold. Then a short paragraph on what the video covers, a chapter list with timestamps, and your links. Anything you want understood should read as a sentence; a pile of keywords at the bottom does nothing for viewers and very little for search.

The field holds 5,000 characters, and most videos are well served by 150 to 300 words. Only about the first 150 characters show before the More button, so length is mostly about the people who choose to expand it. Longer is not better on its own — a padded description does not rank higher, it just gets read less.

YouTube reads the description for context alongside the title, the transcript, and how people actually behave on the video. It is one signal among several, and nobody outside YouTube can put a number on its weight. In practice, describing the video clearly helps more than repeating the keyword, because the surrounding signals — watch time, click-through, session length — are the ones doing most of the work.

Give them their own block, usually right after the opening paragraph. For YouTube to turn them into chapters, the first timestamp has to be 00:00, you need at least three of them, and each chapter must run at least ten seconds. Write one per line in the format 00:00 Chapter name, with nothing else on the line.

The top section, yes — it should describe that specific video. Boilerplate like links, gear lists, and socials can safely repeat at the bottom. Pasting the same opening across a whole channel gives viewers nothing to read and gives YouTube nothing to tell your videos apart with.

From a description, up to three hashtags that YouTube considers most engaging may appear by the video title; they are not necessarily the first three entered. Keep them directly related to the video. If the content has more than 60 hashtags, YouTube ignores every hashtag on that content.

One or two lines is plenty. Shorts viewers rarely open the description, so its real audience is search and the hashtag system: state the topic plainly, add up to three relevant hashtags, and stop. Timestamps and chapter lists do nothing on a sixty-second vertical video — save the full template for long-form uploads.

Read them off what you have already published instead of retyping them. Paste your public channel handle under the generated description and this tool reads your last 50 public descriptions, keeps the lines that appear in at least half of them, and attaches those to the new description so one copy gives you both. If a destination recurs but its address changes every time, you get the destination named and the count, and you paste the current link yourself — we will not guess a URL, because a guessed URL is a broken one.

Yes, it's free with no account needed, and each run returns one complete description.
