How long should a video description be?

The length matters less than the first three lines, which should stay under about 150 characters and make sense alone. Beyond that, as long as it is useful — chapters, links and further explanation all have a place.

Do lots of keywords help rankings?

No — repeating a keyword stopped helping long ago and can make a description look like spam. One natural mention in the first sentence is far more useful than ten forced ones.

Does this work without AI?

Yes — the descriptions are assembled in your browser from a written skeleton, so a result always appears. A language model, where available, only replaces that with a more tailored version.

What this is

A video description is the text beneath a video that explains it to viewers and to search engines at once. The part that decides most is its first few lines, because that is all anyone sees before tapping 'more' — and it is also the part most often used as the snippet in search results. The descriptions here put a self-contained summary at the front, then give you a chapter and links skeleton to fill in.

How it works

Timestamps are written as [00:00] placeholders for you to fill in once the edit is final. Wrong numbers are worse than none, because a timestamp that misses drops a viewer somewhere they did not want and they leave.

Your main keyword belongs in the first sentence, naturally, rather than repeated throughout. Forced repetition no longer helps rankings and makes the description read like a machine wrote it — which reduces the chance anyone reads as far as your links.
