How to use it

  2. 02

    Get 25 tags

    Specific phrases first, broader words after, all inside the 500 character limit.

  3. 03

    Paste them into YouTube

    Copy all, then paste into the Tags box under Show more in the upload screen.

How to choose tags that help

Put your most specific phrase first. If the video is about fixing a flat bike tyre, lead with that exact phrase, not with the word cycling.

Use phrases people would type, two to four words long. Add a few common misspellings if your topic has them. That is the one job YouTube says tags do well.

Do not add tags that have nothing to do with the video. YouTube treats misleading tags as a policy problem, and they bring the wrong viewers anyway.

Tags are a small signal. The title and thumbnail decide whether anyone clicks, so spend your time there.

Questions

How many tags should a YouTube video have?

There is no required number. YouTube allows 500 characters in total. Ten to twenty-five specific tags is plenty.

Do tags help a video rank?

A little. YouTube says the title, thumbnail and description matter more, and that tags help most when a topic is often misspelled.

Where do I put tags on YouTube?

In YouTube Studio, open the video's details, click Show more and paste them into the Tags box, separated by commas.

Are tags the same as hashtags?

No. Tags are hidden and go in the Tags box. Hashtags are visible, start with # and go in the title or description.

Is the tag generator free?

Yes, with no sign-up. There is a daily limit so everyone gets a turn.
