The 500-character limit
YouTube allows 500 characters in the tag box in total. It counts the commas between tags, and a tag with a space in it counts two extra characters, because YouTube wraps it in quotes. So a list can hit the limit sooner than it looks.
With Fit to 500 characters on, the generator keeps tags in order, strongest first, until the next one wouldn't fit. The meter shows the count the way YouTube counts it.
Frequently asked questions
What is the character limit for YouTube tags?
500 characters for all tags together. Commas count, and a tag with a space counts two extra characters for the quotes YouTube adds around it.
How many tags should a YouTube video have?
There's no magic number. Five to fifteen tags that really describe the video is a good range, with your main keyword first.
Do tags help YouTube videos get views?
Only a little. YouTube says tags play a minimal role in discovery, mainly helping with misspellings. Titles, thumbnails and descriptions matter far more.
Where do I add tags on YouTube?
In YouTube Studio, open the video's details, click Show more and find the Tags box. Paste a comma-separated list and YouTube splits it into tags.
What's the difference between tags and hashtags?
Tags are hidden and only used by YouTube. Hashtags go in your title or description, are visible and clickable, and the first three can show above your title.
