Is there a limit on keywords on each video and will repetitive words be tagged as spam?

The keyword limit is set at 25 keywords, 1000 characters, and can only contain alphanumeric characters (0-9, a-z, A-Z, -, space)

Your keywords determine which category will be chosen for your video. Use keywords like health, technology, science, politics, food, etc., to make sure your video goes into the category you wish.

We recommend content creators to only use appropriate and related keywords on their videos.
