Why the right number of hashtags matters

Using too many hashtags can look like spam. It can push your video down in search.

It can also confuse viewers. They might not click if they see a long list.

Finding the right number helps YouTube show your video to the right people.

Best practice for number of hashtags

YouTube lets you add up to 15 hashtags. After 15, it ignores the rest.

Aim for three to five hashtags. It is enough to cover your topic.

Focus on quality. Pick tags that match your video content.

Tips for choosing hashtags

Think about what viewers search for.

Use a mix of broad and specific tags.

Check your top videos for ideas.

Keep tags simple and easy to read.

    "tags": ["fitness", "workout", "health"]
