YouTube Hashtag Generator FAQ
How many hashtags should I use on YouTube?
YouTube's help page says that if a video has more than 60 hashtags, YouTube ignores all of them, and that up to 3 hashtags from your description can appear by the title. A short, relevant set works better than a long list, so this tool suggests up to 15. Our AI hashtag generator creates relevant tags to help your video show up in search results and suggested videos.
Where do YouTube hashtags appear?
Up to 3 of the hashtags in your description appear as links by your video title. Every hashtag in the description is also a link to a page of other videos with the same tag. If a video has more than 60 hashtags, YouTube ignores all of them.
Do hashtags help YouTube SEO?
A little. Hashtags tell YouTube and viewers what the video is about and link it to other videos with the same tag. The title, description and how long people watch matter far more, and YouTube may remove a video whose hashtags are unrelated or excessive.
Should I use trending hashtags?
Only if they are genuinely relevant to your video. Irrelevant trending hashtags can bring a few clicks but hurt watch time. The AI has no live trend data, so check a trending tag on YouTube before you add it.
What's the difference between popular and niche hashtags?
Popular hashtags have many videos competing for them, so a new video is hard to find there. Niche hashtags reach fewer viewers who care more about the topic. The generator suggests a mix of both, and you choose which to keep.
Can hashtags go in my video title?
While you can include hashtags in your video title, it's generally better to place them in the description. Hashtags in titles take up valuable character space that could be used for keywords and compelling text. YouTube can show up to 3 hashtags from your description by the title anyway, giving you the visibility benefit without sacrificing title optimization.
Should I use the same hashtags for every video?
No. Tag each video for its own topic: identical hashtags on every video tell viewers and YouTube nothing about the one in front of them. Describe each video separately and the generator suggests tags for that subject.
Is there a limit to hashtag generation?
Generating needs a PostNext account, which includes monthly AI credits. In the app you can also save sets as hashtag groups and add them from the composer. The hashtag checker on this page is free and works in your browser.
