Frequently asked questions
No account needed. Just enter your topic, pick how many hashtags you want, and generate. The whole thing takes about ten seconds.
YouTube recommends using no more than 3 to 5 hashtags per video. Going overboard (15+) can actually get YouTube to flag your video and ignore all hashtags.
You can add them in your video description, and they'll appear as clickable links. If you include a hashtag in the video title itself, YouTube highlights it too.
They help with discoverability in a limited way. Hashtags make your video show up when someone clicks or searches that tag, but they're not a substitute for a strong title, good thumbnail, and keyword research.
A mix works best. One or two broader trending hashtags can get you in front of a larger audience, while niche-specific ones connect you with genuinely interested viewers.
It's better to tailor them to each video. Using the exact same set repeatedly doesn't give YouTube much signal about what makes each video unique.
Yes. OneUp lets you schedule YouTube videos along with posts to Instagram, TikTok, LinkedIn, Facebook, Snapchat, and several other platforms.
