Free Hashtag Checker
Tell us what the video is about, paste your hashtags, and get a 1 to 100 score with the issues holding your set back and a suggested replacement set. No signup needed.
Discipline beats volume
When we calibrated our scoring rubric against real high performing and low performing YouTube videos, hashtags showed one of the clearest patterns: walls of spam tags scored low and predicted weak performance, while small, disciplined sets of relevant tags tracked with videos that did well. Hashtags work by telling the platform what your video is about. Twenty unrelated tags do not amplify that signal, they destroy it.
The checker looks at your set the same way: does each tag match the video, does the set mix broad reach with niche precision, and is the count sensible for the platform.
Hashtags are one of seven scores
The full Uploadworthy analysis uploads your actual video and scores your title, description, hashtags, thumbnail, video pace, audio, and hook strength in one pass, each with reasons and fixes. It can also write your packaging for you from the video itself.

Frequently asked questions
›How many hashtags should I use on YouTube?
Three to five relevant hashtags is the sweet spot on YouTube. The platform only shows a few above the title, and walls of tags read as spam to both viewers and the algorithm.
›How many hashtags should I use on TikTok and Instagram?
Five to eight focused hashtags outperform giant blocks on both platforms. Mix one or two broad tags with several niche tags that match exactly what the video shows.
›Do hashtags actually help views?
They help discovery at the margins, mostly by telling the platform what your video is about. Irrelevant or spammy tags can hurt by confusing that signal. Discipline beats volume.
›What counts as a bad hashtag?
Tags unrelated to the video, generic tags like #fyp used alone, duplicate meanings, and trend tags used purely for reach. The checker flags each of these in your set.
›Is the hashtag checker free?
Yes. You can run several checks per hour with no account. A free account adds the full video analysis where hashtags are one of seven scored metrics.
