Hashtag Counter

Each platform says so itself. X's Help Center recommends no more than 2 hashtags per post as best practice, though you can use more. LinkedIn's own blog suggests no more than 3 per post so it doesn't look cluttered. Instagram's Help Centre says you can use up to 5 hashtags on a post. This tool shows a verdict for each platform based on your unique count. The sources are listed below these questions.

A broken hashtag is a '#' that isn't immediately followed by letters, numbers, or an underscore: for example '# marketing' (space after the hash) or '#!'. Platforms won't turn these into clickable tags. The counter flags them so you can fix the spacing or remove the stray '#'.

It counts both. The total includes every hashtag occurrence, while the unique count deduplicates case-insensitively, so #Marketing and #marketing are treated as the same tag. The Duplicates figure is the difference, so you can spot accidental repeats before posting.

Yes. Hashtags are part of your caption and count toward the character limit on every platform. If you're tight on space, use the Social Media Character Counter alongside this tool to see how much room your tags take up.

No. A hashtag ends at the first space or most punctuation, so '#social media' is read as the tag '#social' followed by the word 'media'. Hashtags can contain letters (including many non-Latin scripts), numbers, and underscores, but not spaces, hyphens, or emoji.
