How to use hashtags

A hashtag—written with a # symbol—is used to index keywords or topics on X. This function was created on X, and allows people to easily follow topics they are interested in.

Using hashtags to categorize posts by keyword

  • People use the hashtag symbol (#) before a relevant keyword or phrase in their post to categorize those posts and help them show more easily in X search. 
  • Clicking or tapping on a hashtagged word in any message shows you other posts that include that hashtag.
  • Hashtags can be included anywhere in a post.
  • Hashtagged words that become very popular are often trending topics.

Tips for using hashtags
  • You cannot add spaces or punctuation in a hashtag, or it will not work properly.
  • If you post with a hashtag on a public account, anyone who does a search for that hashtag may find your post.
  • We recommend using no more than 2 hashtags per post as best practice, but you may use as many hashtags in a post as you like.
  • Type a hashtagged keyword in the search bar to discover content and accounts based on your interests.
