Use hashtags on Twitter

A hashtag—written with a "#" symbol—is used to index keywords or topics on Twitter. This feature allows people to easily follow topics they are interested in.

Use hashtags to categorize Tweets by keyword:

  • People use the hashtag symbol (#) before a relevant keyword or phrase in their Tweet to categorize those Tweets and help them show more easily in Twitter search. 
  • Clicking or tapping on a hashtagged word in any message shows you other Tweets that also include that hashtag.
  • Hashtags can be included anywhere in a Tweet.
  • 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 Tweet with a hashtag on a public account, anyone who does a search for that hashtag may find your Tweet.
  • Twitter recommends using no more than 2 hashtags per Tweet as best practice, but you may use as many hashtags in a Tweet as you like.
  • Type a hashtagged keyword in the search bar to discover content and accounts based on your interests.
