How to use hashtags

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

Using 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 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.
  • We recommend 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.
