In addition, digital marketers use hashtags to convey information to the target audience. In this article, you will learn how hashtags work in different social media networks.

Facebook Hashtags

Facebook supports hashtags created using letters, numbers, and underscores. Other characters are placed outside the label.


If you click on the hashtag or enter it into the search box, posts with the appropriate label will appear in the feed.

  • To keep messages from looking spam, use no more than three-four tags for each post;
  • Include your business name or keywords in a hashtag;
  • Do not use popular hashtags that are not related to the content of your posts - this is not hijacking, this is spam!
