How hashtag parsing works per social network

The following table illustrates how hashtags are parsed by social networks.

• Raw Text: The content a publisher would type when creating a post on that network.
• <Network> Parsed Text: The result after a piece of content is posted.
  • Instagram is the most lenient when it comes to detecting hashtags. Essentially, if there is a # sign anywhere, Instagram will detect or create a hashtag. #TrackMaven, Track#Maven, and#TrackMaven would all be acceptable (everything after the # would be included in the hashtag).
  • Twitter is slightly less lenient. It will not detect or create a hashtag if the raw text is in the form "Track#Maven." It does allow hashtags in the form#TrackMaven.
  • Facebook is the most strict. To create a hashtag, the # must not be preceded by anything, including text or an emoji. It must be in the form #MikeBernhard. Typing Track#Maven would result in that just being plain text.
