A hashtag is a specific word or phrase that helps categorise content within a specific platform. Any phrase that is intended to perform such a task should be preceded by a hash tag, which is simply the # sign. Hashtags function on almost all social networks, namely Facebook, Twiter or Instagram. In the first case, they are of little importance, while in the other two they have a positive impact on the reach and engagement of fans.
Hashtags often become strategic elements of marketing or social campaigns. This is primarily because they make it easy for users to find content on topics that interest them. Catchy hashtags are easy to remember and posts containing them can reach larger audiences.
