Hashtags The Professor January 28, 2014 Professor's Tips Hash tag: on social media, a word or phrase (with no spaces) following a hash or pound sign (#) and used to identify messages on a specific topic. Hash tags are everywhere! #this #that #everything; some people are asking “What is that??” Basically, it is a way to “tag” something you have posted. Posts can be grouped together with other posts containing the same hash tag. So when someone searches a certain topic, only posts containing the particular hash tag will appear in the results. First it was mainly used on Twitter but is now used on Facebook and Instagram equally. There are no set hash tags, so you can be as creative as you like! Just make sure to leave out any spaces if you are tagging a phrase. So for those who have never used a hash tag before, you are now well informed and ready to go! #goodluck Leave a Reply Cancel Reply You must be logged in to post a comment.
