What are Twitter hashtags? A common question received when individuals and businesses step into the world of Twitter, is what are hashtags? A hashtag is used to unite specific tweets about particular topics. It's a way of organizing or grouping tweets together. They are used to help tweeps (people who use Twitter) to find topics that are similar.
What does a hashtag look like?
It's the tweets you see that contain the "#" symbol plus a topic or word.
An example that comes to mind is this evening, while watching American Idol, many tweeps gathered together and united their post by including the hashtags #americanidol and #idol. This enabled the hashtags to be searched and allowed Twitter users to follow the conversation of others on Twitter regarding the popular American Idol show. The same was true during the last presidential election.
