A hashtag is a keyword or phrase used to describe a topic or theme, and is immediately preceded by the pound sign (#). Hashtags can help you find topics that interest you. For example, "dogs" could be a hashtag, and so could "border collie puppy training." One is a broad topic, and the other is a phrase that is specific.
