A hashtag, the # symbol, is used on Twitter to mark keywords, a phrase, or topics in a tweet. Hashtags categorize and group messages so that they show up more easily in a search. Clicking on a hashtagged word in a tweet will return all other tweets marked with that hashtag. You can include hashtags anywhere in your tweet, but they cannot include punctuation or spaces.
Some words and phrases are often hashtagged, while other hashtags are hardly used or only used by a small group of people. Commonly used hashtags can become Trending Topics, which appear on each Twitter profile, and therefore attract much more attention.
Using hashtags in your tweets, when appropriate, introduces your tweet to a new audience and can attract new followers, as well as giving you a glimpse into those users with whom you share a common interest. Joining in on conversations by using relevant hashtags allows you to engage with other like-minded Twitter users.
