A hashtag is simply a keyword phrase, spelled out without spaces, with a pound sign (#) in front of it. For example, #InboundHour and #ChocolateLovers are both hashtags. You can put these hashtags anywhere in your social media posts: in the beginning, at the end, or anywhere in between.
To put it simply, a hash tag is simply a way for people to search for tweets that have a common topic and to begin a conversation. For example, if you search on #LOST (or #Lost or #lost, because it's not case-sensitive), you'll get a list of tweets related to the TV show.
