If you’re a social media novice, hashtags — those short links preceded by the pound sign (#) — may seem confusing and unnecessary. But they are integral to the way we communicate online, and it’s important to know how to use them (even though some people, like Jimmy Fallon and Justin Timberlake, are not the biggest fans). Plus, they can be a lot of fun.
On Twitter, the pound sign (or hash) turns any word or group of words that directly follow it into a searchable link. This allows you to organize content and track discussion topics based on those keywords. So, if you wanted to post about the Breaking Bad finale, you would include #BreakingBad in your tweet to join the conversation.
