Hashtags are a really important part of Twitter. But what exactly is a hashtag? Simply put, a hashtag is any word or phrase included in a tweet that starts with a hashtag symbol (#), which you may also know as the pound sign or number symbol.
So why do people do this? When you include a hashtag in a tweet, you're basically categorizing that post. And if you select a hashtag, you'll see other posts that have used it. This is an easy way to see what's happening on Twitter and follow along with popular topics.

If you want to use multiple words in a hashtag, do not include any spaces. For example, if you wrote #beach sunrise, only #beach would be counted as a hashtag. Instead, you'll want to format it like this: #beachsunrise.
Hashtags are also an easy way to see what's popular—or trending—on Twitter, and to keep up with news and events in real time.
If you're using the Twitter app, you can select the search bar to see trending topics. If you're using a desktop web browser, you'll see these under the Trends section.
