Hashtags were first created by an early Twitter user as a way to keep up with new abbreviations and trending phrases. While they were originally implemented into the Twitter platform, hashtags can now be used across a wide variety of social media sites. The proliferation of hashtags is truly incredible. What began on Twitter has now spread to Facebook, Google+, Instagram, Google search, and almost everywhere in between.
In short, a hashtag is a word or phrase that is preceded by a number sign, in the form of #keyword. Hashtags are commonly a single word, something like #marketing, but sometimes they can be comprised of an entire phrase, like KitKat's #HaveABreak.
When you're using hashtags in your content, you're identifying the most important and popular keywords to highlight. Users are able to search through social media, both on individual platforms and on third-party websites which scan many different news streams, and find you or your message by the hashtags you've associated with it.
Two types of hashtags
There are essentially two types of hashtags: those that consumers can identify with your brand, and hashtags that are currently trending.Hashtags which represent your brand are the ones you should be focusing on in the long-term. These are phrases that should be highlighted on a regular basis in your posts and tweets, and will serve as the foundation of your hashtag marketing strategy.
Trending hashtags are phrases that are really popular on social media and have the possibility to bring you a lot of online profile in a short period of time. While Twitter provides the most popular hashtags directly on its site, other websites like Sprout and Trendsmap can make it easy to find out what words and phrases are trending across various different social media platforms. It's important to keep it relevant. Make sure your hashtag is related to your post content. Using one or two keywords and phrases in your posts is acceptable, but refrain from putting too many in there at once. Not only does this take away from the content you’re actually trying to promote, but it can also push consumers away who see the practice as unprofessional.
