You have most probably stumbled upon one or two hashtags while using social media. The microblogging service, Twitter, launched the popular keywords in 2007. Alongside Twitter, the pioneer of keyword search is Instagram, a photo sharing service that has since been purchased by Facebook. Since a tweet on Twitter must not exceed 280 characters (it used to only be 140 characters), Twitter hashtags offer the ideal way to group short tweets depending on their topic. In order to identify content, such as photos and videos that are shared, as well as enabling written communication, hashtags have become fully established on Instagram as well. In addition, users use hashtags to create an emotional reaction to a post.
The term 'hashtag' is a combination of the word 'hash' and 'tag'. The hash is, of course, the '#' symbol, and tag refers to the label that is given to the content. Hashtags enable you to filter information quickly and precisely, as well as identifying and tracking current trends and topics.
