A hashtag is a metadata tag that is prefaced by the hash (or pound) sign, #. Hashtags are used on microblogging and photo-sharing services such as Twitter or Instagram as a form of user-generated tagging that enables cross-referencing of content by topic or theme. For example, a search within Instagram for the hashtag #bluesky returns all posts that have been tagged with that term. After the initial hash symbol, a hashtag may include letters, numerals, or underscores.

The use of hashtags was first proposed by American blogger and product consultant Chris Messina in a 2007 tweet. Messina made no attempt to patent the use because he felt that “they were born of the internet, and owned by no one”. Hashtags became entrenched in the culture of Twitter and soon emerged across Instagram, Facebook, and YouTube. In June 2014, hashtag was added to the Oxford English Dictionary as “a word or phrase with the symbol # in front of it, used on social media websites and apps so that you can search for all messages with the same subject”.
Pro Tip: Try not to use too many hashtags, this may alert a platform algorthium that the post is spam.
