What is a hashtag?

In the jargon of the internet and specifically of social networks, it is called hashtag or label to a clickable phrase or word, that is, a metadata tag that allows a user to access a specific set of entries (such as writing or images on a social network) that have been marked with that specific descriptor. Typically, this is a string of words and characters preceded by a pound or pound sign (#).

For example, a user of social networks (especially Twitter, Instagram, Facebook, YouTube and Telegram) can click on the hashtag #VeganRecipes to go to the entries identified with this content, thus filtering the vastness of available online content to go directly to what you are looking for.

It is also common for users of social networks to invent their own labels to express certain personal positions, emotional states, or ironize with the use of social networks itself. For example: #IHateMondays or #Anything.

For its part, the word hashtag It is a neologism from the English language (that is, an Anglicism) composed of two different voices: hashtranslatable as “numeral” (#), and tag as “label”. Each tag or hashtag represents a specific topic and a quick and easy digital descriptor for any database of microblogging.

Origin of the hashtags

The hash or pound sign (#) already it was part of the descriptive protocols of various online communications services from the late 1990s and early 2000s, such as Internet Relay Chat (IRC) or Jaiku.

It was used as an information descriptor, in a similar way to the keywords of library systems, but not with the exact meaning that it obtained from 2007, when it began to be used in the social network Twitter.

The first use of a hashtag on social Twitter was by Chris Messina, a Google worker.who proposed it to organize the entries (tweets or tweets) that belonged to the same group:

hashtag tweet tweet messina

The tweet translates to “How about using # (numeral) for groups, like in #barcamp [msg]?”. That same year, the use of hashtags became popular when another user on the same social network created #sandiegofire to tag his posts about the California wildfires in October.

Since then, the hashtags were used to group entries referring to the same topic, the same news event or the same debate among users of the social network, and it soon spread to other similar platforms such as Instagram, YouTube and Facebook.

In general, a hashtag must be:

  • A simple and short sentence, of few words, that alludes directly to the subject referred to. It must be headed by the pound sign or pound sign (#) and without spaces between the words that compose it: #ThisisunHashtag.
  • It is common to differentiate between upper and lower case (CamelCase) to distinguish one important word from the rest and make it easier to read. This is usually done with the initial capitalization of each word, but there are no definitive rules on this.
  • must be clickable (that is, a hyperlink), so that the user can navigate between the entries of the platform that are identified with the same label. The same entry can have several labels simultaneously.
  • The hashtags of greater diffusion and with greater visits enter a popularity ranking and are called Trending Topics (“Popular Topics”).
