What “hashtag” means

Wiktionary · Wikipedia

hashtag/ˈhæʃˌtæɡ/

  • nounA metadata tag, signaled by a preceding hash sign (#), used to label content.
  • verbTo label (a message) with a hashtag.
Full entry on Wiktionary →

A hashtag is a metadata tag operator that is prefaced by the hash symbol, #. On social media, hashtags are used on microblogging and photo-sharing services–especially Twitter and Tumblr–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 #flowers returns all posts that have been tagged with that term. After the initial hash symbol, a hashtag may include letters, numerals or other punctuation.

#hashtag across platforms

every network with a public tag surface

Follow #hashtag straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/hashtag
