Hashtag
A hashtag is a label preceded by the # symbol that identifies or groups content on services that recognise it. It can represent a topic, campaign or conversation
What it means, how it is used and where it comes up, with its related concepts.
What it is and how it works
How it works and how useful it is depend on the platform. No number of hashtags universally improves reach. The selection should aid understanding and discovery without overloading the message. For tags containing several words, readable formatting helps convey their meaning and reduces ambiguity.
