What does keyword mean?
A keyword is a word or phrase used to identify, categorize, or find information, especially in a database, website, catalogue, or search engine. Searchers enter keywords to express what they are looking for, while websites and databases use them to organize and retrieve relevant material. The word can also refer more generally to an important term associated with a subject, idea, product feature, or marketing message. In programming, a keyword is a reserved word with a special meaning within the language. The term is useful because it emphasizes the role of language as an organizing tool: keywords connect a user’s concise description with stored information. Although “keyword” is sometimes used interchangeably with “buzzword,” it is more specific in technical contexts and does not necessarily carry the same negative connotation of empty or fashionable jargon.

Where does keyword come from?
“Keyword” is a compound formed in English from “key” and “word.” The combination developed from the longstanding idea that a key word is a word that serves as an index or means of access to information. Later, the term was extended to search systems, online content, advertising, and computer programming, where it denotes a significant or functionally reserved term.
