A keyword is a word or phrase that describes the content of a document or web page. It is used to indicate the main topics or themes of the content, which can help search engines and users to understand what the content is about. Keywords can be single words or phrases and are often used in search engine optimization (SEO) to improve the visibility of content in search engine results pages (SERPs). By including relevant keywords in strategic places throughout the content, such as the title, headings, and meta description, it can help improve the content’s relevance and ranking for those particular keywords. Effective use of keywords is crucial for effective content creation, SEO, and information retrieval.
