Description: A keyword is a significant word or phrase used in queries to filter data. In the context of database queries, keywords allow developers to specify which data they want to retrieve from a data source, thus optimizing communication between the client and server. These keywords are fundamental for defining query, mutation, and subscription operations in various data retrieval systems, facilitating the retrieval of precise and relevant information. In behavior-driven development (BDD), keywords can be used to describe scenarios and expected behaviors in a language that is understandable to both developers and non-technical stakeholders. In SEO, keywords are essential for improving a website’s visibility in search engines, as they help identify the terms users are searching for, allowing content creators to optimize their pages to attract organic traffic. In summary, keywords are powerful tools that enable effective communication and optimization across various fields of technology and web development.
