The function of a search engine in the context of the internet is to enable users to locate information swiftly and effectively. Search engines employ algorithms to index and rank web pages based on relevance to user queries. When a user inputs keywords, the search engine processes the request and retrieves relevant results from its database, often displaying them in an organized format. Effective search engines utilize techniques like search engine optimization (SEO) to improve visibility and enhance user experience. They are essential tools for navigating the vast landscape of online information.
