Before we dive into the details of how search engines work, let's first understand what search engines are and why they are important. Search engines are online tools that help users find information on the internet. They work by indexing web pages and then retrieving relevant information when a user enters a search query.
Crawling
The first step in the process of how search engines work is crawling. Crawling is the process by which search engines find new web pages to add to their index. Search engines use automated programs called crawlers or spiders to discover new pages. These crawlers follow links from one page to another and index the content they find.
Indexing
After crawling a page, search engines index the content on that page. Indexing is the process of organizing and storing the content of a web page so that it can be retrieved quickly and easily. Search engines use complex algorithms to analyze the content of a page and determine its relevance to different search queries.
Ranking
Once a page has been crawled and indexed, search engines use a process called ranking to determine the order in which pages appear in search results. Ranking is the process of evaluating the relevance and importance of a page based on various factors such as keywords, links, and user behavior.
