What Are Search Engines?

A search engine is an online tool designed to help users find information on the internet. It works by crawling, indexing, and retrieving relevant content based on a user’s query. Search engines are essential in navigating the vast amount of data available online, providing organized and prioritized results for users.

How Search Engines Work

1. Crawling:
   Search engines use automated bots, called “spiders” or “crawlers,” to explore web pages and collect information. These bots follow links across websites to discover new pages.

2. Indexing:
   After crawling, the search engine stores the collected information in a database, called an index. The index is a massive library of web pages, organized by keywords and metadata.

3. Ranking and Retrieval:
   When a user enters a query, the search engine retrieves relevant pages from its index and ranks them based on relevance, authority, and other factors. This is done using complex algorithms.
