What Is a Search Engine? (Beginner-Friendly Explanation)

A search engine is a software system or website that allows users to search for information on the internet by entering keywords, questions, or phrases.

How a Search Engine Works (Step-by-Step)

1. Crawling
   Automated programs called crawlers or bots scan websites across the internet.
2. Indexing
   The discovered pages are stored and organized in massive databases called indexes.
3. Ranking & Displaying Results
   When a user searches, the engine ranks indexed pages based on relevance, authority, freshness, and user intent.

Without search engines, finding information online would be nearly impossible.
