What is Search Engine?

A search engine is a software system designed to carry out web searches, allowing users to query the internet for information. It’s the backbone of how we find information online, with Google, Bing, and Yahoo being prime examples. At its core, a search engine collects data from the web, indexes it, and retrieves it when a user submits a query. The primary benefit? It helps you find relevant information quickly and efficiently.

How Does a Search Engine Work?

Search engines work by crawling the web, indexing content, and ranking it based on relevance and authority. They use complex algorithms to analyze keywords, metadata, and site structure. When you enter a search term, the engine scours its index to deliver the most relevant results.
