What Is a Search Engine?

A search engine is a program or software designed to help users find information on the internet. By typing in certain keywords or phrases, a search engine displays results from various websites that are considered relevant to the user's request. Search engines work by indexing web pages, analyzing their content, and using algorithms to display the most relevant results on the search results page, or SERP (Search Engine Results Page).

How a search engine works involves three main processes:

1. Crawling: Search engines use bots or spiders to "crawl" web pages on the internet and collect data from each page.
2. Indexing: After pages are crawled, the data obtained is organized and stored in a huge database, so it can be retrieved and analyzed when users perform a search.
3. Ranking: Search engines use algorithms to determine which pages are most relevant to the keywords searched for, then display them to the user.
