How Search Engines Work
Search engines follow three major steps:
1. Crawling
Search engines use bots (also called spiders) to discover web pages across the internet.
2. Indexing
After discovering pages, search engines store and organize them in their database.
3. Ranking
When users search for something, search engines analyze thousands of factors and display the most relevant results.
