How search engines work.

the world most used thing ever.

The magic behind it all.

Search engines are not as complicated as you think first they have an empty index were they send out spider bugs that thin the pages and then likes that pages links and so on until the index is full then we you type a question like who dose Rooney play for in 0.5 seconds it looks through its index were it looks at if it has keywords in the title or in the URL or are next to each other in the main text and bang all the pages are rated and then put in quality order and appear before you.
