How Search Engines Work

You may ask the question, how does a search engine find other pages to index?
The answer is in links.

1. A search engine sends out a "bot" or "spider" and crawls your pages. After it has indexed one page, it will look for a link on the page. Then they will follow into the link and index that website also. The cycle keeps going on until a page has no links. Then the search engine will start from a random site that they have already indexed and starts crawling again.

2. After a search engine indexes a page, the information goes into a very big database containing infromation from the website. These pages are very precisely recorded so that when a user sends a query, they can locate the information in a fraction of a second.

3. A Query is a request for information from a search engine. The search engine will then match up with their database and see if there are any pages that are relevant. Sometimes, Search engines remove words such as "and", "if", "is", and other common words.

4. The search engine will rank the pages by relevance and popularity and other SEO factors. Once everything is sorted out, the search enginewill send them to the browser (of course they will not send all 30 million results at the same time).
