Search engines catalog sites and rank them based upon content, user friendliness, and other factors. You most likely knew that already, so below's a better question: "How do they do it?" Think of it as a house inspector who comes by after a major renovation of your house; he identifies if the job was done properly.
The same idea relates to search engines and their technique of indexing, except that instead of house inspectors, they're referred to "spiders." Search engines release these search engine spiders, sometimes called "crawlers," into the websites, not to wreak havoc but to check out your website and assess its content prior to indexing it for search engine users to see. Getting seen by spiders may be undesirable in reality, but it is a necessity for business Internet marketing.
These virtual spiders work day and night, walking all around the Net (which appears to bolster the idea of the crawlers being spiders). By crawling through a website, they gather up relevant information which includes the appropriate keywords to be connected with each and every web page. After gathering information, the spiders create an index built upon their programming.
There's no specific figure as to the number of search engine spiders there are, but Google's developers Sergey Brin and Lawrence Page are happy to discuss how fast they do the trick. Four spiders can crawl over 100 pages per second, and each crawler can keep around 300 websites open each time.
