How do search engines work?

A search engine is a giant database of internet sites and pages. A search for the keyword ‘Monopoly’ on Google will search their entire database and return a list of websites that mention ‘Monopoly’ in order of relevance.

A search engine such as Google will judge a site’s relevance according to a wide combination of criteria. I will use extensive and detailed knowledge of these criteria to optimise your website to become as relevant as possible.

The majority of internet search engines (Google included) use automated software ‘spiders’ to collect sites for their listings. Search engine ‘spiders’ crawl the internet looking for websites that meet their criteria for inclusion in their databases. The Yahoo! Directory differs from the majority of search engines in that a member of the Yahoo submissions team checks all websites that are submitted before they can be included.
