SEO in an acronym for Search Engine Optimization, which is the process of improving a web-site's profile by carefully building and configuring the site to be correctly indexed by the robots that Google™and the other search engines use to index the World Wide Web.
There are many ways in which a site can be optimized for SEO.
Search engines, like Google™ and Microsoft's Live Search™, include small programs, known as search bots (Search Robots), such as Googlebot, that trawl the web constantly, indexing each web-site that they find. They are also know as Web crawlers, Web spiders and Web robots.
These search bots are basically algorithms - or programmed rules - by which sites are assessed and added to the huge databases that these companies maintain.
By understanding something of the mechanism by which they work, pages can be built that are placed higher up the lists of results, that are returned by searches on certain keyword lists. To get some idea of how mathematically complex these algorithms are, try reading this page on Google's Page rank explained at WebWorkshop. -
