Internet search engines (e.g. Google, AltaVista) help users find web pages on a given subject. The search engines maintain databases of web sites and use programs (often referred to as "spiders" or "robots") to collect information, which is then indexed by the search engine. Similar services are provided by "directories," which maintain ordered lists of websites, e.g. Yahoo!
To index a website, a search engine must first be told where to ‘find it’. Notifying a search engine of a new website is referred to as search engine registration. The registration process involves submitting an entry-level webpage address (URL), usually the address of the homepage or site map. Depending on the search engine, classification information may also be requested, such as a short description of the website, topics covered, and owner. Most public search engines have an ‘Add URL’ or ‘Submit URL’ link (often in the homepage footer) providing information on how to register a website. Once the website has been registered, the search engine owner runs an indexing program (spider). The indexing program follow hyperlinks from the URL(s) submitted to other webpages under the same domain, and in turn follows hyperlinks on those webpages, ‘crawling’ the entire website, to build a content index. Search engine optimization is a process or strategy designed to improve a webpage’s relevance ranking on a search engine result page (SERP). In the early days of the web, optimization involved carefully crafting metadata, setting up link farms and building reciprocal links to improve a website’s popularity―Google, for one, factors the number of links that point to a webpage (incoming links) into it’s relevance ranking (PageRank). Now, with the paid placement and submission fees to guarantee a listing, economics seem poised to triumph over content.
