Effective SEO requires a basic understanding of how the pieces of search engine technology fit together.
A search engine, such as Google, implements four basic mechanisms:
* Discovery, meaning finding web sites. This is accomplished using software that travels down web links, which is sometimes called a bot, webbot, or robot.
* Storage of links, page summaries, and related information. Google calls the systems used for this purpose its index servers.
* Ranking, used to order stored pages by how important they are. Google uses a complex mechanism called PageRank to accomplish this task.
* Return of results, used to organize the display of search results, based on ranking, in response to a specific user search query.
Discovery, Storage, Ranking, and Return (DSRR) are all important to SEO. In particular, you'll need to have a basic grasp of Discovery and Ranking in order to be effective with SEO implementationso these mechanisms are explained in greater detail later in this article ("Using PageRank").
