==PageRank Algorithm==

Perhaps the most innovative contribution Google has made to internet searching is it's '''PageRank''' algorithm. This system works by counting the number of sites that link to another site; the more links pointing to a page, the higher that page will be ranked. The engine also takes note of how often the page is updated. Due to this, [[Wikipedia]] is consistently ranked very highly by Google, due to it's constant updating and heavy linkage. More recently, internet-savvy Googlers have discovered ways to game the system; creating massive numbers of pages with links pointing to one page form what is known as a "Google Bomb". Some examples can be found below.
