Search Engine Optimization 101 - Page Rank
The whole point of Search Engine Optimization, or SEO, is to improve your web site’s ranking; that is to move it up in the list of search results so that it is as close as possible to the top. Many users will look no farther than the first page of search results and some will only look at the first two or three. Therefore, the higher you rank the higher your number of web site visitors.
Search engines like Google, Microsoft and Yahoo use very sophisticated algorithms to rank web sites. The most famous algorithm is Google’s PageRank. The name PageRank is a Google trademark and the process is patented by Stanford University where it was developed by Google founders Sergei Brin and Larry Page in their paper, The Anatomy of a Large-Scale Hypertextual Web Search Engine.
In a nutshell, PageRank assigns a value to each page based on the other pages on the internet which link to that page. A link to your page by a higher valued page will increase the ranking of your page. In other words, it’s not just what you know but who you know. The idea is that your page has more credibility if it is referenced by other credible sites, especially those sites which are relevant to the keywords used in a search.
