Search Engine Optimization - PageRank PR(E)

Most everyone that is making websites has a close look at PageRank and its importance to SEO. The world is controlled by Google right now (The World Wide Web anyways) and PageRank is actually a term created by Google.

Many people have spent incredible amounts of time trying to come up with formula that is used to calculate PageRank and some believe they have it pretty well figured out. In general terms, PageRank is an analysis algorithm which assigns a numerical value to each type of hyperlinked element in a document, specifically on the World Wide Web. The reason the PageRanking even exists is to assign an importance value or PageRank to the document being evaluated. The element is denoted as E, and the acronym for PageRank is denoted at PR, thus PR(E)
The PageRank Assumption: "The assumption that all the outgoing links in a Web page are followed by a random surfer uniformly randomly is unrealistic. In reality, links can be classified into different groups, some of which are followed rarely if at all (e.g., disclaimer links).
Such "internal links" are known to be less reliable and more self-promotional than "external links" yet are often weighted equally. Attempts to assign weights to links based on IR similarity measures have been made but are not widely used."

The Google Toolbar's PageRank feature displays a visited page's PageRank as a whole number between 0 and 10. The most popular websites have a PageRank of 10. The least have a PageRank of 0. Google has not disclosed the precise method for determining a Toolbar PageRank value,
As indicated on Wikipedia (which by the way has a PR 7)"The name "PageRank" is a trademark of Google, and the PageRank process has been patented (U.S. Patent 6,285,999). However, the patent was assigned to Stanford University and not to Google. Google has exclusive license rights on the patent from Stanford University. The university received 1.8 million shares in Google in exchange for use of the patent; the shares were sold in 2005 for $336 million." PageRank was created at Stanford University by Larry Page and Sergey Brin as part of a research project for a new type of search engine. They began in 1995 and led to a functional prototype, named Google, in 1998. Shortly thereafter, Page and Brin founded Google Inc., the company behind the Google search engine. There are many factors that go into the search ranking of Websites, PageRank will continue to be foundation for all of Google's web search tools for the foreseeable future until the next new thing.
