What is PageRank?
PageRank is a patented method to assign a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web. Google runs on a unique combination of advanced hardware and software. The speed of google search we experience can be attributed in part to the efficiency of their search algorithm and partly to the thousands of low cost PC’s they’ve networked together to create a superfast search engine.
The heart of their software / search algorithm is PageRank, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University. And while they have dozens of engineers working to improve every aspect of Google on a daily basis, PageRank continues to provide the basis for all of our web search tools.
PageRank Explained
PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at considerably more than the sheer volume of votes, or links a page receives; for example, it also analyzes the page that casts the vote. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.” Using these and other factors, Google provides its views on pages’ relative importance.
Of course, important pages mean nothing to you if they don’t match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines dozens of aspects of the page’s content (and the content of the pages linking to it) to determine if it’s a good match for your query.
Google Toolbar PageRank
The Google Toolbar’s PageRank feature displays a visited page’s PageRank as a whole number between 0 and 10. Google has not disclosed the precise method for determining a Toolbar PageRank value. Google representatives, such as engineer Matt Cutts, have publicly indicated that the Toolbar PageRank is republished about once every three months, indicating that the Toolbar PageRank values are generally unreliable measurements of actual PageRank value for most periods of the year.
False or spoofed PageRank
While the Pagerank shown in the Toolbar is considered to be accurate (at the time of publication by Google) for most sites, it must be noted that this value is also easily manipulated. A current flaw is that any low PageRank page that is redirected, via a 302 server header or a “Refresh” meta tag, to a high PageRank page causes the lower PageRank page to acquire the PageRank of the destination page. In theory a new, PR0 page with no incoming links can be redirected to the Google home page – which is a PageRank 10 – and by the next PageRank update the PageRank of the new page will be upgraded to a Page Rank of 10. This is called spoofing and is a known failing or bug in the system. Any page’s Page Rank can be spoofed to a higher or lower number of the webmaster’s choice and only Google has access to the real PageRank of the page. Spoofing is generally detected by running a Google search for a URL with questionable PageRank, as the results will display the URL of an entirely different site (the one redirected to) in its results.
