What is Google Pagerank? June 25, 2010
Posted by admin in : SEO , comments closedPageRank was developed at Stanford University by Larry Page (hence the name Page-Rank) and later Sergey Brin as part of a research project about a new kind of search engine. The project started in 1995 and led to a functional prototype, named Google, in 1998. Shortly after, Page and Brin founded Google Inc., the company behind the Google search engine. While just one of many factors which determine the ranking of Google search results, PageRank continues to provide the basis for all of Google’s web search tools
PageRank is based on citation analysis that was developed in the 1950s by Eugene Garfield at the University of Pennsylvania, and Google’s founders cite Garfield’s work in their original paper. By following links from one page to another, virtual communities of webpages are found. Web link analysis was first developed by Jon Kleinberg and his team while working on the CLEVER project at IBM’s Almaden Research Center.
PageRank is a link analysis algorithm used by the Google Internet search engine that assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of “measuring” its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E).
The name “PageRank” is a trademark of Google, and the PageRank process has been patented (U.S. Patent 6,285,999 ). However, the patent is 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.
Google describes PageRank
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 more than the sheer volume of votes, or links a page receives; 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”.
In other words, a PageRank results from a “ballot” among all the other pages on the World Wide Web about how important a page is. A hyperlink to a page counts as a vote of support. The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it (”incoming links”). A page that is linked to by many pages with high PageRank receives a high rank itself. If there are no links to a web page there is no support for that page.
Google assigns a numeric weighting from 0-10 for each webpage on the Internet; this PageRank denotes a site’s importance in the eyes of Google. The PageRank is derived from a theoretical probability value on a logarithmic scale like the Richter Scale. The PageRank of a particular page is roughly based upon the quantity of inbound links as well as the PageRank of the pages providing the links. It is known that other factors, e.g. relevance of search words on the page and actual visits to the page reported by the Google toolbar also influence the PageRank. In order to prevent manipulation, spoofing and Spamdexing, Google provides no specific details about how other factors influence PageRank.
Numerous academic papers concerning PageRank have been published since Page and Brin’s original paper.In practice, the PageRank concept has proven to be vulnerable to manipulation, and extensive research has been devoted to identifying falsely inflated PageRank and ways to ignore links from documents with falsely inflated PageRank.
Other link-based ranking algorithms for Web pages include the HITS algorithm invented by Jon Kleinberg (used by Teoma and now Ask.com), the IBM CLEVER project, and the TrustRank algorithm.
Improve Google PageRank NOW! May 31, 2010
Posted by admin in : Home Business , comments closedPageRank is a link analysis algorithm which was named after its creator – Larry Page. Google uses PageRank to determine the authority of any given website. PageRank often determines how high (or low) a website will rank in the Search Engine Results Pages (SERPs) for any given keyword.
Sites with relatively high PR often outrank those with low PR. While many SEO experts will debate that statement, don’t let them fool you, PageRank is extremely important when it comes to SEO, Google and Organic Search Engine Traffic.
In this post, I want to focus on the factors that determine the PageRank of any given website and how you can deliberately focus on those specific areas of your SEO campaign in order to boost your website’s PageRank to get more organic search engine traffic.
How Google Algorithm is Calculated
For many years, large numbers of internet Heroes, Warriors and Vikings have tried to conquer Google PageRank Algorithm. Many of them have tried to crack the algorithm’s code, but there is yet to be found a man who is capable of such an act of bravery.
Google constantly keeps changing the rules as soon as someone gets even close to cracking their data. However, overtime, great mathematicians have discovered an approximate way of how PageRank works:
PR(A) = (1-d) + d(PR(t1)/C(t1) + … + PR(tn)/C(tn))
In simple terms this equation can be translated into:
a page’s PageRank = 0.15 + 0.85 * (a “share” of the PageRank of every page that links to it)
*Share = The linking page’s PageRank is divided by the number of outbound links
Factors That Can Improve Pagerank
Check out the list of things that can improve your PageRank and help you rank higher in SERPs:
Update Pages Frequently. Google bots are constantly indexing your website. Keep your pages relevant and up to date.
Add Pages Frequently. Google recognizes fresh content as a good thing.
No Broken Links. Broken links are a disaster. It notifies Google that you don’t care about your website and therefore it doesn’t deserve Google’s respect.
Good Neighborhood Directories With High PageRank Levels. Submitting your site to relevant, high PR directories gives you valuable high PR backlinks.
Monster Websites. I have no idea what this means, just copied it from another trusted website.
Quality Inbound Links. PageRank is all about the quality. 10 links from a PR 5 website is far better than 100 links from a 2 PR site.
Quality Relevant Links. Relevancy is Key. Keep your link-building campaigns relevant to your sites theme.
Everything Put Together. All of these will result in a significant PageRank boost.
Avoid These!
Bad Inbound PPSD Links. PPSD=Poker, Porn, Sex, Drugs
Low Quality Content
Link Spamming
Black Hat SEO
High Volume of Broken Links
