Google PageRank is an important part of SEO especially in link building. PageRank can scale the value of the link. Most of us will do link exchange or one way link, so they will check the link value. And do you know how to calculate the score of PageRank? There is one formula which can do some help for you.



Where:

RS = RelevanceScore: (Score based on keywords appearing in Title, Meta tags, Headlines, Body text, URL, Alt text, Title attribute, anchor text etc. of your site)

PR = PageRank: (Score based on number and PR value of pages linking to your site. Original formula is PR (A) = (1-d) + d (PR (t1)/C (t1) + a+ PR (tn)/C (tn)), where PR of page link is the sum of the PR of each page linking to it divided by the number of outgoing links on each of those pages. C is a dampening factor believed to be equal to 0.15)

LS = LocalScore: (Score computed from expert documents. Has variables and different values for search term appearing in title (16), headline (6), anchor text (1), search term density etc. Figures in parenthesis are the original values, which may have been changed by Google)

a, b, c = Tweak Weight Controls: (available to Google for fine-tuning the results)

d, e, f = Dampener Controls: (available to Google for fine-tuning the results. We believe that the value of a is currently set at zero.)

fb = FactorBase: (The PageRank scale of 1 to 10 on Google bar is not linier but an exponential/logarithmic one. As per our internal analysis, we believe that it is a base close to 8. This means that PR5 is 8 times more in value than PR4. As such, a PR8 website has a value 4000 times more than a PR4 website. This factor somehow needs to be built into the algo formula. We have therefore taken a fb value to accommodate this factor)

you have valuable information regarding SEO .

Hi, I convey my thanks to ur valuable information.

PR is not as important as it used to be. Still it is valued as a big factor in SERPs. It is basically a value to see how important or popular a page is in the eyes of google.

Page Rank is a link analysis algorithm used by the Google Internet search engine that assigns a numerical weighting to each element of a hyper linked 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).

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.[citation needed] In order to prevent manipulation, spoofing and Spamdexing, Google provides no specific details about how other factors influence PageRank.[citation needed]

Numerous academic papers concerning PageRank have been published since Page and Brin's original paper.[4] 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.
