Hi,

can any one guide me about what is a Page Rank model....and about Page rank Calculation method...

thanks in advance..

(Useless, overly manipulated metric + group of webmasters/SEOs who have no idea what it means) x web pages containing emotional, illogical rhetoric overstating its importance = not worth worrying about.

The calculation method varies. Despite the certain truth of ADAM's statements, Page Rank can make you money - and thus, you might be interested in learning more about it, no matter how contrived it is.

Generally, think about Page Rank like this: if your site is PR5 or more, you can sell static links on it (using services such as linkadage.com ) and make a bit of money - the more your PR, the more money you can charge

And of course the SEO world is screaming about sites who sell links having their PR cut. Google says not to sell links without using a nofollow or other method of preventing them from passing rank along.

In short PageRank is a “vote”, by all the other pages on the web, about how important a page is. A link to a page counts as a vote of support. If there’s no link there’s no support, it’s an abstention from voting rather than a vote against the page. The patented algorithm that Google uses to determine it's pagerank is:
PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

• PR(A) - Page rank of the target page
• PR(Tn) - Page rank for each page contributing towards the page rank of the target page.
• C(Tn) - Each page spreads its vote out evenly amongst all of it’s outgoing links. THis is the number of outgoing links from the contributing page
• d - Damping factor. All these fractions PR(Tn)/C(Tn) of votes are added together. To stop the other pages having too much influence, this total vote is “damped down” by multiplying it by 0.85 (the factor “d”). The (1 – d) at the beginning is a bit of probability math magic so the “sum of all web pages' PageRanks will be one”: it adds in the bit lost by the d(.... It also means that if a page has no links to it (no backlinks) even then it will still get a small PR of 0.15 (i.e. 1 – 0.85).

Google constantly modifies this calculation so don't take this as the definitive statement.

As to selling links:

If EVERYONE realised that PageRank didn't increase search engine ranking significantly or guarantee visitors, then links from high PR sites would be worthless unless they had a lot of visitors. People would finally wake up and realise that they are trying to get VISITORS, not PageRank. That is the ultimate goal of SEO.

Wait. Are you saying people only want PageRank to make their pages rank so they can get visitors?

I think there is a common misconception here, there appears to be a lot of hype about PR, but PR is Google's measure of site importance, it doesn't directly relate to search engine position or how much traffic/visitors come to a site. Learning Newbie is right people do need to wake up and concentrate more on SEO to attract visitors. Consider this, a high page rank site selling books can have few visitors, but a much lower ranking site can have more visitors, more visitors is more potential customers, is more real customers, is more income.

Learning Newbie is right that there is a misconception here and that PageRank isn't a good measure of a site's importance. He's also got it right that low PR sites can have much larger incomes than higher PR ones

I think the idea behind PR being a good measure of importance is sound. The more links a page has, the more important a resource it probably is. But importance is a generic measure. It isn't subject specific, whereas search queries are.

On the whole, the prime minister is an important figure (high PR - ha ha ha ha ha ha ha ha ha ha!), but he's possibly not the best person to ask about debugging javascript (the subject specific query).

Well, putting a "nofollow" into a paid link often defeats the purpose of the one paying. I agree - the ultimate goal is to get traffic, but if you have a small low-traffic authoritative site with a PR7, the reason why people would buy links on your site is precisely because of the PR benefits.

Yes but you're missing the point - if they realised that PR had very little affect on search engine rankings in the first place, they wouldn't bother with buying from sites to increase their PageRank - they would buy from sites to get traffic!

If everyone knew that PR was worthless, then they wouldn't pay large amounts of money to get it!

Could this be part of the reason why Google appears to start penalising sites that purchase links by reducing PR?

Not just part of the reason, more likely it is the reason

The reason Google is trying to prevent people buying and selling links that pass PR is because it does work to improve your ranking. If it didn't Google wouldn't care at all and the people who do engage in the buying insist it helps them rank.

Google hasn't really penalized anyone yet based on the reports I've seen. What it appears they've done is fire off a warning shot. It comes across as Google having manually adjusted the PR of some high profile sites that they believe are selling links.

Those sites seem not to be suffering any reduction in ranking or traffic which would be an indication that either PR has very little influence on ranking or that the adjustment has only been made the the visible PR we see in the toolbar and not the real PR behind the scenes or maybe a combination of both.

However, if PR has no effect at all on ranking there wouldn't be any reason for Google to want to prevent people buying and selling links that pass PR in the first place.

Page Rank = Bragging Rights

no real reward

links sellers who use High PR to sell more links are just taking advantage of the uninformed

My PR went up from 0 to 3, i appreciate the recognition from Google, but, I will focus on real SEO in order to reap real rewards

I would imagine if all guidelines were followed, and there were no loopholes PR would determine SERP, but that will never happen there will always be ways to cheat

Page rank increase when you have high number of people visits your site and it is recognize by Google .

No it doesn't.

"Google" has absolutely no idea how much traffic your site gets

PR is from links and NOTHING else

Listen to chrishirst PR has no effect on traffic, has no effect on visitors, has no effect on SERPs.

Does anybody really care what PR of a site is if the site is relevant to what the visitor is looking for? Let's stop getting so hung up on PR.
