Why - Page Ranking 48461

What's Page Rank??

Simply speaking Page Rank is a 'vote', by the rest of the pages on the Web, about how exactly important a page is. A link to a page counts as a vote of support. If there's no link there's no help (however it is definitely an abstention from voting rather than a vote contrary to the site).

How is Pr Used?

Pr is among the techniques Google uses to ascertain a page's meaning or importance. It is only one part of the story when it concerns the Google record, but the other aspects are reviewed elsewhere (and are ever-changing) and Pr is interesting enough to deserve a paper of its.

Pr can be shown on the toolbar of your browser if you have installed the Google toolbar (http://toolbar.google.com/). However the Toolbar Pr just goes from 0 - 10 and appears to be something like a logarithmic scale:

Toolbar Page Rank:

(log base 10) Real Page Ranking

0 0 - 10

1 10-0 - 1,000

2 1000 - 10,000

3 10,000 - 100,000

4 so and on....

We could not know the precise details of the size because, as we'll see later, the most PR of all pages on the net changes every month when Google does its re-indexing! If we suppose the scale is logarithmic (though there's only anecdotal evidence with this at the time of writing) then Google might simply provide a toolbar PR to the highest real PR page of-10 and scale the remainder properly.

Also the toolbar sometimes guesses! The toolbar often shows me a Toolbar PR for pages I've only just submitted and cannot possibly be in the catalog however!

What appears to be occurring is that the toolbar discusses the URL of the page the browser is displaying and strips off anything down the last '/' (i.e. it goes to the 'parent' page in URL terms). If Google has a Toolbar PR for that parent then it subtracts 1 and shows that as the Toolbar PR for these pages. If you have no PR for that parent it would go to the parent's page, but subtracting 2, and so on all the way up-to the main of your site. If it can not find a Toolbar PR to produce in this manner, that is if it does not find a page with an actual calculated PR, then the bar is greyed out.

Remember that if the Toolbar is wondering this way, the PR of-the page is 0 - after the Google index first sees it although its PR will be calculated shortly.

PageRank says nothing about the content or size of a page, the language it's written in, or the text used in the anchor of a link!

Explanations

I've started to use some shorthand and technical conditions in this report. Official Link contains more concerning when to mull over this concept. Browse here at the link logo to read the inner workings of it. Now's of the same quality a time as any to determine all the terms I'll use:

PR: Shorthand for PageRank: the actual, real, page position for each page as assessed by Google. If you think you know anything at all, you will seemingly hate to compare about How To IPod Your Car - VictorSky - Zordis for blogger. As we'll see later this can range from 0.15 to billions.

Toolbar PR: The PageRank shown in the Google toolbar in your browser. This ranges from 0 to 1-0.

Backlink: If page A links out to page B, then page B is believed to possess a 'backlink' from page A.
