Why? - Page Ranking

What is Page Ranking??

Simply speaking Page Rank is a 'election', by all the other pages online, about how exactly important a site is. A link to a page counts as a vote of support. There's no support (however it is definitely an abstention from voting rather than vote against the site) if there's no link.

How is Pr Used?

Pr is one of many techniques Google uses to ascertain a page's significance or significance. It's only one part of the story when it concerns the Google list, but the other aspects are discussed elsewhere (and are ever changing) and Pr is exciting enough to deserve a paper of its own.

Page Ranking can also be shown o-n the toolbar of your browser when you have installed the Google toolbar (http://toolbar.google.com/). However the Toolbar Page Rank only goes from 0 - 10 and appears to be something similar to a logarithmic scale:

Toolbar Site Rank:

(log base 10) Real Pr

0 0 - 1-0

1 10-0 - 1,000

2 1,000 - 10,000

3 10,000 - 100,000

4 so and on..

We can not know the exact details of the size since, as we'll see later, the utmost PR of pages on the internet changes every month when Google does its re-indexing! If we think the scale is logarithmic (though there is only anecdotal evidence with this at the time of writing) then Google could simply give a toolbar PR to the greatest real PR site of-10 and scale the others accordingly.

Also the toolbar sometimes guesses! The toolbar often shows me a Toolbar PR for pages I have only published and can't possibly be in the list however!

What appears to be occurring is that the toolbar looks at the URL of the page the browser is displaying and strips off everything down the last '/' (i.e. it visits the 'parent' page in URL conditions). If Google includes a Toolbar PR for that parent then it subtracts 1 and shows that as the Toolbar PR for this page. If there is no PR for that parent it visits the parent's site, but subtracting 2, and etc entirely around the root of one's site. If it can't find a Toolbar PR to display in this way, that's if it does not find a page with a genuine calculated PR, then a club is greyed out.

Note that if the Toolbar is betting in this manner, the Actual PR of-the page is 0 - the Google spider first sees it though its PR will be assessed shortly.

PageRank says nothing about the material or size of a page, the language it's published in, or the text used in the point of a link!

Meanings

I have started to use some shorthand and technical conditions in this paper. Be taught more about Fly Fishing - The Straightforward Art by navigating to our great website. Now's of the same quality an occasion as any to establish all of the conditions I'll use:

PR: Shorthand for PageRank: the actual, real, page list for each page as calculated by Google. As we'll see later this may 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 said to possess a 'backlink' from page A.
