Determining PR exactly ("exactly") :P

[Pegasus]

This is my method for determining the speed of my voyage through the vast land of PR6.

I go to my category of the Google Directory, and click to make the pages arrange in order of their Pagerank.

By visiting sites on the list, I find the lowest PR6 page on the list, and the highest PR6 page on the list.

There are 63 PR6 sites in my category. I am 35th on the list. (This doesn't mean I have ~PR6.5 though.)

In my category, from PR5 to PR6 to PR7, there seem to be 1/3 as many pages on one rung as on the rung below it.

I'm in the middle of my section - but most of the pages in the section are closer to PR6 than PR7.

Using various square-rooty calculations that I don't understand, this would indicate that being in the middle of the PR(X) list equals a pagerank of X.36

I'm slightly below the centre, so I'll give myself a ranking of about 6.3 :)

Pegasus.

I am not sure if you know of this: if you right click on the green part of the page rank bar next to your listing, and select properties you will get your page rank.

Page Rank is on a scale of 40.(Google.com ranks higher...?)

pos.gif = 32 pixels
neg.gif = 8 pixels

These two images combine to make the complete bar.
There is a more extensive article about this here:

The toolbar will only give you integer values, 4, 5, 6, 7 etc.

The approach of pegasus can in some cases give you an estimate on the first decimal of the pagerank - if the directory listing really is sorted on the non-rounded PR value.

nerdrank. the way to go.

In the results that get sent back to the google toolbar, what does the FVN part mean, and does this help you determine more information about the true position? Here's what you get for webmasterworld:

Rank_1:1:7 FVN_1:96:Top/Computers/Internet/Web_Design_and_Development/Authoring/Webmaster_Resources/Chats_and_Forums

I found this thread but FVN is still not fully explained [webmasterworld.com...]

Does that mean it's in the 96th DMOZ category?

I think you mighta missed something there colemanator.

I'm trying to determine an approximate fractional pagerank.

Anyone else got any ideas on getting a more exact pagerank?

You can get a fairly accurate PageRank reading by analysing the Toolbar reading for a group of interconnected pages if you know for sure what the link strcture is and that PageRank only enters into the structure from outside. It's much easier if the PageRank feedback loops are kept very simple or non-existent.

[colemanator]

Sorry for the brain fart, I see now. What are the benefits of knowing your fractional PageRank? Month to Month comparisons, etc?

[jomaxx]

How do you know that when you sort by pagerank, that Google sorts by EXACT pagerank? Maybe it just sorts by whatever simple number is used to derive the size of the green bar.

[ciml]

jomaxx, you don't need Google to sort by PageRank if you are able to follow the site structure (rare IMO).

> What are the benefits of knowing your fractional PageRank

Some people like to know how things work, and you need to isolate variables in order to study them. The Toolbar resolution is too poor for good experiments, but if you gather enough Toolbar readings from a simple enough site then you can create your own scale and study in more detail (but be warned, after you've spent a few months muttering to yourself about PR and various ranking aspects, people start to think you're rather odd).

[Pegasus]

Yes, the idea is to determine my standing from month to month.

It's a long way from PR6 to PR7, so it's nice to know I have PR6.3 :)

[colemanator]

You never really know if the three sites above yours have a higher PR or if they are tied with you...thoughts.
