Is this arrogance on G's part or what?

How in the hell can Yahoo have a drop in PR to PR9?
I find this laughable.

[bobmutch]

mikeb: There were pages added to the index and this moved the PR10 scale up and the 37 of the bottom PR10's dropped down to PR9's. Google also have 7 pages that were PR10's drop down to PR9's. Check out my PR 10 Pages (http://www.seocompany.ca/pagerank/pr-10-pages.php) and you will see a what pages dropped out.

Its not personal you know, the PageRank assigned is purely mathematical (its a beautiful formula in fact). If yahoo's PR drop its due to particular factors. Yahoo would be treated the same as any other site.

I think this is partly because Yahoo keeps adding ton of pages and they are all visible to Google. PR kind of spreads around and top domain loses PR10 from time to time. This is just my wild guess though ...

[powerofeyes]

There is nothing to laugh, Yahoo is treated the same way any other site is treated in PR algorithm, If yahoo's homepage drops in pagerank it simply means it doesnt have the sufficient links any more to make the homepage a pagerank 10,

Many pagerank 10 pages did loose their pagerank and yahoo is one of them,

Yet Google remains PR10. Guess they haven't added any pages
:p

I still find it quite remarkable

In case you missed, according to Google Directory, Google http://www.google.com/ has PR11; http://directory.google.com/Top/Computers/Internet/Searching/Search_Engines/Google/. See how Froogle has PR10 AND Google's green bar, right above that, is longer?

Google - 16 outgoing on homepage, all to internal pages.
Yahoo - 262ish outgoing links on homepage, all internal

In theory yahoo is a pr10 site with so many incoming links, however they are spreading their pr out over lots of pages. Looking at most of its internal pages they too have a lot of links on each page.

Conclusion - yahoo is more interested in having useful navigation and services for visitors than a pr10.

How do you find these PR10 sites?

[bobmutch]

arius: There are about 6 or 7 good lists of PR10 sites on the internet. I collected all the pages listed in those sites and then by hand when though most of the main pages of those sites by hand, and compiled my list.

Well here's a quote for you:

"Markcarey: Are the ODP and Google sites naturally occuring PR10 (PR11 for Google?) or is there some manual intervention for larger sites to ensure they have suitable PR?

Googleguy: It’s all natural. "

And the way that this can be reinforced is that Google isn't the only PR11 page out there:

Adobe (http://www.adobe.com/enterprise/accessibility/main.htm)
Macromedia (http://www.macromedia.com)
Real (http://www.real.com)
Hotmail (http://www.hotmail.com)

(thanks to Chris R for the list)

The green bar is 44 pixels long for these sites so PR 11. The total bar length is 44pixels, so 44/11 is 4 per count.

(pr0=0pixels
pr1=4pixels
pr2=8pixels
pr3=12pixels
pr4=16pixels
pr5=20pixels
pr6=24pixels
pr7=28pixels
pr8=32pixels
pr9=36pixels
pr10=40pixels
pr11=44pixels)

All the other PR10 sites out there are actually Greater than or equal to 10. A PR0 is in fact greater to 0 but les than 1.

Remember thought that the Toolbar is just an approximation of PR.

Be sure that this is logarithmically calculated. Remember that the command in any search engine is not accurate for finding out what links in. In fact its near enough impossible to find out globally. Remember that Google own the directory though and then maybe things fall into place.

Xan: And the way that this can be reinforced is that Google isn't the only PR11 page out there: Adobe Macromedia Real Hotmail (thanks to Chris R for the list) I am guessing this list is from a 2 year old thread off webmasterworld.

None of the following are PR11 or GD 44s.

access.adobe.com is redirected to "http://www.adobe.com/enterprise/accessibility/main.html" (I think you left the "l" off in the html) and is a toolbar PR10 and a GD 38/2
"http://dir.google.com/Top/Computers/Software/Word_Processors/PDF/"

"www.macromedia.com" is a toolbar PR10 and a GD 38/2
"http://dir.google.com/Top/Computers/Multimedia/Software/"

"www.real.com" is a toolbar PR10 and a GD 38/2
"http://dir.google.com/Top/Computers/Internet/Broadcasting/Software/"

"www.hotmail.com" in the google directory is a 32/8
"http://dir.google.com/Top/Computers/Internet/E-mail/Free/Web-Based/H/Hotmail/"

The green bar is 44 pixels long for these sites so PR 11. The total bar length is 44pixels, so 44/11 is 4 per count. I am only aware of one GD 44 and that is toolbar PR10 "www.google.com"
"http://directory.google.com/Top/Computers/Internet/Searching/Search_Engines/Google/"

(pr0=0pixels pr1=4pixels pr2=8pixels pr3=12pixels pr4=16pixels pr5=20pixels pr6=24pixels pr7=28pixels pr8=32pixels pr9=36pixels pr10=40pixels pr11=44pixels) There are no 4px, 8px, 12px, 20px, 28px, 36px or 40px in the GD. There are cleardot.gif, 5, 11, 16, 22, 27, 32, 38 and 44.

This is the way Ridings matches them up. (This is my graphics by it follows Riding's divisions.)

http://www.seocompany.ca/images/gd-tb.gif

Below shows the graphic from Sobek's article matching the GD and toolbar PR scales up. Ridings holds to 8 units in the GD PR and 11 in the toolbar PR. Sobek holds to 7 units in the GD PR and 10 in the toolbar PR. (This image is a direct link to "www.miswebdesign.com.")

Remember thought that the Toolbar is just an approximation of PR. I subscript to the theory that toolbar PR is not approximation of real PR but that each unit in the toolbar displayed PR scale represents a section of the full range of real PR.

Be sure that this is logarithmically calculated. If you mean that the units in the PR display scale follow a logarithmical scheme, I agree.
