Page Rank Update Megathread (update 31.12.2009)

Aaron Wall is the authore of the excellent http://www.seobook.com and I have purchased it. It does NOT mention unique IP addresses in the book but its really a new thing and I have chat to him online and in forums before. I see John Scott got a plug, he was one the pioneers of this idea and he first made me confirm it with evidence (sadly hes taken that offline).

Aaron has never been wrong and like you guys hates myth and has written this website (now old) http://www.blackhatseo.com all about bad SEO. There has been so much bad information about SEO from “SEO professionals” (SEO is not a profession) its difficult to get new ideas out and I have to argue the points.

We could set up our own experiments (I only have 1 IP though) !?!

So far all I've heard is a lot of theories for both sides of the argument.
Admittedly by some heavy weights in the field.

I have yet to see one shred of evidence to support anyone!

One Experiment.
I have three sites all using a shared host with a common IP address.

Google search results for a very specific phrase that appears on all three pages, and lists only these three pages. (PR-4, PR-3, PR-4)

Site one has 130+ external links. Site two has 0 external links. Site three has 3 external links. Any other links come from the same IP address.

It may not be conclusive but to me it shows that links from the same IP have value when iy comes to ranking.

I have read about C block Ip theory before. but, getting many links from different sources will not be as difficult as mentioned. think abt it-

more expensive- how so?

Yes they have value no one ever said they dont and there are so many variables.

I guess I am going to have to go away and find some evidence.

It IS expensive, and time consuming to get outside links on MANY sites.

I must have contacted 20 webmasters for every link on my site. It does get better once you have PR to trade with.

It can take weeks or months to get enough links to start showing up in the search results.

lol. I thought the ultimate aim is to get links on many sites. on others sites, not yr own sites. so, it shld be as time consuming as before. isnt it?

These are the two papers that discuss devaluing links from the same IP block.

The question is can I prove it has been implemented! With so many variables its proving to be a bit difficult but I will work on it when I have time.

Anyone know how long it takes google to update the PR on the toolbar.

Once a month but... its taking over 4 months this time round and even with more than 4 good back links.

Dose that affect the search results???

Toolbar PR - hell no, its not even the real PR.

Back links and internal pages help loads!

google updates still not here yet

Lets hope it never happens

Gee .. I was hoping the updates would happen more often ... then I could see the results of all my hard work.

yeah man, same here.
