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.

http://www.cs.toronto.edu/%7Egeorgem/hilltop/
http://patft.uspto.gov/netacgi/nph-Pars ... =6,526,440

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.

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

Back links and internal pages help loads!

When your competitors do a back links check they can do the same hard work in a matter of seconds. I hate Google (and others) for this because I had spend hours gaining relationships with other sites and exchanging links the good old fashion way.

If Google doesn't do a backlink update then you get no benefit from the additional PR.

Google only shows a few of the links to a site....
MSN and Altavista usually show links a lot sooner than Google does.

Anyway, it is far easier to scoop a site, and pick off only the best back links. :lol:

I think I would have to disagree. PageRank is update on the fly weekly/daily or hourly depending on the page being spidered. What you see in the back links update is Google making the back links public on that day. What you see in PR toolbar is Google making the results public. These updates day have no baring on ranking.

Be careful ....

Page Rank is only updated every 4 to 6 weeks. All you have to do is watch your new pages to see they don't get PR on the fly! :shock:

Search Engine Ranking on the other hand does appear to change more frequently. Sites tend to move up and down in the search results sometimes on an hourly basis.

Usually , after these updates is when you see sites move the most. That is why there is usually an uproar after a link update. The losers cry and the winners are cheering. :lol:

Maybe they aren't seeing any new content to crawl?

If your server supports HTTP headers they can see if a page has been updated without crawling the whole page.

What you see on the tool bar is the PR at the point of the last update.

I uderstand that the toolbar is not real ... in some cases it even guesses what the PR should be. That can be verified with the checksum tool.

But Google CANNOT calculate PR on a daily basis. In order to calculate properly, the PR of all incoming links has to be known. That means the entire Internet has to be calculated at the same time.

That is why it is only done every 4-6 weeks.

Google does a deep index and full update of PageRank every month or whatever, but it does also update some of the effects of some of the more powerful pages more frequently.

the temporary changes are likely just estimates, but still they do have an obvious effect.
