Change IP to help get unpenalised?

[papamaku]

I've been asked to help out on a friend's site that has been penalised by G (PR grey bar + homepage semi-indexed).

There are a number of things that i'm planning to try - many site changes and inbound link changes. However someone has recommended to me that the first step should be to change the site's C Class IP, but surely the penalisation follows the domain name, not just the IP.

Any thoughts?

Class C IP neurosis is one thing you will hear on this board that I used to subscribe to and no longer believe in. Google determines link clusters by cross linking, NOT IP address, nor whois info.

I tested this on a large scale.

Yes, i believe it would follow the domain name in addition to many other factors. Of course with a new domain name you're looking at the sandbox,which is financially the equivalent to being banned. If you have cleaned up the offenses which caused the penalty in the first place (and made doubly certain there are no more) you can send an email to [e-mail] with Reinclusion Request as the subject line. I have no idea if this would help you avoid the sandbox, but we're all hoping this will be a thing of the past in the near future.
