Number of changes requierd to distinguish between two pages

is there a magic "Formula" to be found

Hi all,
During my work a need for a few similar pages to be posted on different domain's/IP's came up.
The question is - How many changes must I make in order of keeping the pages distinguished from one another, and preventing them from being indexed as copies?

There is no magic formula, as far as I know. I've seen straight duplicates indexed & ranking for months on end, and I've seen duplicates get penalized from day 1 - or at least rank significantly lower...

My advice would be to create unique, useful content - as much seperation as possible between pages / domains. The real value will not be the search listings, but the amount of viral traffic, inbound links from folks, etc for your sites if they are truly interesting.

Hope that helps!
