google cache problem?

can google cache cause a problem with yahoo ranking or penalty?

[enotalone]

i have a problem in yahoo as many of do that the site even though in yahoo wont show up even for company name search. i have contacted yahoo few times, never got a straight answer what the problem is, but they gave few hints like the site is a directory which usually do not rank well in yahoo, domain.com and www.domain.com being duplicates... etc.

anyway, all this and everything else that i though might have been a problem are fixed now and i am thinking can google cache cause a problem with yahoo? google cache creates multiple copies of your site many domains, like alexa and others and this might confuse yahoo to think you serve duplicates. what do you think? i also noticed webmaster world has google noarchive meta tags when u are not logged in.
