Getting in trouble with Google by mistake

what happens when you go International

[iokubok]

Hi all,
I am just launching my website internationally and to be honest I have limited knowledge of organic listing on local search engines and directories. I understand the principle of having local domains but, I am worried about how multiple sites could be considered spam.

To set the scene my website is selling a large number of widgets (about 15,000) and there is little difference between each site apart from payment options for each country and a slightly different structure depending on which widgets are most popular in each country. Each site will also translated, into relevant languages. All site will be hosted on the same server in the US. The sites will also be linked to each other through one central domain.

I am mainly concerned about the effects of accidentally spamming google. Especially in English speaking countries like NZ, Ireland, Canada and Australia. I assume the chance of spaming none English speaking counties is reduced as the content is effectively different.

Also in instances where I am unable to get relevant local domains is the chance of spaming increased if I were to use a sub domains such as [ie.example.com...]

Could someone explain if this is a problem with google and any suggestion?
