I happen to host in Hong Kong, but much of my target market is in the US. I have noticed, particularly since the Farmer/Panda update, that there are massive swings in SERPs for my keywords depending on which Google us being used to search.
Example: Google.com.hk (Hong Kong), pos #3; Google.com (no VPN), pos #16, Google.com (with VPN, USA location) not even in top 100.
No difference when logged into Google or not.
What is going on? How is it possible for hosting to have that much of an impact on search results -- could Google be that stupid? Assuming that the location of hosting is also the location of the target market?
Please tell me -- how do we set up our SEO so that we can rank in the US as well as in the local Google sites.
Appreciate the advice in advance.
