A Very strange situation with Google, any ideas?

I've noticed a very huge difference in google search results

[PoweredP]

My site is old enough - about 3 years. Had rated top by google in most commonly search phrases. It's hosted on a dedicated server in USA.

Right now I'm losing sales, but the average traffic remains the same. I've used few different proxy servers and noticed that site lost it's positions for some countries, e.g. US, Canada. Otherwise I've get some top positions for other countries, e.g. UK, India, Australia, etc.

24K pages on my website is indexed by google, PR=5, about 900 inbound links, website language is English, updated almost every day.

One more thing, I had to change my domain name to a new one. I've created 302 redirect and more then 2 weeks everything was nice.

Is someone has any ideas what's wrong and what's going on with google?

Thank you

Welcome to the forums, PowerdP.

How long ago did you change domain names? That date is the actual age of your site, not the date you first published your content. I'd guess that's the source of any troubles you are seeing, rather than proxy servers.

Also, a 301 [Permanent] redirect, rather than a 302 [Temporary], is the recommended action to send traffic from the old domain to a new domain.

302 redirects are simply poisen; that has been my experience, at least with Google.

As tedster recommended, use a 301 instead.
