Hi - I'm pretty new at this.
We’re running an e-commerce affiliate site at http://www.mydomain.com. So we don’t take payments but customer gets passed through to third party sites when they select to buy a product. We have a blog at http://www.mydomain.com/news.
I think Google is treating these 2 sites as as separate sites for PR. For this reason we're thinking about moving this to http://news.mydomain.com. Anyone have any experience in this?
