My issue is unique because of the way our website works and I hope that someone can provide some guidance on this. Our website http://breezi.com is a website builder where users can build their own website. When users build their site it creates a sub-domain route to their created site, for example: http://mike.breezi.com. Now that I have explained how our site works here is the problem: Google Webmaster Tools and Bing Webmaster Tools are indexing ALL the user created websites under our TLD and thus it is our impression that any content created in those sub-domains can confuse the search engine to thinking that the user created website content is relevant to OUR main site http://breezi.com. So, what we would like to know if there is a way to let search engines know that the user created sites content is not related to our TLD site. Thanks for any help and advise.
