Say I wanted to set up a dozen sites to do with niche X, the idea being to create a mini interlinking network, to help with search results. Now each site would have its own domain name, but would all be hosted on my same account - so they would have the same IP address. Are the search engines going to recognize that I own these 12 interlinking sites and bitch slap my SERs for it, or does it matter that they will be all on the same IP address?
