So. I have a site. For arguement's sake we'll call it www.mikescrazysite1.com, and I am conducting a link building campaign for this site. Lets say I also own a second page which 401s over to the main domain and that page is called www.mikescrazysite2.com. If some glorious individual decides to link to mikescrazysite2.com, how will that link effect www.mikescrazysite1.com if at all?
