I am wanting to build a "mini net". For simplicities sake lets say I had 3 mini authority sites as part of my tier 1 with 25-50 articles on specific niche related topics pointing to different pages of my money site. I know that you'd want to put them on different hosts to have different c class ips, name servers, rdns, and I guess private Whois as well. Anything I'm missing? Would it be pretty stupid to put adsense on the tier 1 mini authority sites since that adsense Id would be a way to identify me as the owner of all sites? I may have Answered my own question here... I just want to know if anybody has any experience with this. Either way I'm interested in building these mini authority sites. Am I better off if I want to put AdSense on the mini authority sites to not link them out at all to my money site and just have them as separate individual sites or not use adsense at all on the authority sites and use them strictly for back linking the money site and increasing their authority? I hope I've been clear. Thanks in advance.
