I found 6 deleted domains, that had PR/Dmoz or PR/yahoo directory and all had good active backlinks. I have a few question and any advice would be helpful. 1. How many domains is a good start, Im going after a few 3k search terms. 2. Should I make subdomains? Each domain will have a different c-class ip. 3. Should I make them pull RSS feeds from various news sites or anything to make them more natural? 4. I would like opinions on syndication. For example should I have sites syndicate posts to tumblr, wordpress, posterous and maybe twitter or facebook? Was thinking this might be the thing to do, but I would like to hear some opinions.
