Ok, I know for tier one high quality web 2.0 are very important. Good content on wordpress and blogger with your backlinks is very important but how do you build your web 2.0. Do you think it's better to make 1 blog with 15 posts or 15 blogs with 1 posts each. Do you add backlinks to every posts? Do you use your same wordpress account/blogger to make your many blogs? What else should be in tier one besides backlinks. Diversity is good for tier?
