I have created 6 web 2.0 for tier 1 with each containing 5-6 articles(1-2 linking to my money site). I am planning to create 5 -6 tier 2 web 2.0 for each tier 1. I would like to know whether I should link the tier 2 to the article of tier 1 which links to my money website or to the main page (all posts appear on main page). Thanks!!
