Hello I make around 15-20 tier 2 links to each tier 1. What is more important make as many Tier 1 (web 2.0 blogs) or make as many tier 2 (web 2.0 profiles) I also do tier 3 (social bookmarking)? Because i make a lot of tier 2 for each tier 1, but maybe i need to reduce tier 2 and make and use these resources for more tier 1. Thanks !!
