Here are a few thoughts that come to mind:
Posting a few posts, creating blogs with little activity unless you are a recognized expert in some specific industry DOES NOT WORK with traffic building.
The type of strategies I used over the last couple of weeks generated more results that posting 50 trageted articles on a given topic and hoping that traffic will pick up.
In other terms, you can have amazing content and hope that public will find it, it usually won't work!
You need much more than that and when you focus on traffic building strategies, you need to think differently.
You need to CREATE SYSTEMS that generate that traffic!
This means that you might need automatization tools which are going to duplictae your efforts
+ Follow up on your strategies.
This is exactly the same whether you focus on BLOGGING SEO or BOOKMARKING SEO.
It takes much more than a dozen of incoming links to build traffic or score high in serch engines!
