Glad to hear the news on Serp Shaker. We haven't spoken before but I made 200k+ with Local Page Ninja!
Brian is talking about the predecessor to this plugin!
With Serp Shaker you no longer have to spend tedious, long hours building a single site, hoping it will start ranking 6 months down the road. You can build sites in multiple niches. When you find a niche/vertical that is generating the results you want...YOU ATTACK IT!
You keep building sites in that niche/vertical, while you look for and test other niches/verticals.
