I was doing well until the big update last year. I was using GSA ranker to create my tier 1 sites and i get hit really hard! So I decided to take a different approach, I created around 100 web 2.0 sites manually with unique content, along with images and videos and 1 to 2 links pointing to authority sites, it took about 2 weeks to get done. My second tier I created 300 web 2.0 sites pointing to my 1st tier using UD and fiverr, I used GSA Ranker as my tier 3. Most of my keywords are in the top 5 and holding steadily.. Learn the system, before the system take you under!!
