Has anyone experienced a drop in keyword rankings for multiple websites lately? I have had my website drop to page 3 for main keyword, and page 2 for secondary keywords which hasn't happened since Feb 2011. Also, my clients websites have been either stagnant or dropping results to pages 4-9 for keywords that they were previously ranking for. My linkbuilding methods have been Tiered linkbuilding with Manually created Web 2.0 blogs, social signals (Twitter & Google + posts), 1 Youtube video, and 1 Press Release through PRweb.com. Then I use SEnuke and GSA to create Tier 2 links to the Tier 1s. This method was working great up until rankings started to drop in early June. (Right around Penguin 2.0 in late May). Has anyone else experienced the same thing? Anyone know if Tiered linkbuilding doesn't work anymore, I Heard that High PR blog posts from Private link networks are whats really working. I also heard that using the Rel=author tag with Google + works alone. Thanks for the help!
