Google confirming a Panda refresh on the 22nd Jan, and the mysterious update on the 15-17th makes two major updates over the last 10 days. I am a bit surprised that there is no discussion on the subject. Has anyone else been hit? I see a decrease across a large amount of projects that I am working on. I have the feeling google is getting on to the conventional SEO tools that the crowd is using? What do you guys think?
