Google announced earlier this month that their algorithm known as "Panda" had been rolled out for all languages. The change is said to impact between 6% and 9% of user queries, down from the 12% seen in the initial Panda update in February. Google had said in a blog post that "most users will see less than a 1% change." It turns out that wasn't exactly true. Mike Pantoliano explains the change to organic search traffic, and points to a bug in the original rollout of this change and how it makes a difference.
