Google launched its latest Panda update! Incase you didn’t know yet. Earlier last week, Google’s Panda 4.0 went live. What was the update about? In short, it was to filter out websites with lots of low quality content out of the 1st page search results. Panda 4.0 is not just a data refresh; it’s in fact a major update that changes how the algorithm identifies websites.
Panda was first made its appearance in February 2011 and has had multiple updates since. Panda 4.0 has since shown more or less impact for about 7.5% of queries in English. This is considered high and to a degree whereby the regular user might notice the difference. How Panda effects other languages differs depending on the individual landscapes.
