Google Panda Update 3.9 Tonight

Google says it will roll out the latest update to its Panda algorithm later tonight.

The company posted the news a few minutes ago on Twitter, saying this update will affect about one percent of search results.

This is Panda Update 3.9. The previous update, 3.8, occurred exactly one month ago — on June 25th.

Google rolled out Panda initially in Feb 2011 and was designed to remove low-quality/thin content from Google’s search results.

Here’s what Google’s Matt Cutts had to say:

 “The goal of many of our ranking changes is to help searchers find sites that provide a great user experience and fulfill their information needs. We also want the “good guys” making great sites for users, not just algorithms, to see their effort rewarded. To that end we’ve launched Panda Changes that successfully returned higher-quality sites in search results.”
