Panda 4.0 was official released May 20th. It is designed to push down thin or low-quality content sites in the search results. It is still too early to see what is happening. Based on the data that is coming out at this point, Panda 4.0 looks to be a major algorithm update and NOT a simple data refresh. This means Google has made significant changes to how it identifies sites. If you do not have an SEO agency to audit your site and content, you should. Your web site rankings could dramatically decrease if you’re not careful! Clearly, Panda 4.0 is major update to the Google algorithm and is not a much smaller data update. Google has implemented 24 data updates since Panda was launched on February 24, 2011. As with all major updates it takes some time to flush out what exactly is going to be impacted both negatively and positively as the algorithm is very volatile right now and should stabilize in the coming weeks so you can identify baselines and trends to correct.
