As explained in Wikipedia, Google Panda is a change to Google’s search results ranking algorithm that was first released in February 2011. The change aimed to lower the rank of “low-quality sites” or “thin sites“, and return higher-quality sites near the top of the search results. Google has posted a guidance listed 23 points on creating high-quality sites, https://webmasters.googleblog.com/2011/05/more-guidance-on-building-high-quality.html. It’s all about your website’s quality.

Change the year of the copyright footer. E.g. change to 2006-2016 and not 2006+ or just 2006.
