Google panda has been update on 3 nov. 2011 as i read an article on a seo website. In this update google has affected the websites which are based on Tech (some posts), Price, News, Top10, Top 5, Events, Gadgets, sports, movies, etc… because this website data frequently update. If there is no updation with quality content, the website will get lower rankings.. i have also a gemstone beads website and it has got price but our prices does not vary... Please let me know if someone has update about Products based websites.
