Hi, Google traffic for my website has dropped by 70-80% all of a sudden, since 22nd Oct 2010. No major changes have been done to the site. I used to rank well for most of our products. We have added a few new products and modifies just a few and re-submitted the sitemap, after which we saw this major drop-down in ranking. Can anyone help or suggest what needs to be done. Regards, Shahed
