I operate a website where we added a lot of items a couple months ago. Since then it seems we have dropped quite a bit in the google rankings. We had only about 10 items in the store about a year ago. And then we were doing well with those. But for some reason when we added several hundred items to the store, our hits have dropped quite a bit. Even the pages that aren't part of the store used to get a lot of hits and we would get calls regularly on those items. But recently there's been nothing. Any ideas as to what happened?
