Matt Cutts posted about giving feedback to Google, when you come across a page with “no results found” or “empty review” pages, whenever you perform search, which falls under Google’s webmaster guidelines in a few ways. Here’s how to report a bad user experience.

Overall Rating: No Ratings. Leave Your Ratings or Reviews here!” The page doesn’t actually have any information or reviews of the blue widget product.
