Google Webmaster Central is suggesting I add some parameters to exclude from indexing. It has a huge list of parameters similar to this:
discussion4c0a55309fe44
There’s probably several hundred of these, and the “discussion” part is always the same, but the numbers/letters combinations afterwards are all different, making it appear to Google Webmasters that there are several hundred different parameters. Does anyone know what is causing these and what to do about them?
