Query parameters for normalization in Bing

[EcommerceSite]

Almost everyday I get this-

Query parameters for normalization found on www.sitename.com

Site: www.sitename.comDate: 3/26/2013Priority: LowBing has detected new parameters in your URLsAnyone know why? We aren't changing anything. I have read it has to do with internal urls but I can find out what internal urls this is a problem with.

We see this too.  We have canonicals in place, and we still see the error.  And there's no insight into which parameters are causing issues.

Here's an answer straight from Duane Forrester of Bing:

"It means that those parameters may be causing Bing to think you have duplicate content issues.  If your content can appear on two individual URLs, that can be an issue, as we don't know which one you want indexed, ranked, etc.  So, the tools we offer allow you to control this by telling us to ignore a parameter.  We can suggest parameters we find, but it's your choice on if you want to tell us to ignore them (and the attendant URLs) or not.

For example, if you have a /print/ folder on your site, you can tell us to ignore everything under the "print parameter".  By entering "print" as the parameter to be ignored, we'll skip indexing the content held in the print folder on your site."

Duane doesn't say so in the article, but you can adjust your parameter settngs in Bing Webmaster Tools. Info here:
