no rankings for urls with query strings

Url

http://mydomain.com?productid=2 for keyword1

could have a different SERP than

http://mydomain.com?productid=2 for keyword2

But this information does not seem to be reflected in the digitalpoint tool. So I have to keep checking in google.

I am not sure if the google api allows this, but if it does, it would be great if the tool reflected this capability.

For now, I am rewriting a bunch of urls to be just file name without url string-- this seems to result in better ranking in google anyway. Still would be nice if this feature could be added.

(PS Overall though, great tool, I use it a lot!)

Best Regards,

Thomas.
