I recently noticed that our canonical url's were not set up correctly. The incorrect setup predates me but it could have been in place for close to a year, maybe a bit more. Each of the url's had a "sortby" parameter on all of them. I had our platform provider make the fix and now everything is as it should be.
I do see issues caused by this in Google Webmaster, for instance in the HTML suggestions it's telling me that pages have duplicate title tags when in fact this is the same page but with a variety of url parameters at the end of the url. To me this just highlights that there is a problem and we are being negatively impacted by the previous implementation.
My question is has anyone been in this situation? Is there any way to flush this out or push Google to relook at this? Or is this a sit and be patient situation.
I'm also slightly curious if Google will at some point look and see that the canonical urls were changed and then throw up a red flag even though they are finally the way they should be.
Any feedback is appreciated.
Thanks,
Dave
