Bing Webmaster - Ignore URL Parameters strange behaviour

[MrOnTheRopes]

Hi,

I got tired of BW complaining about these parameters

'Bing has detected new parameters in your URLs. Please visit Ignore URL Parameters to review the suggested parameters. If you are certain that a suggested parameter does not change or determine the page content, you can add it to the list of parameters to ignore by clicking on the suggested parameter. This helps reduce duplicate URLs for the same content and allows Bing to crawl and index more relevant URLs, potentially improving the overall traffic for your site.'

So I added all the suggestions to the Ignore URL Parameters list.

All was fine for about a week and then I get another message. When I went back the IUP only a couple remain from the original 10 or so, so I have to add them again. This has happened quite a few weeks running.

Does anyone know why this is happening?

Many thanks :)

Is it possible that by selecting all of their suggestions that you selected any URL parameters that did not apply to your URLs? If they continue to deselect the same parameters, are you certain that those parameters exist on your site?
