Bing has detected new parameters in your URLs. Please visit the Ignore URL Parameters feature in the Configure My Site section of Bing Webmaster Tools 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. what it is mean?
