Anonymous URL Submission Tool Being Retired
Saying Goodbye is never easy, but the time has come to announce the withdrawal of anonymous non-signed in support Bing's URL submission tool. Webmaster will still be able to log in and access Submit URL tool in Bing Webmaster Tools, and this is easier than ever as the tool now supports Google and Facebook authentication in addition to existing Microsoft accounts.
Why say goodbye?
Well, the URLs received are by far too low quality to be trustable, and webmasters preferring having more ownership of the URLs for their site.
In order to use the tool, webmasters just need to login, add and verify their site. Then navigate to the Submit URL tool within the Configure My Site menu options.
In case the webmasters want to use our Bing Webmaster tools API, webmasters have to generate an API key through Bing Webmaster Tools and follow the guidelines for its usage here. In case you haven't signed up on the tool yet, please click here to sign up.
Thank you,
The Bing Webmaster Tools Team
