Recently, I noticed that a new tool has been added tool to the crawl section of Bing webmaster tool named Markup Validator.
This tool is very useful to check if the added code is actually going to be readable, as intended. Though, adding inaccurate code will not cause your page to render any differently in most cases. But if the syntax is incorrect Bing will not recognize data on the page as you intended.
So, if you have added any markup code on your blog or website you should check URLs for valid markup code from inside your webmaster tools account because Bing might use the structured markup to display rich snippets for your URLs.
To access this new tool you need to login to Bing Webmaster tool and click on the ‘Crawl’ tab. Under this tab you will find ‘Markup Validator’ on the far right side, click it and start verifying URLs for vaild markups.
This tool scans for the following markups :
Here’s the screenshot of what the results would look like:
