Bing has introduced JSON-LD support as part of Bing Webmaster Tools.
Users can now validate their JSON-LD implementation by logging into Bing Webmaster Tools and using the Markup Validator tool, which can be found in the Diagnostics and Tools section.
Following the inclusions of JSON-LD, Bing’s Markup Validator now supports six markup languages:
From the official announcement:
Bing emphasizes the benefits of using JSON-LD, explaining how it can be implemented without modifying the HTML content of pages.
JSON-LD can also be hidden in the header, body, or footer of a page.
“This effectively means that webmasters can go about designing their pages as they like without having to worry about arranging the information for markup implementations. JSON-LD makes defining links and relationships between data and entities between the data present on your pages easy because it supports nested data.”
The versatility of JSON-LD is exactly why webmasters should be proactive with respect to ensuring the markup is valid.
Lastly, Bing reminds site owners that putting spam data in JSON-LD markup can affect a page’s presence in search results.
JSON-LD markup may not be visible on a page, but it is still visible to search engines.
