Have you tried using the structured data properties apart from the ones listed in the Google Developers site? Are you confused about whether these will help you rank in rich snippets? Well, you’re not alone!

In the latest installment of #AskGoogleWebmasters video series, John Mueller from Google responded to a query that asked: “[Do] we need to use structured data as per the Google Developers site (including required/recommended properties) or can we use more properties from Schema.org apart from the Developers site?” You can check the official tweet below.

John Mueller’s Response to Structured Data Properties

In response, Mueller said that it is completely okay to use structured data properties apart from the ones listed in the Google Developers site. Structured data present on the Google Developers site is what Google originally supports as rich results.

This is what his original response was, “Google uses structured data in the search for both supporting rich results types as well as for better understanding the pages themselves. With that in mind, in order to be eligible to be shown as a rich result, you need to make sure that the page uses the right structured data and that it complies with the appropriate policies on our side. However, even without the structured data leading to rich results, our system’s profit by understanding the page is better when they use structured data.”

Google uses structured data to understand the content present on a webpage. Structured data is coded using an in-page-markup on the intended page. All structured data must be tested using the Structured Data Testing Tool during the development stage, followed by the Rich Results Status Report post-deployment. Google Search supports structured data in three different formats, JSON-LD, Microdata, and RDFa. 

Criteria For Structured Data Content

The content intended to showcase as structured data must fulfill the following criteria:

  • Information of the structured data must be up-to-date
  • Content must be original
  • Don’t markup content that is invisible to the readers
  • Don’t markup irrelevant content
  • Don’t markup content that promotes illegal and offensive goods or activities

John Mueller from Google said that using structured data apart from the ones supported by Google is optional for users. Even though Google may not support structured data in the form of rich snippets, it may still use them to understand the content of the page. This will also help these pages to rank well accordingly, if not get a place in the featured snippets. 

“Keep in mind that it’s not guaranteed for us to show these rich results just because a page uses the appropriate structured data, so in short, if you’re aiming to be eligible for specific rich results type in Google search, then you should definitely watch out for the requirements independently. You’re always welcome to use structured data to provide better machine-readable context for your pages, which may not always result in visible changes but can still help our systems to show your pages for relevant queries,” said John.
