Google recently announced that the Rich Results Test Tool has now transitioned out of beta and fully supports all Google Search rich results features. What, pray tell, is a rich result feature you ask? A rich result is when the result you see on a Google search engine results page (SERP) is more than just the standard blue link - things like carousels, images, videos, top stories listings.
The rich results features work on structured data - code that helps a searchbot more accurately understand the meaning of content. For example, structured data code can help Google understand the difference between things like a chocolate cake recipe and a chocolate cake to buy, making the search results more accurate for the end-user.
Errors in a site's structured data code disqualify the page from being shown as a rich result in Google Search, so it is a good idea to check your site using the tool - Rich Results Test Tool.
If you need developer support to add or edit structured data on your website, feel free to get in touch.
