In our previous post in the structured data series, we discussed what structured data is and why you should add it to your site. We are committed to structured data and continue to enhance related Search features and improve our tools - that’s why we have been creating solutions to help webmasters and developers implement and diagnose structured data.
This post focuses on what you can do with Search Console to monitor and make the most out of structured data for your site. In addition, we have some new features that will help you even more. Below are the new additions, read on to learn more about them.
  1. Unparsable structured data is a new report that aggregates structured data syntax errors.
  2. New enhancement reports for Sitelinks searchbox and Logo.

Monitoring overall structured data performance

Every time Search Console detects a new issue related to structured data on a website, we send an email to account owners - but if an existing issue gets worse, it won’t trigger an email, so it is still important for you to check your account sporadically.
This is not something you need to do every day, but we recommend you check it once in a while to make sure everything is working as intended. If your website development has defined cycles, it might be a good practice to log in to Search Console after changes are made to the website to monitor your performance.
If you’d like to have an overall idea of all the errors for a specific structured data feature in your site, you can navigate to the Enhancements menu in the left sidebar and click  a feature. You'll find a summary of all errors and warnings, as well as the valid items.
