The value of schema markup is often measured in an increase in click through rate when you get a rich result in search. The rich result often shows the price, images, and rating for products or other website content as described in Google's documentation found at: https://developers.google.com/search/docs/guides/). Most recently, Google released additional case studies on the value of schema markup, showing the value beyond an increase in click through rate. Here are the results from their three case studies:

• Rakuten saw 2.7X more traffic from search engines and 1.5X increase in session duration.

• Eventbrite saw a 100% increase in the typical year over year growth of traffic from Google Search to event listing pages, according to Google Analytics.

• ZipRecruiter saw 3X higher conversion rate from Google than from other search engines, 4.5x higher Google organic conversion rate than it was previously, 10% lower bounce rate for Google visitors to job pages, and 35% more monthly organic non-branded traffic.
