According to an announcement, Google has added new filters to the performance report within Google Search Console in order to show you how well your product results are doing in search. Click and impression data will now be displayed when rich results display based on your use of product rich results markup.
The data can be found under the Performance report by clicking on “search appearance” and then on “product results.” Clicks an impressions can be further segmented by device, geography and queries.
Below is a screenshot of what a product rich result looks like, but you can learn more about this in this developer document. Typically, product rich results show product ratings, price, availability and some description information.
