Product reviews are a valuable resource for users researching which product to buy. Product reviews often contain a list of pros and cons, which our research has shown to be popular with shoppers when making their purchasing decisions. Because of their importance to users, Google Search may highlight pros and cons in the product review snippet in Search results.
You can tell Google about your pros and cons by supplying pros and cons structured data on editorial review pages. When you're adding structured data to your web pages, you can use Rich Results Test to make sure it's correct and valid for Google Search. The tool has been recently extended to check for pros and cons structured data in addition to all the other structured data types supported by Google Search.
If you do not provide structured data, Google may try to automatically identify pros and cons listed on the web page. However, Google will prioritize supplied structured data provided by you over automatically extracted data. This has been tested by website owners with positive feedback.
To illustrate, here is an example web page with JSON-LD encoded structured data that could be used for the search results experience described above. Note that the text in the structured data must match the text on your page exactly.
The text provides a detailed summary of the pros and cons of the product. The positive aspects of the product include its consistent results and sharpness. However, the negatives include the lack of child protection and advanced features.
Currently, only editorial product review pages are eligible for the pros and cons enhancement in Search, not merchant product pages or customer product reviews. The experience is available in Dutch, English, French, German, Italian, Japanese, Polish, Portuguese, Spanish, and Turkish in all countries where Google Search is available.
