Proof of the danger of the review field in your Shopify store and getting reclassified as a Critic Review Rich Result
Published: October 24, 2019
Many customers have emailed about the warning on the review field in their product data since Google made it an optional field back in December 2018.
Iāve written about how itās used for Critic Reviews but even with mine and Googleās documentation around it (which was deprecated in June 2021 so I canāt link you to it), some people still insist on using it.
Well, I finally have proof of why you donāt want to populate that review field.
A customer emailed me asking about why they lost their Product Rich Reviews.
Hereās what they had showing up (data anonymized)

Looking at the data behind it, they had the regular Product data type but with the review field populated with their customer review content from some other source.
By filling out the review field, they lost their regular Product Rich Result and was given a Critic Rich Result instead.
Notice the āReview by Kristenā part?
Thatās not the business or even the author of the page.
Kristen is the name of the first customer to leave a product review.
With this incorrect review data, Google thinks Kristen is now the author of that page. And itās no longer a product page in Googleās eyes, itās a page where Kristen has written a review on the product, like an editorial.
Think about that name for a secondā¦
They are lucky the first reviewer wasnāt by āThis company sucksā, āGarbage productā, or someone who has seen any of Bart Simpsonās prank callsā¦
Just think if your worst customers were able to take over and write the content for your search results.
The bigger problem is that anyone at Google who performs a manual review will see that this is a product page and not a critic review or what Google now calls an editorial review.
This means this store could be hit by manual action and risk losing all of their Rich Results.
Remember, manual actions are very bad and can have far-reaching impacts based on how appropriate the Googler thinks the punishment should be. Iāve seen entire domains removed from Google for messing with reviews.
If a site has a manual action, some or all of that site will not be shown in Google search results.
Straight from Googleās guidelines :

Which links to their Manual Actions Report with this in bold:
If a site has a manual action, some or all of that site will not be shown in Google search results.
Google doesnāt get much clearer than this.
The good news is that I was able to find the problem code for the customer and tell them what they needed to do to fix it. Less than a month later, their Product Rich Result is back: (again, data anonymized)

So you might be asking yourself what caused all this and how can you prevent it from happening to your store.
The root cause was their review app adding data to review field. The customer didnāt even know it was happening, they just noticed their review stars disappeared.
That app added code to link their data to JSON-LD for SEOās data, thereby getting JSON-LD for SEOās data reclassified.
This wasnāt some small review app either, they have dozens of employees, and many claims to be experts on this stuff. Iāve gotten into many an argument with them over even the basics of how structured data works and pointed them to my own research about structured data.
Luckily, this merchant was only temporally hurt and was able to recover their Rich Results. But many review companies continue to put data into the wrong places and then wonder why their customers are losing Rich Results. This one is just one of a handful who do this with the review field.
Iāll end this story on a clear note:
If you use a review app that puts data into the Products review field, get a new review app.
Itās not worth trying to argue with them that they are wrong. There are plenty of review apps run by people who actually understand how structured data works or are humble enough to ask someone or test their assumptions.
Googleās coming down extremely hard on stores abusing Rich Results. They donāt care if it wasnāt your fault. If your site has the wrong review data then itās your responsibility to fix it, or lose out and take whatever consequences Google judges you by.
This is just one small portion of the kind of service I give to my JSON-LD for SEO customers. Thereās a reason why itās the safest choice for structured data in the app store and has been since 2015.
