Once you've uploaded your reviews feed, it's important to verify the status of your reviews in Google Merchant Center > Marketing > Product reviews. This section will highlight any warnings or errors that could be hindering the display of your reviews, along with the specific reviews that are affected.

This article's primary objective is to guide you through resolving these errors and warnings, ensuring that more of your reviews are showcased effectively on Google Shopping.

Following a successful feed upload, your reviews will fall into the following categories:

Each review should only appear within one feed and should not be duplicated across feeds from different stores. Duplications may lead to Google blacklisting specific reviews or even entire feeds. To prevent this:
