Hi there,
Your business must be a verified business with “Google My Business” and it must have a physical address where you serve customers.
You can read about that here:
https://wordimpress.com/documentation/google-places-reviews/google-places-reviews-101/
In that article you’ll see the section called “Testing Whether Your Business Profile is Configured Correctly” Use the link there to test whether your business shows up correctly on the Google website linked to. If it does, please provide me a link to your business on Google Maps where I can see your reviews and then I can test.
Thanks!
