If you are missing reviews from your Google My Business Profile, one of these reasons may apply:
Review shows on Search but not Maps, or vice versa
Sometimes, a review takes longer to show on Google Search than on Google Maps, or the other way around. This is exceedingly common after merging Google My Business profiles. If your reviews still don't show after a week, you can contact Google Support.
Reviews after business profile reinstatement
If your reviews went missing after Google reinstated a disabled or suspended profile, contact Google Support to have them investigate for you. You can reach Google Support here.
Other missing reviews
To protect customers, Google removes reviews with inappropriate content, advertising, spam, off-topic reviews, or conflicts of interest. You can learn more about Google's review policies here.
Sometimes, Google's algorithms remove legitimate reviews. After a review is removed, Google says they can’t restore it and further states, "These removal measures help keep reviews relevant, helpful, and trustworthy."
