You can report a review you believe breaks a platform's rules, but a negative opinion alone is not a reason for removal. Google says it removes reviews that violate its policies and does not resolve disputes between businesses and customers.
On Google, open your Business Profile, choose Read reviews, select Report next to the review, choose a reason and send. Google says checks typically take several days. If Google finds no violation, you can make one appeal through its Reviews Management Tool.
On Tripadvisor, owners can use Report problem with review. Tripadvisor says the company will research the complaint within 48 hours. A report starts a review process; removal is not automatic.
Keep a clear record of your concern and choose the relevant policy reason. While waiting, consider whether a calm public response would help future guests understand the issue. Do not accuse the reviewer of fraud or share private information in a Tripadvisor response.
Do not offer a discount or other incentive to remove or change a review. Google and Tripadvisor both prohibit relevant forms of that practice.
