Report it from your Business Profile, pick the closest reason the menu offers, and save the conflict-of-interest argument for the appeal. The appeal is where you name the policy yourself.
Open Read reviews on your profile, select Report next to the review, choose a reason, and send it. Google says evaluation typically takes several days. The Reviews Management Tool shows Decision pending until Google looks, then Report reviewed - no policy violation if Google leaves the review up.
Don't count on a Conflict of interest reason being on the menu. Google's help page gives two example reasons, spam and profanity, and doesn't publish the rest. On the Local Search Forum in June 2025, Stefan Somborac had a screenshot from December 14, 2024 that showed the option. When he checked that June he didn't see it, and members in the thread found the menu varied from one Google account to another. We don't know what your menu shows today. Somborac's point in the same thread is the one to keep. The flag list doesn't cover every policy, and the appeal is where you name the one the review breaks.
So pick the reason closest to what the review does. For a review about working somewhere rather than buying something, in our read that's the off-topic reason, if your menu has one. The flag asks Google to look. The appeal carries the argument.
If the report comes back with no violation found, you may be eligible for one appeal, and only one. For a former employee, the appeal names Rating Manipulation and quotes the clause. Then it lays out the employment in plain sentences. The role and the dates. How the name on the review matches your records. The fact that no sale exists under that name. Name a policy that doesn't match that argument and you can waste the one appeal by presenting the wrong policy argument. Read how the one-time appeal works before you spend it. You file it from your own profile. We never submit anything to Google.
