Report it to Google
- Free
- Days to weeks
- Low to moderate, and entirely dependent on picking the right ground
It only works if the review breaches a specific policy: fake engagement, conflict of interest, off-topic content, harassment, publication of personal data, hate speech or sexual content. Google spells it out:
«Do not report a review just because you disagree with it or do not like it. Google does not get involved in disputes between businesses and customers.»
Here is the difference between working and not working: reporting under the correct policy ground rather than with a generic “it is fake”. If you are turned down, the appeals tool takes up to 5 working days, and businesses in the European Economic Area have additional routes.
Google has no programmatic way of receiving reports. Only its web interface. Anyone selling you “automated takedowns” is deceiving you.
