Can Google detect fake reviews? Rules and UK law

"Can Google detect fake reviews?" sits right under "How do I get more Google reviews?" in the People also ask box. For a small business, the real questions are: what does Google treat as fake, what happens if it finds it, and what does UK law now say? Everything below is from Google's policy pages and the Competition and Markets Authority (CMA), checked 15 October 2026.

What Google treats as fake

Google's Maps content policy says contributions must reflect a genuine experience, and lists as fake engagement (Google):

• reviews not based on a real experience
• reviews or ratings paid for, directly or in kind
• content posted from multiple accounts by, or at the request of, one person
• content posted with emulators or other tools that mimic genuine activity

It also counts as rating manipulation "content exhibiting unusual volumes or patterns of review contributions", reviews from people with a conflict of interest (staff, family, competitors), and reviews posted because of an incentive. Google doesn't publish how its detection works, but those are the patterns it says it acts on.

What businesses can't do

Google doesn't allow businesses to:

• offer payment, discounts or free goods or services for a review, or for changing or removing a negative one
• discourage negative reviews, or ask only happy customers ("review gating")
• pressure customers to review on the premises, or ask for specific wording
• set staff targets for a number of reviews

What is allowed: asking customers to share a genuine experience, with no incentive and no attempt to steer the rating (Google).

What happens if Google finds fake reviews

Google removes the reviews. If it decides the business owner broke the fake engagement policy, it can also restrict the profile, for example by stopping new reviews for a set time, unpublishing existing reviews for a set time, or showing customers a warning that fake reviews were removed. Google emails the owner first, and you can appeal (Google).

UK law since April 2025

Separately from Google, the Digital Markets, Competition and Consumers Act 2024 made fake reviews a banned practice from 6 April 2025. It's illegal to write or commission fake reviews, to hide that a review was incentivised, or to publish reviews in a misleading way. Businesses that publish reviews (on their own website, for example) must take reasonable steps to prevent and remove fake ones, and should have a published policy (CMA).

The CMA can now fine a business up to 10% of its global turnover for breaking consumer protection law (CMA). Review swaps with other local firms, or a free extra service in return for five stars, are exactly the kind of thing the rules target.

If someone posts fake reviews about you

• Flag it. Google lets you report a review you think breaks its policies (Google). Point to the specific rule: no record of the customer, a competitor, or a sudden burst of one-star reviews.
• Reply calmly. Say you can't find a record of the job and invite them to get in touch. Don't accuse or share private details.
• Keep records. Job dates and customer names make it easier to show a review isn't genuine.

Getting genuine reviews instead
