How to Identify Fake Competitor Reviews

Competitors posting fake negative reviews is prohibited by Google and can raise issues under the Australian Consumer Law. But suspicion is not proof. This guide covers the signals that genuinely point to a competitor, how to document them, and how to avoid accusing the wrong person.

Why competitor reviews break the rules

Google's contributed content policy names industry competitors as an example of a conflict of interest, and it separately prohibits posting content on a competitor's business to damage its reputation. Either way, a review written by someone with a commercial interest in making you look bad is not a review of a customer experience.

The signals worth looking for

No single signal proves anything. What matters is when several point in the same direction.

Signals in the reviewer's profile

• A pattern of one-star reviews for businesses in your industry and area, often alongside a five-star review for one particular competitor.
• A new or near-empty account whose first activity is a negative review of you.
• A name, photo or profile link that connects to a competitor's staff, owner or family (for example via public social media or LinkedIn).
• Local Guide activity that does not fit, such as reviews only in your niche across a wide geographic area.

Signals in the review itself

• Industry jargon or technical detail an ordinary customer would not use.
• Recommending a competitor by name: "Go to X down the road instead."
• Generic complaints that do not match any service, staff member or date in your records.
• Phrasing repeated across several reviews posted close together.

Signals in the timing

• A cluster of negative reviews just after you opened, moved closer to a competitor, launched a promotion or won a contract.
• Reviews posted when you were closed or before you began trading.

How to document what you find

1. Screenshot each review and reviewer profile with the date visible, and copy the direct link to each review.
2. Build a simple table: reviewer name, date, rating, which competitor they praised, and any link to that competitor.
3. Check your records for any genuine dealings with the reviewer.
4. Record public connections only. Use public information. Do not attempt to access private accounts or pose as someone else to obtain information.
5. Keep it factual. Write down what you can see, not what you assume.

Reporting competitor reviews to Google

Report each review through your Business Profile or the Reviews Management Tool, choosing the reason closest to conflict of interest or fake content. If a report is rejected, use the one-time appeal to explain the connection in a few factual sentences, for example: "The reviewer's public profile lists them as a manager at a competing business 2 km away. They have left five-star reviews for that business and one-star reviews for three of its competitors in the past month." Step-by-step instructions are in our guide on how to report a fake Google review.

If a competitor is posting fake positive reviews on its own listing, you can report those in Google Maps too.

The Australian Consumer Law angle

Under the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010), a business must not engage in conduct in trade or commerce that is misleading or deceptive (s 18), and must not make false or misleading representations, including representations that purport to be testimonials (s 29). The ACCC has taken action over fake online reviews and publishes guidance for businesses on online reviews. A competitor posting fake reviews to steer customers away from you may raise these issues.

In practice, the ACL is usually more relevant as background than as a removal tool. You can report concerns to the ACCC, and a lawyer can advise whether private action is worthwhile, but neither is a quick way to get a review taken down. Our page on the Australian Consumer Law explains the provisions in more detail. This is general information, not legal advice.

Mistakes to avoid

• Do not accuse a competitor publicly in your reply. If you are wrong, you have created a defamation risk for yourself.
• Do not retaliate with reviews on their listing. It breaches the same policies and undermines your complaint.
• Do not assume every bad review is a competitor. Genuine customers have bad days too, and treating them as saboteurs shows in your replies.

A hypothetical example

For example, imagine a dental clinic that opens in a suburb with one established practice nearby. Within three weeks, it receives four one-star reviews. Two come from accounts with no other activity. The other two come from accounts that have left five-star reviews for the established practice and one-star reviews for two other clinics in the area. None of the four names appear in the new clinic's patient records, and one review mentions a "hygienist" the clinic does not employ. Each signal on its own is weak. Together, documented in a simple table, they give Google a coherent picture to assess. Even so, the outcome is Google's call, and the clinic should still reply neutrally to each review in the meantime.

How G-DEFENCE helps

We assess suspected competitor reviews for Australian businesses, help pull the evidence together, and lodge complaints through Google's official channels. Fees apply only after a successful removal (see pricing), and Google makes the decision. Our fake Google review removal service page explains our approach.

If you think a competitor is behind reviews on your profile, request a free assessment and we will give you a frank view on the strength of the evidence.
