What evidence supports a Google review complaint?

A review complaint succeeds or fails on what Google can verify. The right evidence shows which policy or law the review breaches; the wrong evidence — or customer data used carelessly — can weaken your case or create a privacy problem of your own.

Start with the review itself

Reviews change. Reviewers edit them, add photos, delete them and repost them. Capture a record as soon as you see a problem review:

• A full-page screenshot showing the review text, star rating, reviewer display name, the date shown, and your business name, so the image is clearly tied to your profile.
• The date you captured it. Google displays relative dates such as “2 weeks ago”, so note the actual date and time of your screenshot in the file name or a log.
• The review’s share link, which identifies the specific review for Google and for any legal request.
• The reviewer’s public profile, including other reviews they have posted, if it is relevant to a fake or conflict-of-interest argument.
• Every version. If the review is edited, capture the new version too rather than replacing the old screenshot.

Evidence matched to the ground you are relying on

Gather evidence for the specific breach, not everything you have. Different grounds call for different material:

Not a real customer (fake engagement)

• A search of your booking, invoicing or point-of-sale records for the name and the date described, with a note that nothing matches
• Facts that make the review impossible — the business was closed that day, does not offer the service described, or is in a different suburb
• Patterns across reviews: similar wording, multiple new accounts, posting within a short window

Conflict of interest

• Employment records showing the reviewer was a staff member, and the dates (see ex-employee reviews)
• Publicly available information linking the reviewer to a competing business
• Correspondence showing a personal dispute unrelated to any customer experience

Harassment, threats or extortion

• Emails, texts or messages linked to the review, with timestamps and sender details
• Any demand for money or services, which should be reported through Google’s review extortion process

False statements (potential defamation)

• Documents that show the factual claim is false — a licence, test result, inspection report or transaction record
• Evidence of harm, such as cancelled bookings that refer to the review, which may matter for the serious harm element in jurisdictions where it applies

A note on CCTV

CCTV footage can be compelling — for example, showing that no one matching the reviewer’s description entered the premises at the time claimed. But use it with care:

• Surveillance and listening devices are regulated by state and territory laws, which differ. Footage recorded unlawfully, or audio recorded without the required consent, can cause more problems than it solves.
• Footage of identifiable people is likely to be personal information. If your business is covered by the Privacy Act, its use and disclosure are governed by the Australian Privacy Principles.
• In most cases it is better to describe what the footage shows in your complaint and keep the footage securely, rather than uploading it anywhere or posting stills publicly.

Your privacy obligations when using customer records

The Privacy Act 1988 (Cth) covers most businesses with annual turnover above $3 million, and some smaller ones regardless of turnover — including private health service providers such as dental clinics and medical practices. If your business is covered, Australian Privacy Principle 6 limits how you can use or disclose customer information for a purpose other than the one it was collected for.

The OAIC’s APP 6 guidelines recognise several exceptions that may be relevant to a review dispute, including uses the individual would reasonably expect for a related purpose, uses reasonably necessary to establish, exercise or defend a legal or equitable claim, and uses required or authorised by law or a court order. Even where an exception applies, the OAIC stresses using only the minimum personal information necessary, and the business carries the burden of showing the exception applies. Health information is subject to stricter tests.

Practical rules that follow from this:

• Never post customer details, appointment information or records in a public reply to a review — even to prove the reviewer is lying.
• In a complaint to Google, state conclusions from your records (“no booking under this name or on this date”) rather than attaching other customers’ data.
• Redact third-party personal information from any document you share.
• Keep evidence files secure and limit who in the business can access them, consistent with APP 11.

Organise it before you submit

Keep one folder per review, with a short timeline at the top: when the review appeared, when you captured it, what you reported, and every decision or reference number Google gave you. If the review is later edited, appealed or reposted, that timeline is what makes the next step quick and consistent.

What does not help

• Statements about how much the review has cost you, without linking it to a policy or legal ground
• Positive reviews from other customers, which do not show the negative one is invalid
• Speculation about who the reviewer “must be” without supporting facts
• Long histories of the dispute with a genuine customer

Well-organised evidence is the foundation of every complaint G-DEFENCE prepares. If you have a review and a folder of material, our free assessment will tell you which parts are useful, which ground they support, and whether there is a realistic case at all.
