Does Google Verify That Reviews Are From Real Customers?

The short answer: no purchase verification

Google doesn't ask for a receipt, a booking reference, or any proof of a transaction before publishing a review. Anyone with a Google account can leave a star rating and a written review for any business listed on Google Maps or Search, whether or not they were ever actually a customer.

That surprises a lot of business owners, especially after receiving a review that clearly doesn't match anyone in their booking system or till records. It's not a bug or an oversight — Google has built its review system this way from the start, and it applies to every business on the platform, not just yours.

What Google does check

Verification happens after publication rather than before it. Google runs automated systems that look for patterns associated with spam and fake engagement — the same account posting many reviews in a short window, reviews that don't mention anything specific to the business, or activity that matches known manipulation networks. Content also has to follow Google's review policies: no hate speech, no conflicts of interest, and no content unrelated to an actual experience with the business.

None of that is the same as confirming a transaction took place. A review can pass every one of Google's checks and still be from someone who never set foot in your business — it just has to look like a genuine account posting a genuine opinion, whether or not the underlying claim is true.

Why this matters for how you respond

Because there's no purchase verification, "I don't recognise this customer" isn't, on its own, grounds to have a review removed. Google's removal process is built around policy breaches — spam, hate speech, conflicts of interest, or content about a completely different business — not around a business owner's inability to match a name to a transaction. A review can be unwelcome, unfair, and still fall within what Google allows to stay up.

That's frustrating in the moment, but it also cuts the other way: it means a competitor can't get your reviews removed just by claiming they seem unverified, and the same rules apply evenly across every business on the platform.

What you can actually do

If a review breaches Google's policies — it's clearly spam, from someone who says outright they were never a customer, or contains content that has nothing to do with your business — you can flag it for removal through your Google Business Profile.

What you can't do, on either side of this, is fabricate reviews. Posting fake positive reviews about your own business, or asking staff, friends or family to post them without disclosing the connection, is treated by the ACCC as misleading conduct under the Australian Consumer Law — the same standard that makes a fake negative review about a competitor a problem too. The absence of purchase verification isn't licence to game the system in either direction; it's a reason to focus on the reviews you can influence honestly.

Building a profile that holds up regardless

Since no review arrives pre-verified as trustworthy, the practical answer is to make your profile resilient on its own terms: a steady flow of reviews from real, recent customers, asked for directly and never incentivised or gated, plus considered replies to the ones that land badly. A profile with genuine volume and a visible pattern of thoughtful responses reads as credible to a future customer even when one review in the mix looks questionable.
