Can a café use a QR code that only lets 5-star reviews through to Google?

Cupán Studio sells café websites. We build them for cafés in Ireland and write about Google listings, so we have an interest in café owners reading this. We do not sell review tools.

No. Google's Maps policy says merchants must not "discourage or prohibit negative reviews, or selectively solicit positive reviews from customers". A QR code that sends only 5-star ratings to Google does exactly that. A QR code that asks every customer for a genuine review, whatever they think, is allowed, and Google's own help page suggests it. Staff should not pressure people on the premises to post, and a discount or freebie in return for a review is not allowed either.

Where the question came from

A poster asked it in r/LocalGuides on 6 May 2025. They said a café in their city uses a QR code that "only allows customers to post 5-star reviews on Google", and asked how to report it. The thread does not say which city, and we do not name or guess the café. It had 10 comments.

Can a café filter out bad reviews with a QR code?

No. Google's Maps User Generated Content Policy lists, under Rating Manipulation, what it does "not allow merchants" to do. One item is to "Discourage or prohibit negative reviews, or selectively solicit positive reviews from customers". The poster described a code where, if someone picks fewer than 5 stars, "the review doesn't go through or redirects elsewhere". That is a filter on who gets to post, which is what the policy calls selectively soliciting positive reviews.

I can only report what the policy says. I cannot say what Google would do about one particular business. The poster also confirmed that a customer can still leave a lower review by finding the café on Google Maps directly: "Yes, one can do that."

Can a café ask for reviews with a QR code at all?

Yes. Google Business Profile Help says: "To leave reviews, you can ask customers to visit a Google link or scan a QR code." The Maps policy says merchants are allowed to "Solicit or encourage the posting of content that does represent a genuine experience, without offering incentives to do so or attempting to influence the rating or the contents of the review." As the poster describes it, the problem is not the QR code but what sits behind it.

Can staff ask customers for a review at the till?

Asking is fine. Pressure is not. The policy says: "When soliciting reviews, merchants should not require or pressure users to leave ratings or write reviews while on the premises, nor should they request that specific content be included." It also lists merchants "requesting that staff solicit a certain number of reviews", and requesting that staff solicit reviews with specific content. The poster said the people in that café are "very pushy" about the code when they bring the bill. We only have the poster's word for that.

Google also does not allow incentives. The policy bars offering "payment, discounts, free goods and/or services" in exchange for posting a review, or for changing or removing a negative one.

What should a café do instead?

This part is our view, not Google's. Make one QR code that opens the normal Google review page, show it to every customer in the same way, and offer nothing for a review. Let people say what they thought. Then reply to what comes in: our article on replying to Google reviews covers how. Google's help page says: "Honest and balanced reviews can help potential customers decide. A mix of positive and negative feedback often feels more trustworthy." A run of only 5-star reviews is not the aim.

How do you report a café doing this?

The thread gave one route. A commenter said "This is unusual" and suggested reporting it to the Google Business Profile team through the Business Profile help page the commenter linked. That is the commenter's suggestion, not a process we have checked with Google, and we do not know what the outcome would be. Another commenter in the thread was doubtful that Google could do much. Meanwhile the poster's own point stands: a customer can leave their honest rating on Google Maps whatever the QR code does.
