Google Review QR Code: how to create one, where to put it, and the mistake that gets you penalised

A review QR code solves the most annoying part of asking for a review: the customer is willing, but has no idea where to tap. They point the camera, and they are already on the right screen.
Generating the code is the easy half, and it is free. The hard half is what happens afterwards, and almost nobody writes about that.
What a review QR code actually does
A review QR code is an image that stores a web address. When someone points a phone camera at it, the phone opens that address without anyone typing a thing. For reviews, the address is your business on Google with the review box already open. The customer taps the stars, writes something if they feel like it, and posts. The gain is not technological, it is about friction: asking someone to search your business on Google, scroll to the right button and write there is asking for three decisions. Pointing a camera asks for one. That is why the same request, made with and without a code, tends to produce different numbers of reviews. The code does not convince anyone to leave a review; it simply stops getting in the way of people who already wanted to.
How to create yours, in three steps
1. Find your business review link. Search your business name on Google, open the panel on the right (or the card in Google Maps) and look for the button to write a review. The address that opens is what goes inside the code. If you manage the profile, Google also gives you a ready made short link inside your Business Profile.
2. Turn that address into a code. Any QR generator does this, and the free ones work. Just check two things: that the code does not expire, and that it does not run through a link shortener that could disappear. A code glued to a table is the one piece of your marketing that becomes physical, and reprinting signage is expensive.
3. Test it with a phone that is not yours. This is the step everybody skips. Ask someone to point their camera and see where it lands. A code that goes to the wrong page only gets discovered when a customer complains, and by then you have printed a hundred.
The size that actually works in print
The rule of thumb is reading distance. A code needs to be roughly one tenth of the distance it will be read from.
| Where | Size that works |
|---|---|
| Table card, read from 30 cm | 3 cm is enough |
| Counter sticker, read from 50 cm | 5 cm |
| Wall sign, read from 1.5 m | 15 cm |
| Window poster, read from the pavement | 30 cm or more |
And the detail that ruins the most print jobs: export large and scale down, never the other way round. A code saved at 200 pixels looks sharp on screen and blurry on paper. For print, ask for at least 1,000 pixels per side.
Leave a white margin around it, about the width of one of the code's own little squares. Without that margin the camera loses the edge and takes longer to read.
Where to put it, and why placement beats design
The best spot is where the person is already standing still and happy. In order of how well they work:
- On the bill, or next to it. The customer has just been served well and already has the phone out to pay.
- On the table, standing up. It is visible all through dinner, and nobody has to ask.
- On the counter, by the exit. It catches the people who bought and are leaving.
- On the packaging or the receipt. It catches the takeaway customer, who is the one most likely to forget.
What does not work: the front door, where nobody has anything to review yet, and the bottom of the menu, where the code competes with the food.
Write a line next to it. A bare code does not say what it is. "Point your camera and tell us how it went" outperforms a code with no caption, and it costs one line.
The mistake most tutorials teach, and Google forbids
Search for "review QR code" and you will find plenty of articles recommending the same trick: the code first goes to a page of yours asking whether the experience was good; if the person says yes, they continue to Google; if they say no, they land in an internal form and never reach Google.
That is called review gating, and Google's policy prohibits it. Filtering who gets to review publicly based on their rating puts your profile at risk, and the profile is the asset you are trying to build in the first place.
The confusion happens because there is a legitimate version of the same idea, and exactly one thing separates them: the path to Google has to stay open to everyone, whatever the rating. You may ask how it went. You may offer a direct channel to fix a problem before it becomes public text. What you may not do is hide the door to Google from someone who had a bad experience.
In practice: offer both on the same screen, every time, and let the customer choose.
What happens after the scan, which is the hard part
Generating the code takes two minutes. What happens over the following week is what decides whether it was worth it:
- A review arrives and nobody sees it. Google does not call you. The notification dies in an inbox you do not open.
- You see it and do not reply right away. Replying joins the "later" list, and later becomes next week.
- A public complaint arrives that could have been solved at the counter, if anyone had known about it while the customer was still there.
A QR code that raises your review volume while nobody is minding what comes in also raises the volume of what you did not answer. Someone reading your profile does not just see the complaint: they see an owner who did not reply.
How Binno does it
Binno generates the codes and looks after what comes back, which are two halves of the same job.
On the code side: you create as many as you want, each with a name (table 1, counter, delivery), pick the size in centimetres and download it ready for the printer. The code is generated inside Binno, with no dependency on a third party service that could go offline and take your sign with it.
On the customer side: the screen that opens always offers the public Google path, whatever the rating, because the alternative is against the rules. Someone who had a problem also gets a direct line to you, which is what lets you fix it while they are still there.
On the owner side: when the review lands on Google, Binno messages you on WhatsApp straight away, with a reply already written in your business's voice and in the language the customer used. You read it, change whatever you want, and approve with one tap. Nothing is published without that approval.
