From the counter card to the review box in one scan.
Most customers who would happily leave you a review never do, because finding the listing on a phone takes four taps and a guess at the right branch. A printed code removes the search. It drops the person straight on the star rating for your listing, while the job you just did is still fresh.
This is a link code. The pattern carries one web address, the one that opens Google's review box for a single listing, and nothing else. A phone camera reads it, the browser opens the address, and the person arrives at the stars and the comment field for your business. Someone already signed in to a Google account sees the box immediately. Someone signed out is asked to sign in before the review can post, which is Google's rule, not something a code can route around.
Nothing about the review passes through this site. What you print is a shortcut to a page on Google, which is why it keeps working with no account here, no expiry date and no scan limit.
Leave the quiet zone alone: four modules of clear space on every side, or the reader has nothing to lock onto. Work out the size from the reading distance divided by ten, so a sticker read at 30 cm can be small, while a window decal read from two metres across the pavement needs roughly 20 cm. Under 2 cm nothing is dependable at arm's length. Dark on light, always, since inverted codes are still refused by older scanners. A logo in the middle is fine if error correction stays on Q or H.
What the code cannot do is worth saying out loud. It will not make a pleased customer write anything, it cannot remove a bad review, and this type counts nothing: there is no server in the middle, so scans are not recorded anywhere. If you need to know how many people scanned a poster, that is the job of an editable URL code, which redirects through this site and counts with the countries they came from. Printing advice for the physical side is collected in ten things to know before printing QR codes.
Two routes give you a link that lands on the review box rather than the map pin. In your Google Business Profile, the "Ask for reviews" button hands you a short link that ends in /review; copy that. The other route uses the listing's place id in an address of the form search.google.com/local/writereview?placeid= followed by your id, which you find with Google's own place id lookup. Paste either one into the field at the top of this page.
Then test it properly. Open the link on a phone, in a private window, signed out of every Google account, because the owner's logged-in device will happily open a page a customer never reaches. Multi-site businesses should check that each branch has its own link before anything goes to print, since a code on the Leeds counter pointing at the Sheffield listing is a mistake nobody spots for months.
Timing beats placement. A card by the till, a line on the receipt, a sticker on the paperwork handed over at the end of the job: these are read in the minute when the person is pleased with you. A poster in a corridor at the entrance is read by people who have not experienced anything yet.
One rule to keep in mind: you may not filter. Sending the code only to customers who already said something nice, or running a form that sends four and five star ratings to Google and quietly routes the rest to a private inbox, is review gating and it breaks Google's policy. Offering a discount or a free coffee in exchange is prohibited too. Same code, same question, every customer, including the ones who will be blunt.
The one that opens the review box directly. The short link from the "Ask for reviews" button in your Business Profile is the quickest, and a place id address works just as well. A plain Maps listing link is a weaker choice, because it drops people on the business page and they have to find the review button themselves.
Yes. Google requires a signed-in account for a review to post, and nothing on the printed side changes that. Most people on a phone are already signed in, so the box opens straight away. Anyone signed out sees a login prompt first, and a fair number of those will not continue.
No. Splitting customers so that happy ones reach Google and unhappy ones reach a private form is review gating, which is against Google's policy and can cost you reviews or the listing itself. Offering a discount for a review is prohibited as well. Ask everyone the same way.
Not from this code. The review link sits inside the printed pattern and nothing passes through a counter, so a scan leaves no trace on our side. Google's own profile statistics show reviews arriving over time, which is the measure that actually matters here. If you want the scans counted, make the code on the editable link page instead.
A printed code cannot be edited, so a new link would mean new cards. Review links are stable in practice: they hang off the place id, which survives a change of opening hours, phone number or even the business name. The address moves only if the listing itself is replaced, and in that case an editable link code saves the reprint.
A receipt is held about 30 cm away, so 2 to 3 cm across is workable if the thermal printer holds contrast and the quiet zone survives the cut. Test it on the actual printer, not on an office laser, because thermal paper smears fine detail more than people expect.
