Review QR codes.
Ask once, change where it goes later.
A QR code that opens your review page, on a card, a receipt, a window or a van. Point it at Google, TripAdvisor, Yelp or your own site today and somewhere else next year, without reprinting a thing.
Ask everyone, the same way
A printed review code is fine. Google documents making one. What is not fine is sorting people first: routing the happy ones to your public profile and the unhappy ones to a private form. That is review gating, and the penalty can reach every review on the profile, not only the ones collected that way.
Neutral ask. Everyone. Nothing in exchange.Where the code should point
One code per destination. A dynamic code means none of these choices is permanent.
Google Business Profile
The default for anyone with a physical presence or a service area. Google publishes a short review link and a QR code for it, which you can use as the destination rather than sending people to search for you.
TripAdvisor, Yelp and the trade directories
Worth a second code rather than a second sign. Which one matters is industry-specific, and the honest answer is usually whichever one your customers already read.
Your own site
For a direct-booking property or a business that publishes testimonials. You control the page, so you control what happens after the scan.
A private feedback form
Its own code, shown to everyone, never as a fork in the review path. Useful for catching the broken thing before it becomes the review, as long as it is not conditional on how you expect someone to feel.
Review links change more than you think
This is the case for making a review code dynamic rather than encoding the URL into the pattern. The printed artwork is the expensive part, and it is the part you cannot change.
Where it goes matters more than the code
Scans cluster around the moment someone is already pleased and already holding their phone. Everything else is a code nobody looks at.
