A QR code is fast, but a scan alone does not guarantee a review. The post-scan screen and the path to Google matter most.
Short recommendation
The strongest setup is a QR code connected to a clear post-scan screen, a good CTA, and analytics.
A QR code is only the entrance
You can generate a QR code in seconds, but conversion depends on customer intent, the message, and the next screen.
That is why SpinReview treats the QR code as the start of the review flow, not the entire product.
What to measure
The important signals are scans, QR placements, next-step clicks, and the consistency of new reviews.
Those signals help move QR codes to places where customers actually respond.
