A/B Testing QR Codes
Definition: A/B testing QR codes means running two variants of a placement, design, or offer with separate dynamic codes so scan data shows which performs better.
Because each dynamic code keeps its own scan log, print is finally measurable in the way digital advertising has always been. The discipline is the same as any experiment: change exactly one variable, run both variants over the same period and audience, and give it enough volume that the difference is not noise. Useful tests include placement (counter versus door), call-to-action wording, code size, colour versus black, and destination page. Avoid testing two things at once and avoid stopping early because an initial gap looks convincing — early scan data swings wildly at low volumes.
Key points
- One dynamic code per variant so scans stay separately attributed
- Change a single variable per test
- Run variants over the same days and audience
- Wait for meaningful volume before calling a winner
- Log every test so results are not relearned each campaign
Frequently asked questions
Can you A/B test printed materials?
Yes, using separate dynamic QR codes on each variant so you can compare scan counts directly.
How many scans do I need to decide?
Enough that the gap is far larger than daily fluctuation — often a few hundred per variant for modest differences.
What is the most valuable thing to test?
Placement usually beats design. Where the code sits affects scans more than what colour it is.
