Which printed spot is actually working? Comparing QR code placements
ON THIS PAGE
Give each placement its own QR code
You are ordering another batch of table tents and want to know whether customers use them. If the tents and window decal use the same QR code, their scans are counted together. You cannot separate those physical placements from the total later. Create distinct QR codes, give them recognizable names and record where each is deployed.
They can point to the same destination. Keep the message and final action comparable if the question is where the QR code is placed.
Compare the same period
Basic counts can show which item has recorded more activity. In the dashboard, open Performance, choose QR codes and select the items in Compare assets. The time chart helps distinguish steady activity from a brief spike.
Use the same dates. Note when a placement was removed or covered, when opening hours changed, or when one item received extra promotion. A missing period is not a confirmed zero.
Account for exposure
A table used by hundreds of diners and a window passed by a dozen pedestrians do not offer the same opportunity to scan. More scans alone does not establish a better design or a higher scan rate. To calculate a scan rate, you also need a credible count of opportunities to scan, such as how many cards you handed out.
These placements are observed in their usual settings. It can suggest a practical next step, such as inspecting an unused sign or moving a QR code into view. It does not prove that placement caused a sale.
When you check the table tents, sit where a guest sits. Can they reach the menu comfortably? Your comparison can help you put useful information where people need it.
Avoid reacting to small differences
Nine scans versus twelve is not enough by itself to justify reprinting. Consider the cost of the decision, the exposure, normal variation and whether the difference persists. No fixed number of days makes every comparison reliable.
Before retiring a quiet item, check whether it was actually deployed and whether its destination still works. Lack of activity alone is not a system incident.
Common questions
How do I compare two placements?
Use a separate QR code for each placement, name them clearly and compare recorded scans over the same period. Record differences in exposure and conditions.
Is a placement comparison an A/B experiment?
Not by itself. Different physical locations can have different exposure. Formal outcome experiments need a defined assignment method, objective and sufficient eligible evidence.
