A practical workflow
Choose meaningful differences
Separate reception, receipts and personal follow-ups if each has a distinct purpose. Avoid making a campaign for every tiny artwork variation.
Name them clearly
Use the location and touchpoint in the campaign name. Staff should be able to choose the right link without opening every QR image.
Compare like with like
Review similar periods and note traffic differences. A busy reception naturally has more opportunities than a rarely used leaflet.
Avoid this mistake
Do not interpret campaign totals as a controlled experiment when audiences and timing differ.
What to check
Use observed visits, approvals and Google opens separately for each touchpoint.
Test the whole physical journey
Check both the printed code and the page behind it. A successful scan is only the entry point: the customer still needs to recognise the business, describe an experience and understand the Google handoff. Use the final material under ordinary lighting. Keep a copy of the approved artwork so a replacement does not accidentally introduce a different destination.
