What print versus digital ROI tells you
Print versus digital ROI compares the return of QR codes on printed materials against QR codes shown on screens, such as websites, emails, and digital signage. The two channels behave differently, so comparing them fairly takes care.Print and digital often assist each other. A person may see print first and convert through digital later, so treat the split as guidance, not gospel.
How to compute print versus digital ROI
ROI for each channel = channel revenue minus channel cost, divided by channel cost, multiplied by 100. Compare the two results side by side using the same date range and the same definition of revenue.Illustrative example numbers, not real-world data: print returns 1,800 currency units on a 1,000 cost, giving (1,800 - 1,000) / 1,000 x 100 = 80% ROI. Digital returns 2,200 on a 1,000 cost, giving 120% ROI in this example. Digital wins here, but print may still be worth keeping for reach.
How to collect the data
Tag print and digital codes separately, keep costs separated by channel, and use the same revenue definition for both.Keep the raw counts, not just the final percentage. Raw counts let you recompute the metric if you later fix the definition, and they make it possible to spot a denominator problem, such as a week where exposures were estimated instead of counted. Store the counts in one place with the date range, the placements included, and the name of the person who pulled them. That small discipline turns a spreadsheet into an audit trail.
Reading the result
Never judge print versus digital ROI as a single number. Break it down by channel, placement, and campaign month. A campaign that looks average overall may be strong in one segment and weak in another, and the fix is completely different in each case. Compare the same placement against its own past, and compare different placements only when their audiences and contexts are genuinely similar. A short trend over four or more comparable periods is worth far more than a single snapshot, because it separates a real shift from weekly noise.Also check the relationship between print versus digital ROI and the metrics around it. If scans rise while conversions fall, the new scanners may be less interested visitors, or the landing page may have changed. If cost rises while print versus digital ROI stays flat, you are paying more for the same outcome. Metrics make sense in groups, not in isolation, and the habit of reading two or three together prevents most misreadings.
