What benchmarks can and cannot do
Campaign ROI compares the value a QR campaign produces against what it cost. It is the number that decides whether a campaign deserves more budget, a redesign, or retirement.Benchmarks for campaign ROI are tempting because they promise a shortcut: one number that tells you whether you are doing well. In practice, a benchmark is only as useful as its definition, and definitions vary widely. One source may count every scan, another may count only unique scanners, and a third may measure a different placement type entirely. Two benchmarks that disagree are not a puzzle to solve; they are a signal that the underlying measurements differ. Treat any benchmark as a rough reference, never as a verdict.
Why benchmarks for campaign ROI vary
Benchmarks vary for reasons that have nothing to do with quality. Placement changes everything: a code at a checkout behaves differently from a code on a poster. Audience matters too: existing customers scan for different reasons than strangers do. Offer strength, season, device mix, and time of day all shift the number. Even the definition shifts it: changing the denominator or the time window changes the result without changing the campaign at all. ROI hides timing. A campaign can look weak in week one and strong by week six, so judge it over its full life.This variation is why copying a published benchmark as a target is risky. You may be comparing your menu code against someone else's checkout code, or your first month against their twelfth. The gap you see may be a measurement gap, not a performance gap, and chasing it can lead you to fix things that were never broken.
How to build your own baseline
Your own baseline is the benchmark that matters most, because it shares your definition, your placements, and your audience. Build it in four steps. First, write down the definition: ROI = revenue minus cost, divided by cost, multiplied by 100. A result of 0% means the campaign broke even. A result of 100% means it returned twice what it cost. Second, measure it for a fixed period on a stable placement and record the raw counts, the date range, and the method. Third, repeat the measurement for two or three more comparable periods. Fourth, use the range you observed as your baseline, not a single point, because a range respects normal variation.Illustrative example numbers, not real-world data: revenue of 5,000 currency units minus a cost of 2,000 gives 3,000, and 3,000 / 2,000 x 100 = 150% ROI. If revenue falls to 2,000 with the same cost, ROI becomes 0% and the campaign only broke even.
Once the baseline exists, judge new results against it. A result inside the baseline range is normal variation. A result outside the range for two consecutive periods is a signal worth investigating. This approach is slower than copying a published number, but it is honest, and it improves as your own history grows.
