Referrers & UTM Analytics
Use referrer and UTM data to tell which physical placement or campaign produced a scan.
Referrers
Referrers indicate where browser traffic came from. Direct / QR is used when there is no referring page.
UTM values
UTM Source, Medium, Campaign, Content, and Term let you distinguish placements, channels, campaign names, variants, and audience identifiers.
Tip: Use a consistent naming convention — for example source=business-card, medium=qr, campaign=fall-2026 — so reports remain easy to filter and compare.
