Google Analytics

Google Analytics (GA) is Google's web analytics tool. The current version, GA4, measures page views, users, session duration, and conversions in real time. Approximately 55% of websites worldwide use it. For QR code marketing, GA combined with UTM parameters is essential for quantifying offline campaign effectiveness.

To measure QR code traffic in GA4, append UTM parameters to the QR code URL. Settings like utm_source=qr_code&utm_medium=offline&utm_campaign=spring_flyer let you isolate QR-sourced traffic in the Traffic Acquisition report, tracking post-scan behavior through to conversion.

GA4's event-based measurement model pairs well with QR marketing. It automatically tracks scans (page views), scrolls, clicks, form submissions, and purchases as events. Funnel analysis reveals drop-off points, and comparing QR landing page conversion rates against other channels (search, SNS, ads) evaluates relative QR campaign effectiveness.
