Session

A session captures a user's interactions from website access to departure. Google Analytics ends sessions after 30 minutes of inactivity.

QR code scans almost always start new sessions - scanning a physical code and opening a browser is a new visit, not a continuation. QR code traffic registers clearly as session count increases.

Session behavior data is essential for QR code marketing measurement: session duration, pages per session, bounce rate, and conversion rate. UTM parameters (utm_source=flyer&utm_medium=qr&utm_campaign=spring2026) identify QR code sessions in analytics, enabling per-code quality comparison.
