Analytics & Measurement Check which GA4 channel a tagged link lands in
UTM Parameter
Tags added to the end of a URL — for example ?utm_source=newsletter&utm_medium=email — that tell analytics tools exactly where traffic came from. Consistent UTM tagging is essential for accurately attributing leads and revenue to specific campaigns.
Why it matters
Without consistent tagging, traffic from real campaigns quietly gets misclassified as generic "direct" or "referral" traffic, and campaign ROI becomes unmeasurable.
