Free tools and reference docs for teams who want consistent UTM tagging, correct GA4 channel grouping, and attribution models they can actually explain.
Use the UTM Enforcer to build campaign links with consistent source, medium, and campaign values your whole team agrees on.
Google Analytics reads your UTM values and maps each session to a default channel — Paid Search, Email, Organic Social, and more.
Your chosen model — last-click, first-click, or data-driven — decides which touchpoints get credit for each conversion.
A complete guide to how GA4 assigns credit — models, lookback windows, the five UTM parameters, channel grouping rules, and naming conventions your whole team can follow.
Build compliant tagged URLs from controlled source/medium lists, audit existing URLs for errors, bulk-edit via CSV, and keep a local history of everything you've created.
GA4 uses your UTM values to classify traffic. Wrong mediums push paid clicks into Organic or Direct — skewing every report.
First-click, last-click, and data-driven attribution tell different stories. Know which to use and what each one hides.
Controlled source and medium lists plus slug-formatted campaign names keep data clean even when many people are tagging URLs.
Both tools run entirely in the browser. No sign-up, no install, no data sent anywhere. Works offline after the first load.
Paste any URL into the Auditor and get instant validation: missing params, wrong case, forbidden mediums, non-slug values.
Pre-fill the builder from a link so you can share a partially-completed URL template with a teammate or embed in a brief.
