Definition
What is UTM tracking?
UTM stands for Urchin Tracking Module. UTM parameters are tags appended to a link's query string that describe where a visit came from. There are five standard ones: utm_source identifies the referrer, such as a newsletter or a search engine; utm_medium identifies the channel, such as email, cpc or social; utm_campaign names the specific campaign the link belongs to; utm_term records the paid keyword; and utm_content distinguishes two links that otherwise point to the same place, such as a header and a footer button. They are read from the URL by the receiving site, so any analytics tool can interpret them. SourceTrack captures all five automatically and forwards them wherever you want.
What you get free
Things the tracker already computes.
Each of these is calculated client-side at zero marginal cost, which is why none of it sits behind a paywall.
First-touch AND current-touch
In every payload — not just current session.
AI-referral detection
ChatGPT, Perplexity, Claude — no competitor found in research offers this.
Bot-filtered before delivery
Automated traffic is dropped at ingestion, so it never reaches your CRM.
HMAC-signed payloads
Verify every delivery is genuinely from us.
Question
Before you ask.
Is this really unlimited?
UTM parameter capture has no limit. Tracked events are free up to 10,000/month — more than enough for most small sites, and there's no card required to find out.
