Tracking form submits and click-to-call taps to the original traffic source

Pageview analytics show that visitors arrived but not which ad, keyword, or search produced a lead, because the conversion happens in an inbox or phone log. The article argues that the fix is to store the first-touch source on a visitor's initial landing and attach it when a contact form is submitted or a tel: link is tapped. It describes four useful signals: UTM parameters, the document referrer, and the gclid and fbclid click IDs from Google and Meta ads. A simplified JavaScript example shows how to save this data locally and add it as hidden form fields or send it with a beacon. The author cautions that the sketch needs a server, consent handling, and a way to detect AI-assistant referrals, and should not be treated as a complete identity system.
