What is UTM Builder
UTM Builder builds campaign links with utm_source, utm_medium and utm_campaign in the format GA4 classifies without falling into Unassigned, for Meta Ads, Google Ads, TikTok, email, WhatsApp, influencers and print. The same link becomes a static QR code that points straight to your page and never expires, even after it’s printed.
To check what’s already live, the auditor (in Portuguese) flags what GA4 will read wrong, and the guides explain the most confusing cases: Unassigned traffic, gclid or UTM and Meta URL parameters. There’s also the WhatsApp QR code and the Pix QR code generator (in Portuguese; Pix is Brazil’s instant payment system).
