How it works

How your conversion data flows

Every lead and sale is captured once on your site, checked on your own server, then sent to each ad platform.

  • Browser and server copies share one event ID, so each platform counts the conversion once
  • Consent Mode v2 decides what each tag is allowed to send
  • Click IDs (gclid, fbclid, ttclid) are kept in first-party cookies

FAQ

Advanced Conversion Tracking: FAQ

What is server-side tracking and why do I need it?

Server-side tracking sends conversion data from a server container (for example GTM server-side on Stape or Google Cloud) instead of only the visitor's browser. It reduces data loss from ad blockers and iOS privacy restrictions, sets first-party cookies and gives ad platforms more reliable signals.

Do I still need client-side pixels if I use server-side tracking?

Yes, in most cases. The best setup runs browser pixels and server events together, with event deduplication, so platforms like Meta and Google Ads receive complete data without counting conversions twice.

Can you track phone calls, WhatsApp chats and offline sales?

Yes. I set up click-to-call and Google Ads call tracking, WhatsApp, Messenger and chatbot tracking, and offline conversion tracking that sends qualified leads and closed deals from your CRM back to Google Ads and Meta.

Can you track bookings and payments inside iFrames or on other domains?

Yes. I configure iFrame, cross-domain and subdomain tracking for tools like Calendly, Acuity, Typeform, JotForm, third-party checkouts and payment gateways, and stitch sessions so the conversion is credited to the right campaign.

Is your tracking setup privacy compliant?

Yes. I implement Consent Mode V2 and build tracking that respects GDPR and CCPA requirements, so you can keep measuring performance while staying compliant.

Why do Google Ads and GA4 show different conversion numbers?

They use different attribution models, conversion windows and counting rules, and broken tags make the gap worse. I diagnose the discrepancy, align the settings and fix the tracking so both platforms tell a consistent story.
