Cross-domain tracking breaks when a user moves between your main site and a separate checkout domain, payment gateway, or subdomain — each domain treats the user as a new session, inflating session counts and breaking purchase attribution. We diagnose your cross-domain tracking gaps, configure GA4's cross-domain measurement correctly, add linker parameters to all cross-domain links, and verify session continuity is maintained through the complete purchase path.

Frequently Asked Questions

Signs: high direct traffic landing on checkout or thank you pages, inflated session counts, purchase events attributed to 'direct' rather than the original traffic source, or GA4 showing users as 'new' at checkout.
GA4 passes a _gl parameter in the URL when linking between domains. The receiving domain reads this parameter to continue the same session. We configure GA4's domain list and GTM to decorate all cross-domain links.
iFrames (Stripe Elements, PayPal in-page) don't need cross-domain setup — the parent page remains the same domain. Cross-domain issues arise only when there's a full page redirect to a different domain.
Yes — we configure the linker parameter on your checkout link to the gateway, and verify that the gateway's return URL preserves the parameter. Some gateways strip URL parameters, requiring alternative approaches.
Cross-domain issues primarily affect session-based analytics (GA4). Meta Pixel and Google Ads use cookies set on their own domains and aren't affected by your cross-domain setup in the same way.
