About This Service
What Is GA4 Cross Domain Tracking?
Cross-domain tracking ensures that users moving between your different domains are recognised as the same session rather than counted as new visits each time. Without cross-domain tracking, your conversion funnel breaks at every domain boundary and last-click attribution credits the wrong source for conversions that began on a different domain.
Configuring cross-domain tracking in GA4 requires adding all relevant domains to the Google Analytics cross-domain list in the data stream settings, and verifying that the linker parameter is being passed correctly in the URL when users navigate between domains. Payment processors and external booking platforms that do not share your GTM container require a different approach.
Adslytics configures cross-domain tracking with a full boundary test, verifying in DebugView and Real-time reports that sessions are maintained correctly across every domain transition. You receive a written record of all configured domains, the verification test results, and instructions for adding new domains to the configuration if your domain estate expands.

What Clients Say
"We'd been running GA4 for six months with barely any useful data — missing events, broken funnels, no purchase data. After the audit and rebuild we finally have accurate revenue figures and a proper conversion funnel. Completely transformed how we report."
Sarah Kim
Head of Marketing
"The GA4 migration from Universal Analytics was blocking our whole reporting stack. The team handled the full migration, set up matching custom events and built us a Looker Studio dashboard that replaced our old UA reports within days."
David Marsh
Growth Manager
"Our GA4 was technically installed but 90% of the custom events we needed weren't firing. After the setup service we have scroll depth, video plays, form submissions and checkout steps all tracking correctly. Now we can actually optimise."

Marketing Director
