Are ad blockers ruining your ROAS? I engineered a dual-container (Web + Server) GTM setup for 100% data accuracy. What I Did: • Web: Integrated Cookiebot CMP for consent, custom HTML listeners for Calendly/CF7, and local storage scripts to boost match rates. • Server (Stape.io): Routed core events securely through the cloud. • APIs: Integrated Meta CAPI & TikTok Events API to bypass browser blocks. • Ads: Streamlined Google Ads & GA4 tracking. Result: High event match rates, lower CPAs, and clean 1st-party data.
