The Professional Tracking Stack

Conversion tracking quietly broke for professional services in 2025 and 2026. Consent Mode v2 became mandatory in the EEA. Meta restricted lower-funnel events for healthcare and behavioral health accounts. Third-party cookies are gone in Chrome. Most law firms, medical practices, and home service businesses are flying blind on attribution and do not know it. This is the playbook that fixes it: GA4, Meta CAPI, Google Ads Enhanced Conversions, CallRail, and consent management, set up the way your industry's rules require, with a companion git repo that has the working code.

• GA4 plus GTM plus Consent Mode v2: the foundation every professional services site needs in 2026
• Server-side conversions via Meta CAPI and Google Ads Enhanced Conversions without leaking PHI or PII
• Vertical-specific patterns for doctors (HIPAA), lawyers (state bar rules), and home services (call-driven)
