Stage 6
Persistent attribution storage
This stage makes sure every ad click and campaign tag follows the visitor from first landing page through to booking or enquiry, even if they browse multiple pages first.
What this stage must achieve
Google click IDs and UTMs are saved on first visit.
Attribution survives page changes and booking modal openings.
Every paid booking and enquiry keeps its original source data.
Private patient notes and treatment concerns stay excluded from marketing data.
Build checklist
Create browser-side attribution storage with expiry.
Capture first-touch and latest-touch attribution.
Use stored attribution when creating bookings and enquiries.
Add CRM visibility for attributed versus unattributed records.
Privacy rule: Only ad click IDs and campaign labels should be stored for marketing. Patient notes, symptoms, concerns, messages, and clinical details must never be sent to Google.
