Ad tracking (C15)

Attribution fields after navigation

This guide helps you act on one scan finding. It is not legal advice or a compliance verdict.

What to fix

Keep attribution fields/storage intact after in-site navigation (SPA builders and cached fragments often reset them).

Persist UTMs in first-party cookies/storage on first landing (Grabber).
Re-bind hidden fields on Elementor/page-builder “page change” events, or prefer full page loads between steps.
Disable fragment caching for the form block if the cache serves empty hidden fields.
Test a two-page funnel before scanning.

Re-scan a multi-page path and confirm C15 still looks correct after navigation.

Scan the same URL again, then compare this check with your previous report.
