Drupal's flexible architecture means standard analytics plugins rarely cut it. Audit your GTM and GA4 data layer for critical errors.
Every platform has its own failure modes. Here's what we see most often on Drupal — and what fixes each one.
Running multiple SEO, datalayer, and tracking modules simultaneously in Drupal often results in duplicated GA4 config tags firing on every page.
Enterprise Drupal sites heavily rely on Varnish or CDN caching, which can accidentally cache the data layer state and assign incorrect user IDs across sessions.
Capturing Drupal's deep taxonomy terms and custom entity fields in GA4 requires flawless integration between the backend data layer module and GTM.
The most common Drupaltracking complaint isn't broken tags — it's inflated revenue. When two GTM tags both fire on the same purchase event, GA4 records every real order twice. When both audits exist in your workspace, we add a 6th Integration chapter that catches this automatically (CROSS-003), plus 4 other bugs that live in the gap between GA4 and GTM. Included on every plan.
GTM ships a GA4 ID that no longer matches your property.
Events firing in GTM with no matching key event in GA4.
Two tags emitting the same event — the revenue-doubler.
Stop guessing if your data layer is correct or if plugins are duplicating your tags. Our engine scans your live Drupal installation and flags silent tracking failures.
