Google Tag Manager Audit —
Find Broken Tags, Paused Triggers,
and Misconfigured Variables in 60 Seconds
Tag Assistant shows you what fired on one page. Our GTM audit tool inspects your entire container — every tag, trigger, and variable — and tells you what's broken before it breaks a campaign.

What We Check in GTM
Full container inspection across six categories — not just what fired on your last page load.
Paused Tags
Discovers tags that were paused during testing or incident response and never re-enabled. Paused tags are silent — they don't fire, don't error, and are easy to forget about. We cross-reference paused tags against your GA4 event data gaps.
Live Container vs Workspace Diff
Compares your published (live) container against any open workspace changes. Detects accidental partial publishes, tags in draft that should be live, and workspace drift that would cause inconsistency on next publish.
Tags Firing Before Consent
Identifies tags that lack proper consent gating — firing on All Pages or DOM Ready without a consent check. Critical for Consent Mode v2 compliance. We check all tags with advertising or analytics categories.
Unused Variables & Triggers
Catalogs variables and triggers that aren't referenced by any active tag. Unused entities add maintenance overhead, create confusion for new team members, and occasionally cause conflicts when similar names are added later.
Duplicate GA4 Configuration Tags
Detects multiple GA4 configuration tags with the same measurement ID, or tags using different IDs when only one is expected. Duplicate configs cause inflated session counts, doubled pageviews, and split data across properties.
Naming Convention Violations
Checks tags, triggers, and variables against naming convention patterns. Consistent naming is a prerequisite for maintainable containers. We flag mixed conventions (GA4 - Category - Action vs free-form names) that accumulate into maintenance nightmares.
The Hidden GTM Problems Analysts Miss
These issues won't show up as errors. They'll show up as mysteriously inflated conversions, impossible bounce rates, or a GDPR complaint.
Tags Firing on Every Pageview
CriticalPurchase confirmation tags using All Pages triggers instead of Thank You page URL patterns. E-commerce tags firing on every navigation inflate transaction counts by 10–40x in high-traffic setups. We detect trigger scope mismatches between intent and configuration.
event_callback Blocking Navigation
HighGTM's event_callback mechanism waits for tags to fire before completing form submissions or link clicks. If a tag's callback never resolves — due to an ad blocker or network failure — navigation hangs indefinitely. We flag tags on click/form triggers without timeout fallbacks.
Duplicate GA4 Tags From Migrations
CriticalThe most common migration mistake: adding a new GA4 configuration tag without removing the old Universal Analytics tag that was renamed. Both send data to different properties, but the same event data gets split — inflating some metrics, deflating others.
Unnecessary All Pages Triggers
MediumScroll depth tracking, video tracking, and element visibility tags that fire on every page regardless of whether the tracked element exists. Each unnecessary trigger adds page load overhead and sends irrelevant events to GA4 that pollute event reports.
Debug Mode Active in Production
HighGA4 tags with debug_mode set to true that got published from a testing container. Debug events appear in DebugView but also inflate real event counts and can expose PII in network requests. Easy to introduce, hard to notice without container inspection.
Custom HTML Tags Without Sandboxing
MediumCustom HTML tags that access document.cookie or window.localStorage without consent gating. These can set or read cookies before the user has consented, creating GDPR violations that bypass your CMP entirely.
How It Compares to Tag Assistant and Debug Mode
Existing tools inspect single pages. We inspect your entire container configuration and cross-reference it against real data.
| Feature | Tag Assistant | GTM Debug Mode | Manual Inspection | Check My Tracking |
|---|---|---|---|---|
| Scope | Single page, single session | Single page, requires debug URL | Entire container, but error-prone | Entire container + cross-referenced with live GA4 data |
| Access required | Chrome extension only | GTM access + Chrome | GTM full access | Read-only GTM + GA4 |
| Consent gating detection | No | Partial (page-level) | Manual — easy to miss | Yes — all tags checked |
| Time to complete | Per page (slow at scale) | Minutes per page | 1–3 hours | < 60 seconds |
| Finds paused tags | No | No | Yes, if you look | Yes — automated |
| Reproducible results | No — session-dependent | No — page-dependent | No — analyst-dependent | Yes — identical every run |
Your GTM Container Has At Least One Broken Tag
73% of GTM containers we audit have at least one paused or misconfigured tag that was silently failing. Find yours in 60 seconds.
