AUTOMATED BROWSER SIMULATIONS

Stop guessing if your GA4 revenue matches Shopify.

Shopify theme updates, app installs, and CMP banners silently break GTM triggers. AuditTags runs an automated headless-browser simulation that validates GA4, GTM, and Consent Mode — without manual debugging in Preview Mode.

EXAMPLE FINDING

Purchase Event Double-Firing

GA4 purchase event fired twice on checkout completion, inflating revenue metrics by ~2×.

Found: event: "purchase" count: 2
transaction_id: "txn_4428"
Impact: Revenue overcounting by 100%

Built for Shopify & DTC

Real browser execution, not static checks

90s-grade consistency — verified nightly

Used by agencies & performance teams

Your tracking breaks more often than you think — and rarely where you expect.

Shopify theme pushes modify HTML structure

→ GTM triggers stop firing

App installs inject duplicate tracking scripts

→ Revenue metrics double-count

CMP vendors block scripts until consent

→ But GA4 events still fire incorrectly

Purchase events double-fire or fail to fire entirely

→ Revenue data becomes unreliable

Manual debugging is slow and inconsistent

→ Issues vary across devices and regions

GA4 Validation

Measurement IDs detected, event consistency by flow, duplicate hit detection.

GTM Integrity

Container detection, tag firing consistency, blocked tags, missing triggers.

Consent Mode v2

gcs parameter inspection, pre/post-consent behavior validation.

Duplicate Tracker Detection

Facebook, TikTok, Klaviyo, ad scripts, theme-injected extras.

Shopify Signal Validation

Platform signature detection, network pattern matching.

Network Evidence

All collected hits with timestamp, status, and source.

PDF + JSON Output

Generated on-demand, deterministic, uses the engine's canonical presentation summary.

Free Pre-Check shows 3 essential checks — and locks the remaining 44.

The pre-check is intentionally limited. If the first 3 checks are green, that does not mean your site is healthy.

A clean pre-check only confirms that GA4, GTM, and a CMP are present on page load. It does not validate event consistency, duplicate tracking, consent behavior, or purchase flow integrity.
