01 / How the audit works

Three layers, run in parallel. Configuration, behaviour, history.

L1 - API

Configuration

Reads attribution model, data retention, key event setup, and Smart Bidding readiness through the GA4 Admin and Data APIs , flagging the property-level misconfigurations that quietly delete data weeks before anyone notices.

Reporting Identity risk scoring

DDA data sufficiency check

Smart Bidding key event health

L2 - Crawl

Live behaviour

A headless browser loads your site, captures the dataLayer, and watches every tag fire , surfacing the gap between what the configuration claims and what real users actually see.

Consent Mode V2 signal timing

CMP vs tag race detection

DataLayer pollution analysis

L3 - Intelligence

Historical patterns

Looks at the last 8 weeks of data to find bot traffic, channel decay, and measurement drift that standard GA4 reports never flag.

Automated bot traffic detection

Cross-domain tracking gaps

7-day trend analysis

02 / Coverage

The five things most teams miss, in 229 expert checks.

Module 01

Property Configuration

Free

Property-level settings that quietly delete data, break attribution, or starve Smart Bidding of signal.

Two more lenses

Beyond the property. Two more lenses on the same audit.

GTM container audit

Read-only audit of your Google Tag Manager container: tags, triggers, variables, and the dependency graph that ties them together — so you can see what the container is configured to do before checking whether it does it.

Container config & versionsTag → trigger → variable graphRead-only, no container edits

Runtime tag-firing verification

A headless browser crawls real pages and records what actually fires. We match observed hits against the GTM config — flagging pre-consent and duplicate firing. Coverage is only what the crawl exercised, so configured-but-not-observed is not the same as broken.

Configured vs observed firingPre-consent & duplicate detectionEvidence = real network requests

Google's data-driven attribution needs at least 400 conversions per month. You currently have 387. If it drops further, GA4 silently falls back to last-click.

04 / What we find

The patterns showing up
in real audits.

60%

Typical gap between GA4 and Google Ads conversions across audited properties (Google, 2024).

74%

Of audited properties have at least one critical Consent Mode V2 misconfiguration.

Saved per property versus a manual audit - recovered as billable time for agency teams.

05 / Boundaries

Read-only by design.
Enforced at the OAuth scope.

No writes

We never modify your GA4 property.

Read-only OAuth scopes only. We cannot create, edit or delete events, audiences or settings - even if we wanted to.

analytics.readonly✓ enforced

No reach

We never touch unrelated data.

Scoped to Google Analytics. No Gmail, Drive, Ads or any other Google service. The handshake does not allow it.

No retention

We never store raw analytics.

Raw query payloads are discarded after processing. We keep audit outputs such as scores, findings, and generated reports rather than raw analytics exports.
