Free, read-only audit of a website's marketing tracking from its public URL. No account, no OAuth, no API key, no
browser extension. It checks Google Tag Manager, GA4, Google Ads conversion tags, Meta Pixel, TikTok, Pinterest,
the cookie banner, Consent Mode v2 and server-side tagging (Stape, Addingwell…). It returns a score out of 100,
prioritised fixes, what is already in place and what cannot be verified from outside.

Reports are written in French (the tool is built for French-speaking advertisers in France, Belgium and Switzerland).
Field names of the structured output are in French too; see examples.
Why "no account" matters
Most tracking audit tools and MCP servers read your Google Tag Manager or GA4 configuration through Google OAuth, or
need a browser extension and someone who can read network requests. This tool only uses what any visitor can see:
the page you name and its public Google Tag Manager containers. You can test your own site in seconds, a prospect's
site, a competitor's site, or your site before giving anyone access to your accounts.
What it checks (13 points, 4 families)
| Family | Points |
|---|
| Foundations (20) | Google Tag Manager, duplicate tags, hard-coded tags |
| Measurement (25) | GA4, ad platforms (Google Ads, Meta, TikTok, Pinterest), Google Ads click linking, enhanced conversions / Conversions API |
| Consent (25) | Cookie banner (CMP), Consent Mode v2 (default state, the 4 v2 signals, consent granted by default) |
| Resilience (30) | First-party loading, server-side tagging, measurement subdomain, Safari cookie lifetime (ITP) |
Points that do not apply are left out of the score; points that cannot be verified from outside count for half.
When a site cannot be read (anti-bot protection, JavaScript-only page), the result is inconclusive: the tool
never invents a score.
Use it from an AI assistant (MCP)

Limits
- Static reading: the tool reads the page and the published GTM containers; it does not click the cookie banner,
run a checkout, or see what the server-side container forwards. Purchase events and data received by the platforms
must be checked in an end-to-end audit.
- Rate limits: 30 new analyses per hour per IP address; recent results are served from a 6-hour cache.
- Sites behind anti-bot protection may return an inconclusive result.
Data
The server receives the site address to test and technical metadata, never your conversation. No account access, no
email. Details (collection, storage in Germany, retention): https://dhsdigital.eu/tracking/assistants-ia/ (section
« Quelles données le connecteur collecte-t-il ? »).
