container audit
GTM-MT2LZPB
79 tags, 34 custom scripts, 1 third-party host — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 34 custom HTML tags carrying 21 KB of JavaScript — more than 80% of the 46,522 containers we have measured. This runs on every page the container loads on.
- 1 third-party host reachable from its tags.
- Measurement runs through a server container on its own domain — the mark of a mature setup, and rarer than the tooling vendors imply.
- 369 published versions — each one live for every visitor the moment it was published.

What we observed
A real browser loaded centerparcs.de a month ago and recorded every request it made. This is what happened, as distinct from what the container is configured to do. It is one page load — anything that fires only deeper in the site did not fire here.
Container loaded from
googletagmanager.com — GoogleMeasurement sent to
www.centerparcs.de — not Google, at /metrics-de/ecbj3eMeasurement is first-party; the container still loads from Google. These are separate decisions, and this is the more common of the two.

Consent
Didomi answered its own API. Nothing measured until it was granted — no analytics or advertising hit left the page beforehand, and 7 fired afterwards. That is the outcome consent is meant to produce. 10 hosts appeared only after consent was granted. Google recorded
gcs=G111 (all granted).Third parties contacted
25 hosts — static.centerparcs.com, ssa.centerparcs.com, ic.centerparcs.com, s.go-mpulse.net, photo.centerparcs.com, www.gstatic.com, c.go-mpulse.net, sdk.privacy-center.org, and 17 more

Where the data goes
Confirmed — a browser watched this site send measurement data to www.centerparcs.de, not to Google. observed on centerparcs.de More info »
Findings
Ordered by consequence. review has a concrete cost when it bites; info is real but depends on your setup. Seen is how common it is across the containers we have measured — reported separately on purpose, because common and harmless are different claims.
reviewWrites cookies directly (1)
1 piece of custom code set cookies in code.
WhyCookies set this way bypass GTM's consent settings, because the consent checks live in the tag templates rather than in raw JavaScript.
CheckIf any of these cookies are used for analytics or advertising, confirm they are still gated on a consent decision.
Seenseen in 21.2% of 46,522 containers measured
infoConsent configuration detected (3)
The container declares one or more consent signals.
WhyConsent handling is present in the container. This describes what the artifact declares; what actually happened on the page is measured separately, above.
CheckConfirm these settings match the consent policy you intend to enforce, and compare them with the before-and-after observation.

Third parties it can reach
Each host is a party that can execute code or receive data in a visitor's browser. Follow one to see who else loads it. More info »
What the custom templates can do
Custom templates are third-party code shipped inside the container. Injecting scripts and running page globals is ordinary for them — most tag templates need it to work — so this is an inventory, not a warning. It lists the capability each template declares so you can match it against templates you meant to install.

Re-audit
This reading is from a month ago. A container can be republished at any time, and nothing here updates on its own — a fresh read is the only way to know whether it still says this. Running it again replaces this page in place, so the link keeps working.
Put this container under version control. Tagora exports it to a repository you own, so every change arrives as a pull request. How it works »
