container audit
GTM-KZXSKCW8
213 tags, 15 custom scripts, 1 third-party host — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 15 custom HTML tags carrying 21 KB of JavaScript — more than 70% 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.

What we observed
A real browser loaded lbs.de 2 months 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
s-tag.lbs.de — not GoogleMeasurement is first-party; the container still loads from Google. These are separate decisions, and this is the more common of the two.
Forwarded to
GA4 ×3 — read from the measurement id, not the hostname
Consent
a consent banner was present and we accepted it. Nothing measured until it was granted — no analytics or advertising hit left the page beforehand, and 3 fired afterwards. That is the outcome consent is meant to produce. 5 hosts appeared only after consent was granted. Google recorded
gcs=G111 (all granted).Third parties contacted
10 hosts — bt.fraud0.com, cdn.trustcommander.net, privacy.trustcommander.net, privacy.commander1.com, www.googletagmanager.com, connect.facebook.net, www.google.com, ad.doubleclick.net, and 2 more
dataLayer events seen
event.carousel, fraud0, f0_event_invalid_traffic, gtm.js, pageview, gtm.dom, gtm.load
Where the data goes
Confirmed — a browser watched this site send measurement data to s-tag.lbs.de, not to Google. observed on lbs.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.
infoOne variable that a great deal depends on (74)
"trueUrl" is read by 74 tags and triggers — more than anything else in this container.
WhyGTM shows you where a variable is defined, never how much depends on it. Editing this one touches a large share of the container at once, and whatever breaks will surface somewhere that looks unrelated to the change.
CheckBefore changing it, check what reads it. If it feeds both measurement and consent or routing logic, split those uses apart first.
Seenseen in 10.1% of 46,522 containers measured
infoConsent configuration detected (2)
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.
Seenseen in 44.6% of 46,522 containers measured
infoLoads JavaScript from another host (1)
1 piece of custom code fetch and run JavaScript from another host.
WhyWhatever that host serves executes with full access to the page — it can read the DOM, cookies and form fields. The code is not in this container, so it can change at any time without any change here.
CheckConfirm you recognise every host below and that someone owns the relationship. A host you cannot name is the one to chase.
Seenseen in 54.4% of 46,522 containers measured
infoUses browser storage (1)
1 piece of custom code read or write localStorage or sessionStorage.
WhyBrowser storage persists across visits and is not covered by cookie consent tooling, so it is easy to overlook when auditing what you keep on a visitor's device.
CheckConfirm nothing personal is being kept there, and that it is covered by your privacy notice.

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 2 months 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 »
