container audit
GTM-NGFDD2C
232 tags, 591 KB delivered to every visitor — more than 90% of the 46,522 containers we have measured. Size is a description here, not a fault.
- 6 custom HTML tags carrying 38 KB of JavaScript. This runs on every page the container loads on.
- 1 third-party host reachable from its tags.

What we observed
A real browser loaded marieclairekorea.com 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
google-analytics.com — GoogleConsent
no consent gate responded on this page, so there was nothing to hold measurement back (banners are often shown only to visitors in certain regions, and this was not a European visit).
Third parties contacted
10 hosts — vjs.zencdn.net, cdn.jsdelivr.net, cdn.taboola.com, code.jquery.com, www.google-analytics.com, www.googletagmanager.com, gum.criteo.com, analytics.google.com, and 2 more
dataLayer events seen
gtm.js, gtm.dom, gtm.load
Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on marieclairekorea.com 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.
reviewUniversal Analytics tags still shipped (202)
202 Universal Analytics tags are still in the container.
WhyUniversal Analytics stopped processing data in July 2023. These tags still download and execute on every matching page, and send to an endpoint that discards them.
CheckNothing is being collected from these. Confirm the equivalent GA4 tag exists, then delete them.
Seenseen in 23.2% of 46,522 containers measured
reviewHardcoded http:// URL (1)
1 piece of custom code reference a plain http:// address.
WhyOn an https:// page the browser blocks or upgrades these. Blocked means the tag quietly stops working; upgraded only works if that host also serves https.
CheckCheck whether the hosts below still respond over https, and update the URLs.
Seenseen in 12.8% of 46,522 containers measured
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.

reviewNo consent signal in the container (1)
Nothing in this container sets, reads, or gates on a consent state.
WhyThe container itself neither sets a Consent Mode default, holds any tag back for consent, nor references a known consent platform. Either enforcement lives entirely outside GTM — where it cannot be audited from here — or tags fire regardless of what a visitor chose.
CheckIf a consent platform blocks scripts before GTM loads, this is fine — confirm that is actually the case. If not, tags are firing on a choice nobody recorded.

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 »

Sites observed loading this container. A container used across many hosts is a shared template; one on a single host is a bespoke build. Follow a site to see every container it loads.

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 »
