container audit

GTM-TJ3SP8

3 tags, 2 custom scripts, 3 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).

2 custom HTML tags carrying 1 KB of JavaScript. This runs on every page the container loads on.
3 third-party hosts reachable from its tags.

What we observed

A real browser loaded gol24.pl 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 — Google

Measurement sent to google-analytics.com — Google

Consent Didomi answered its own API. Measurement fired beforehand but carried no identifier — analytics_storage was denied, which is Consent Mode working as designed rather than a gap. 10 hosts appeared only after consent was granted. Google recorded gcs=G100 (all denied).

Third parties contacted 25 hosts — s-ams.ppstatic.pl, sdk.privacy-center.org, s-nsk.ppstatic.pl, fonts.googleapis.com, securepubads.g.doubleclick.net, sentry.grtech.pl, atm.api.dmp.nsaudience.pl, www.googletagmanager.com, and 17 more

Where the data goes

Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on gol24.pl 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.

infoConsent configuration detected (1)

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

infoVendor IDs written into custom code (1)

1 vendor ID is pasted directly into custom HTML rather than held in a variable or template.

WhyChanging a property, pixel or account then means editing every tag that mentions it, and any one that gets missed keeps sending to the old destination indefinitely.

CheckFine if the ID never changes. If you have ever migrated a property, check that none of these still point at the old one.

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 this audit describes

Containers change. These findings describe one specific artifact, and you can re-fetch it to check this reading.

Container	`GTM-TJ3SP8`
Published version	`38` — the identity of this configuration. It changes only when someone publishes.
Read at	2026-08-22 13:34:40 UTC (2 months ago)
Source	`https://www.googletagmanager.com/gtm.js?id=GTM-TJ3SP8`
Body checksum	`789fd5b62679396d3a37e2afdf6063a1d58772b7b8c77b84d16f38d788b6a81e` Evidence of the exact bytes we read, not an identity: Google varies the response per request, so re-fetching an unchanged container yields a different checksum. Compare the published version instead.

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.
