container audit
GTM-T86XT76
53 tags, 16 custom scripts, 5 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 16 custom HTML tags carrying 5 KB of JavaScript — more than 70% of the 46,522 containers we have measured. This runs on every page the container loads on.
- 5 third-party hosts reachable from its tags.

What we observed
A real browser loaded ij.org 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
a consent platform is present, but our browser could not complete the accept step — so the before-and-after comparison did not run here.
Third parties contacted
25 hosts — fonts.googleapis.com, static.cloudflareinsights.com, www.youtube.com, js.hs-scripts.com, www.googletagmanager.com, widgets.guidestar.org, i.ytimg.com, matchbox.hepdata.com, and 17 more

Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on ij.org 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 (1)
1 Universal Analytics tag is 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
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.
Seenseen in 52.1% 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.

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 »
