container audit
GTM-P43LJK9
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.
evalis uncommon — under 1% of the containers we have measured have it. That is context rather than a verdict: a server container is rarer still and is a sign of a mature setup. What it means is in the finding itself.

What we observed
A real browser loaded h1g.jp 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.

Where the data goes
Nothing fired — we loaded the page and no tag library or measurement request ran, which usually means a consent banner held everything back. The container below still describes what would run once it does. observed on h1g.jp 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.
revieweval() (1)
1 piece of custom code call eval().
Whyeval turns a string into executing code. If any part of that string comes from the page, the URL or a cookie, whoever controls that input controls the code.
CheckTrace where the evaluated string comes from. A fixed literal is harmless; anything derived from user-controllable input is not.
Seenseen in 0.5% 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.

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 »
