container audit
GTM-P2ZM84W
16 tags, 4 custom scripts, 2 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 4 custom HTML tags carrying 3 KB of JavaScript. This runs on every page the container loads on.
- 2 third-party hosts 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.
duplicate-ga4-configis uncommon — under 5% 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 streamshark.io 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
load.t.streamshark.io — the site's own host, and googletagmanager.comMeasurement sent to
google-analytics.com — GoogleThe container is self-hosted; the measurement still goes to Google. The first-party path that a tagging server provides is not being used for the data itself.
Consent
7 hosts appeared only after consent was granted. Google recorded
gcs=G111 (all granted).Third parties contacted
25 hosts — go.ironbarkedge.com, fonts.googleapis.com, directory.cookieyes.com, cdn.jsdelivr.net, analytics.google.com, snap.licdn.com, stapecdn.com, connect.facebook.net, and 17 more

Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on streamshark.io 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.
reviewSame GA4 property configured more than once (1)
G-K0G5KYQLSB is configured by 2 separate tags.
WhyEach config tag initialises the property independently, so a single page view can be counted once per tag. Sessions, users and conversion rates all inherit the error.
CheckIf more than one of these fires on the same page you are double-counting. Compare against a known-good day, or check for a step change in traffic when the second tag was added.
Seenseen in 4.8% 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.

infoLoads JavaScript from another host (2)
2 pieces 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.

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 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 »
