container audit
GTM-WV238FK
This container can hand execution to 13 third parties — more than 90% of the 46,522 containers we have measured. Each serves code it controls, which can change at any time.
- 15 custom HTML tags carrying 18 KB of JavaScript — more than 70% of the 46,522 containers we have measured. This runs on every page the container loads on.
- Measurement runs through a server container on its own domain — the mark of a mature setup, and rarer than the tooling vendors imply.
- 761 published versions — each one live for every visitor the moment it was published.
inner-htmlis uncommon — under 6% 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 suitsupply.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
OneTrust answered its own API. Nothing measured until it was granted — no analytics or advertising hit left the page beforehand, and 3 fired afterwards. That is the outcome consent is meant to produce. 10 hosts appeared only after consent was granted. Google recorded
gcs=G111 (all granted).Third parties contacted
25 hosts — cdn.cookielaw.org, www.google.com, www.gstatic.com, browser-intake-datadoghq.eu, apollo-router-production.politesmoke-d99eed9b.westeurope.azurecontainerapps.io, geolocation.onetrust.com, privacyportal-eu.onetrust.com, cdn.segment.com, and 17 more

Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on suitsupply.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.
reviewdocument.write (3)
3 pieces of custom code call document.write.
Whydocument.write blocks the HTML parser while it runs, and browsers ignore it entirely once the page has finished parsing — so an async-loaded tag using it can silently do nothing.
CheckIf these tags fire on page load they are costing render time; if they fire later they may not be working at all. Worth confirming the tag still does what it was added to do.
Seenseen in 18.4% of 46,522 containers measured
reviewWrites cookies directly (3)
3 pieces 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.
Seenseen in 21.2% 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 innerHTML (1)
1 piece of custom code assign to innerHTML.
WhyAssigning innerHTML parses the string as HTML. If any of it comes from the URL, the page or a cookie, that is a script-injection route into your own site.
CheckCheck whether the assigned value is a fixed template or built from something a visitor can influence.
Seenseen in 5.7% of 46,522 containers measured
infoUses browser storage (5)
5 pieces of custom code read or write localStorage or sessionStorage.
WhyBrowser storage persists across visits and is not covered by cookie consent tooling, so it is easy to overlook when auditing what you keep on a visitor's device.
CheckConfirm nothing personal is being kept there, and that it is covered by your privacy notice.
Seenseen in 23.3% of 46,522 containers measured
infoLoads JavaScript from another host (4)
4 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.
Seenseen in 54.4% of 46,522 containers measured
infoConsent configuration detected (4)
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.

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 »
