container audit
GTM-59X4WML
32 tags, 6 custom scripts, 1 third-party host — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 6 custom HTML tags carrying 28 KB of JavaScript. This runs on every page the container loads on.
- 1 third-party host reachable from its tags.

What we observed
A real browser loaded fiat.com.tr 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
cmesc46g30008uxv1usqkonpx-signal.usehardal.com — not Google, at /sgtm/g/collectMeasurement is first-party; the container still loads from Google. These are separate decisions, and this is the more common of the two.
Forwarded to
GA4 ×4 — read from the measurement id, not the hostname
Consent
no consent gate responded on this page, so there was nothing to hold measurement back (banners are often shown only to visitors in certain regions, and this was not a European visit). 1 host appeared only after consent was granted. Google recorded
gcs=G111 (all granted).Third parties contacted
25 hosts — schema.milestoneinternet.com, cookielaw.emea.fcagroup.com, code.jquery.com, assets.adobedtm.com, livechatwidget-vega2.next4biz.net, www.googletagmanager.com, app.11sight.com, cmesc46g30008uxv1usqkonpx-signal.usehardal.com, and 17 more

Where the data goes
Confirmed — a browser watched this site send measurement data to cmesc46g30008uxv1usqkonpx-signal.usehardal.com, not to Google. observed on fiat.com.tr 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 (2)
2 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
infoUses browser storage (2)
2 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.

infoLoads JavaScript from another host (1)
1 piece 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.

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.

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 »
