container audit
GTM-PCV5MMWZ
43 tags, 13 custom scripts, 2 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 13 custom HTML tags carrying 5 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.

What we observed
A real browser loaded stihlusa.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
sgtm.stihlusa.com — the site's own host, and googletagmanager.comMeasurement sent to
sgtm.stihlusa.com — not GoogleMeasurement runs through the site's own infrastructure. Part of the tag library still comes from Google, which is normal — the two are loaded separately.
Forwarded to
GA4 ×5 — read from the measurement id, not the hostname
Consent
OneTrust answered its own API. 5 measurement hits left the page before it was granted, carrying a client id (whether that is permitted depends on jurisdiction, and this was not a European visit). 9 hosts appeared only after consent was granted. Google recorded
gcs=G111 (all granted). 8 advertising hosts were contacted before anything was granted.Third parties contacted
25 hosts — rum.hlx.page, cdn.cookielaw.org, geolocation.onetrust.com, edge.curalate.com, www.googletagmanager.com, js.stripe.com, 252092-stihl-b2camer.adobeioruntime.net, cdn.trkkn.com, and 17 more

Where the data goes
Confirmed — a browser watched this site send measurement data to sgtm.stihlusa.com, not to Google. observed on stihlusa.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.
infoUses browser storage (7)
7 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
infoConsent configuration detected (3)
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 »
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 »
