container audit
GTM-TFBK4FF
73 tags, 8 custom scripts, 5 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 8 custom HTML tags carrying 3 KB of JavaScript. This runs on every page the container loads on.
- 5 third-party hosts reachable from its tags.

What we observed
A real browser loaded secorsubaru.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
a consent banner was present and we accepted it. 9 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). 3 hosts appeared only after consent was granted. Google recorded
gcs=G101 (partial). 4 advertising hosts were contacted before anything was granted.Third parties contacted
25 hosts — pictures.dealer.com, cdn.complyauto.com, images.dealer.com, cdn.userway.org, platform.twitter.com, review-carousel-resource.kenect.com, ftm.fluencyinc.co, cdn2.webdamdb.com, and 17 more

Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on secorsubaru.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.
reviewWrites cookies directly (1)
1 piece 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
infoUses browser storage (1)
1 piece 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 (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 »

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 »
