container audit
GTM-PB2FNQ
50 tags, 6 custom scripts, 4 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 6 custom HTML tags carrying 9 KB of JavaScript. This runs on every page the container loads on.
- 4 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.
- 776 published versions — each one live for every visitor the moment it was published.

What we observed
A real browser loaded lendingtree.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
ibis.lendingtree.com — the site's own host, and googletagmanager.comMeasurement sent to
ibis.lendingtree.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
a consent platform is present, but our browser could not complete the accept step — so the before-and-after comparison did not run here. Google recorded
gcs=G111 (all granted).Third parties contacted
21 hosts — logx.optimizely.com, cdn.requestmetrics.com, a6207300250632192.cdn.optimizely.com, cloud.wordlift.io, unpkg.com, global.ketchcdn.com, api.wordlift.io, wsmcdn.audioeye.com, and 13 more

Where the data goes
Confirmed — a browser watched this site send measurement data to ibis.lendingtree.com, not to Google. observed on lendingtree.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 (2)
2 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
infoLoads JavaScript from another host (3)
3 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 (2)
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 »
