container audit
GTM-M2HHDK7H
114 tags, 1 custom scripts, 11 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 1 custom HTML tag carrying 2 KB of JavaScript. This runs on every page the container loads on.
- 11 third-party hosts reachable from its tags — more than 80% of the 46,522 containers we have measured.
duplicate-ads-conversionis uncommon — under 4% 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 bankinter.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=G100 (all denied).Third parties contacted
25 hosts — www.youtube.com, www.googletagmanager.com, fonts.gstatic.com, googleads.g.doubleclick.net, static.doubleclick.net, cdn.cookielaw.org, i.ytimg.com, geolocation.onetrust.com, and 17 more

Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on bankinter.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
reviewSame Google Ads conversion defined more than once (1)
1 conversion action is defined by more than one tag.
WhyA conversion ID plus label identifies one action. Two tags carrying the same pair can report the same conversion twice, inflating conversion counts and the ROAS that bidding runs on.
CheckCheck whether both tags can fire on the same page. If they can, your Ads reporting is overstating this action and automated bidding is optimising against it.
Seenseen in 3.8% 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.

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 »
