What we observed
A real browser loaded poferries.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
Cookiebot answered its own API. Measurement fired beforehand but carried no identifier —
analytics_storage was denied, which is Consent Mode working as designed rather than a gap. 10 hosts appeared only after consent was granted. Google recorded gcs=G100 (all denied).Third parties contacted
25 hosts — cdnjs.cloudflare.com, fonts.googleapis.com, po-ecom-prod-xp-93-113810-cd-cdn.azureedge.net, code.jquery.com, www.paypal.com, dev.visualwebsiteoptimizer.com, widget.taggbox.com, www.googletagmanager.com, and 17 more
dataLayer events seen
general_params, gtm.js, gtm.dom, gtm.scrollDepth, gtm.load, cookie_consent_preferences, cookie_consent_statistics, cookie_consent_marketing

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.
No findings were raised for this container.
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 »
No third-party hosts were found in this container's tags.
Detected on
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 »
