container audit
GTM-MGPK7TL
58 tags, 5 custom scripts, 11 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 5 custom HTML tags carrying 7 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.
inner-htmlis uncommon — under 6% 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 commonapp.org 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. Measurement fired beforehand but carried no identifier —
analytics_storage was denied, which is Consent Mode working as designed rather than a gap. 7 hosts appeared only after consent was granted. Google recorded gcs=G100 (all denied).Third parties contacted
13 hosts — www.googletagmanager.com, ebs.commonapp.xyz, cdn-cookieyes.com, log.cookieyes.com, www.google-analytics.com, pagead2.googlesyndication.com, directory.cookieyes.com, googleads.g.doubleclick.net, and 5 more
dataLayer events seen
gtm.js, gtm.dom, gatsby-route-change, gtm.load, gtm.click
Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on commonapp.org 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.
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
reviewWrites innerHTML (1)
1 piece of custom code assign to innerHTML.
WhyAssigning innerHTML parses the string as HTML. If any of it comes from the URL, the page or a cookie, that is a script-injection route into your own site.
CheckCheck whether the assigned value is a fixed template or built from something a visitor can influence.
Seenseen in 5.7% 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.
Seenseen in 44.6% of 46,522 containers measured
infoLoads JavaScript from another host (2)
2 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
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
infoVendor IDs written into custom code (1)
1 vendor ID is pasted directly into custom HTML rather than held in a variable or template.
WhyChanging a property, pixel or account then means editing every tag that mentions it, and any one that gets missed keeps sending to the old destination indefinitely.
CheckFine if the ID never changes. If you have ever migrated a property, check that none of these still point at the old one.

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 »
