Tagging Health Check is an auditing tool for Google Analytics 4 (GA4), Google Tag Manager (GTM), and Adobe Experience Platform Launch (Adobe Launch). You connect it to your own Google account, and it runs a structured set of automated checks against the GA4 properties and GTM containers you have access to, covering things like tracking setup, data quality, tag health, PII exposure, bot traffic, ecommerce parameter coverage, and consent configuration.
You can audit a single property, or run a bulk audit across every property in a GA4 account. A bulk audit works through those properties one at a time, in sequence, not all at once, to stay within Google's API rate limits. You can also pull month by month event counts across an entire account, and export any audit's results to Google Sheets, Excel, or a Google Slides deck, on request.
When you sign in with Google, this app requests permission to read the following, limited to your own Google account:
Access to Google Analytics is read only. This app never creates, modifies, or deletes anything in your GA4 property.
We never request access to Gmail, Contacts, Calendar, or anything outside the scopes above.
Each time you run an audit, results are pulled fresh from Google's APIs and shown in your browser. If you come back to a property you've already audited, the app will show you that same result from your browser's local storage rather than pulling it again right away, similar to how GA4's own reporting can show a cached view. You'll see a "Cached X ago" label whenever you're looking at a result like this.
That cached copy expires automatically after 2 hours. After that, or any time you explicitly run a new audit, you get fresh data pulled directly from Google.
In your browser: cached audit results are stored only in your own browser's local storage and expire automatically after 2 hours. If you're on the free tier, rather than a paying customer or an admin, your results and this cache are also cleared automatically 5 minutes after an audit finishes, whichever comes first, so nothing lingers in your browser after a quick evaluation.
On our servers: audit data is processed temporarily on our servers only to generate the exports you request (Google Sheets, Excel, Google Slides), or, if you explicitly use the "Share" feature, to serve a read only link. Shared links stop working automatically 8 hours after they're created. We don't use this data for anything beyond fulfilling the specific action you requested.
We use Google Analytics 4 (GA4), delivered through Google Tag Manager, to understand how visitors use scarlette-tadhg.com. This is separate from the GA4 properties this app audits on your behalf when you connect your own Google account, described above.
Once you've consented via the cookie banner, Google Analytics collects standard web analytics about your visit: which pages you view, how you arrived here (referrer or traffic source), how long you spend on the site and how you interact with it, your approximate location (city or country level, derived from your IP address, not your exact address), and general device, browser, and operating system information. We don't use Google Analytics to identify you personally, and this GA4 property isn't linked to Google Ads or any advertising product.
This site uses Google's Consent Mode. Before you respond to the cookie banner, Google Analytics may still receive a limited, cookieless signal, no _ga cookie, no ability to track you across visits, that Google uses only for aggregate, modeled traffic estimates. Full analytics tracking, including the _ga cookie, only starts once you accept analytics cookies in the banner.
You can see or change your consent choice at any time via the "Cookie Settings" link in the site header, or review Google's own privacy practices at policies.google.com/privacy.
Necessary: when you connect your Google account, a small set of sign-in cookies are set to keep you signed in and protect the sign-in process itself (a session cookie, plus short-lived security cookies used only during the sign-in step). These exist only for that purpose, they are not used for tracking, advertising, or analytics, and they are not gated behind cookie consent since they are strictly necessary for the app to function.
Analytics: Google Analytics sets an analytics cookie (e.g. _ga) once you consent via the banner below. See "Analytics on this site" above for what data this collects. We also use Vercel Web Analytics and Vercel Speed Insights, our hosting provider's own tools, for traffic and performance monitoring; both are cookieless by design and don't require consent.
We also use your browser's local storage (a different, non-cookie mechanism) for a few things already described above: remembering your light/dark theme choice, briefly caching your credit balance, and caching recent audit results.
When you sign in with Google or pay through Stripe, that happens on Google's or Stripe's own site, and any cookies set during those steps are set by them, under their own privacy policies, not by us.
This site uses CookieYes, a cookie consent management platform, to show a consent banner and let you accept, reject, or customize cookie categories, including the analytics cookies described above. CookieYes sets its own cookie to remember your preference so you're not asked again on every visit.
No. We don't sell your data, use it for advertising, or share it with any third party. Files you choose to export land in your own Google Drive, not ours.
You can revoke this app's access at any time from your Google Account's third party access settings. Doing so immediately stops the app from accessing your data.
