Enter your website and we will check it live for a Google Tag Manager container, GA4, and a Consent Mode signal - the same kind of public evidence we use to catch real issues.
What We Check
This tool reads your site's public page code the moment you submit it. Here is exactly what it looks for.
Whether a GTM container is present on the page, and which domain it loads from.
Whether a GA4 measurement ID is configured on the page.
Whether a gtag consent default call runs before scripts fire - the exact type of check that caught a real compliance gap on a live client site.
Whether a recognised cookie-consent platform is running on the page.
Whether Meta, Google Ads, LinkedIn, TikTok, or Pinterest pixels are present, and whether they appear alongside a consent signal.
Worth Knowing
This tool only reads your site's public page source - it does not run a real browser, so it cannot see cookie behaviour, actual ad-blocker impact, or how tags fire once a visitor makes a consent choice. Those require the kind of hands-on review we do manually. We built it this way on purpose: a fake instant score would look impressive but would not be accurate, and accuracy is the entire point of TagNexus.
