Free Website Tracking Checker: GTM, GA4, Google Ads & Meta Pixel
Enter a website to see which tracking tags it loads, and spot duplicate tags, missing consent and server-side setups in seconds.
Scans the page and its GTM containers for 26 analytics and ad platforms, duplicate tags, lead and purchase events, consent and server-side tracking. Free, no signup, nothing stored.
What the checker looks for
It reads the page you enter, downloads every Google Tag Manager container on it (including containers loaded through a Stape custom loader) and looks for GA4 and Google Ads IDs, the Meta Pixel, TikTok, Microsoft Clarity and UET, LinkedIn, Pinterest, Snapchat and Hotjar, both in the page and inside GTM. It reads Shopify app pixels too. It flags two GTM containers, the same GA4 or Meta Pixel loaded twice, old Universal Analytics code, a missing cookie banner, and shows when events are sent to a server-side container.
What it cannot see
It shows which tags are installed, not whether each event fires at the right moment with the right value. Shopify custom pixels, Conversions API events sent from your server and conversion values need a look inside your accounts, which is what the free audit covers. Sites with bot protection may block the scan.
Frequently asked questions
Is the Tracking Checker free?
Yes. It is free, has no signup and does not store the addresses you check.
Does it find tags inside Google Tag Manager?
Yes. The checker downloads each GTM container on the page and lists the GA4, Google Ads, Meta, TikTok and other tags configured inside it, marked as "inside GTM".
What does a custom GTM loader mean?
It means GTM is loaded from your own domain instead of googletagmanager.com. This is usually a server-side tracking setup, for example with Stape, which helps tags avoid ad blockers.
The checker could not open my site. Why?
Some sites block automated requests or take too long to answer. Send me the link on WhatsApp and I will check it by hand.
