Is your tracking actually installed, or just supposed to be?

Paste any URL and we'll check whether Google Tag Manager, GA4, Meta Pixel and Lead Recorder are actually firing from <head>, not just pasted in once and forgotten.

Analytics breaking? Stop finding out from a client

Lead Recorder's one-line script tag guarantees zero lost lead attribution: no separate pixel debugging required.

“It's installed” and “it's working” are different claims

Placement decides what gets missed

A tag added lower in the page, or injected late by another plugin, can miss early page views and above-the-fold clicks: the exact moments a fast-bouncing visitor generates.

Site rebuilds silently drop snippets

A theme change, page builder migration, or a well-meaning "cleanup" of the header often takes tracking scripts out with it. Nothing errors. The data just quietly stops.

Nobody checks until a report looks wrong

Broken tracking doesn't page anyone. It shows up weeks later as an unexplained dip in conversions, once there's no way to recover the lost data.

Script checker, explained

What does this tool actually check?

It fetches the live HTML of the URL you enter (the same way a browser would on first load) and scans it for the script signatures of Google Tag Manager, Google Analytics 4, Meta Pixel, and the Lead Recorder snippet. For each one it reports whether it was found, and whether it's placed in <head> or lower down the page.

Why does it matter whether a script is in <head>?

Google's own Tag Manager documentation recommends placing the container snippet as high in <head> as possible, so it can start listening before anything else on the page loads. A script placed lower, or injected late by another plugin, can miss early events (page views on a fast bounce, clicks on above-the-fold buttons) before it's even registered.

Will this see tags that only load after someone accepts a cookie banner?

No, and that's expected. If your consent management platform correctly blocks tags until a visitor accepts cookies, a plain HTML fetch won't see them either; the tool isn't clicking "accept" on your behalf. That's correct, compliant behaviour, not a false negative on our end.

What about single-page apps that inject tags with JavaScript?

This scans the initial server-rendered HTML, not the fully hydrated, client-side-rendered page. If your site is a React, Vue, or similar SPA that injects tracking tags purely via client-side JavaScript after load, this tool may not see them even though they work fine in a real browser. Treat a "not detected" result on a JS-heavy site as a prompt to double-check manually, not a definite failure.

Do you store the sites I scan?

No. The HTML is fetched, scanned in memory, and discarded; nothing is saved on our servers. The "recent scans" list you see is saved to your own browser's local storage only.

Why did my scan fail or time out?

Some sites block automated requests behind bot protection (Cloudflare, WAFs) or take too long to respond within our request window. A failed scan usually means the site refused or was too slow to answer, not necessarily that anything is wrong with its tracking setup.
