Conversion tag checker

See which GA4, Google Ads, Tag Manager and Meta tags are on a page, and catch the duplicates that double your conversions.

Enter an address and run the check. Results show here in a few seconds.

Assumptions and limits

We read the HTML the server sends. Tags fired from inside Google Tag Manager, a consent tool or a plugin that injects them later won't show here.
Duplicates are counted from the snippets in the HTML. A tag that fires twice inside GTM needs GTM Preview mode to spot.
We fetch the page once, as an anonymous visitor with no cookies, from Cloudflare's network.
No JavaScript is executed. Anything a script adds after the page loads is invisible to this check.
It is one sample, taken now. Pages that vary by location, device or time can answer differently for someone else.
Each fetch waits up to 10 seconds, follows up to 10 redirects and reads up to 1 MB.
We don't store the address you check or the result. You can run 30 checks every 10 minutes.

What it checks

GA4 measurement IDs

Every G- ID in the HTML, and how many times each is loaded or configured.
Google Ads tags

AW- conversion IDs and any conversion labels on the page.
Tag Manager and Meta

GTM containers and Meta pixel IDs, plus retired Universal Analytics code.

Clean data in

Double counted or missing conversions teach Google Ads the wrong lesson. We audit and fix tracking before we spend a dollar.
