Check your tracking
Paste a URL. We fetch the page like a normal visitor and tell you what is actually in it — which pixels, which IDs, and whether any of them is set up twice.
Tip: your site may hide tracking from admins — this check sees what a real visitor sees. If you are logged in to your own store, open it in a private window to compare.
What it looks at
-
Which pixels are on the page
Meta, GA4, Google Ads, Google Tag Manager, TikTok, Microsoft UET, Pinterest and Snapchat — with the account IDs we can read.
-
Whether any of them is installed twice
The same account ID initialised in two places is the most common cause of double-counted conversions. A loader plus one config call is a normal single install and is not flagged.
-
What your consent setup looks like
Whether a Consent Mode default block is present, what it defaults to, and whether a consent tool we recognise is on the page.
-
Cache headers, HTTPS, size and speed
Page caching is where baked-in event IDs go wrong, so we show the cache headers your server returned.
And what it honestly cannot
Server-side sending cannot be confirmed from outside — only your plugin's own logs can prove it. This check also does not execute JavaScript, so tags injected only by JS after load may not appear, and anything inside a Google Tag Manager container is invisible to it. Every report says so, in the report.
questions
About this tool
Does this change anything on my site?
No. The checker requests your page the same way a visitor’s browser does and reads what comes back. Nothing is installed, nothing is submitted, and no login is involved.
What do you store?
The URL you submitted, the time of the check, the score and the detections — kept for 30 days so the report link keeps working, then deleted. We do not store your IP address or a copy of your page.
Why does it say it cannot confirm server-side tracking?
Because it cannot. A Conversions API event goes from your server to the platform and never touches the HTML a visitor receives. Any tool claiming to verify that from the outside is guessing. Only your own plugin logs can prove it.
My tags are added by JavaScript. Will they show up?
Possibly not. This version reads the HTML your server sends and does not execute JavaScript, so tags injected only by JS after load may not appear. A rendering version is planned.
Is there a limit?
Yes — a small number of checks per hour per visitor, so the tool stays free and fast for everyone. If you hit it, the page says so plainly.
A page check is the start. Proof is the product.
The checker tells you what is on the page. PixelCapi tells you what actually arrived at the platform, event by event.
