Does your site track visitors before they consent?
This free cookie banner checker fetches your site like a first-time visitor — before any consent — and grades what it finds: pre-consent tracking pixels, tracking cookies on first load, your CMP, Google Consent Mode v2 and policy links, graded A–F with concrete fixes.
We read your public HTML and response headers, pre-consent. Nothing is stored. Not legal advice.
Your consent-compliance report will appear here — grade A–F, what fires before consent, and the exact fixes.
What is a cookie banner checker?
A cookie banner checker tests the part of consent compliance that's invisible to the eye: what your site actually does before anyone clicks a banner. Most sites look compliant — there's a banner, there are buttons — while tracking pixels quietly fire and tracking cookies land on the very first page load, before any choice was made. That's precisely the pattern European regulators look for first.
This free tool fetches your page the way a first-time visitor's browser receives it — server HTML and headers, before any JavaScript consent is given — and grades five things with the exact fixes. It's the same first check we run in a full compliance-and-tracking audit.
The five things it checks
- Consent management — is a CMP (Cookiebot, OneTrust, Usercentrics…) or a consent banner present at all?
- Pre-consent firing — are Meta Pixel, GA4, TikTok, LinkedIn and other trackers hard-coded to load before consent?
- Tracking cookies on first response — does your server set
_ga,_fbpor friends before anyone consents? - Google Consent Mode v2 — are denied-by-default consent signals in place before Google tags load?
- Policies & disclosure — are a privacy policy and cookie policy linked?
Enforcement is real: the Dutch regulator (AP) runs large-scale cookie-banner inspections with a structural budget, and fines misleading banners. We wrote up how to fix ad tracking under GDPR — and for Dutch readers, how to stay AP-proof without losing your conversion data.
One connected workflow
Consent is where lawful measurement starts — but it's one part of a connected toolkit. Get compliant, then make sure every click that follows is tracked end-to-end.
Frequently asked questions
What does this cookie banner checker test?
It fetches your page exactly like a first-time visitor before any consent is given, and grades five things: whether a consent management platform (CMP) or banner is present, whether tracking scripts are hard-coded to fire before consent, whether your server sets tracking cookies on the very first response, whether Google Consent Mode v2 defaults are in place, and whether privacy and cookie policies are linked.
Why does firing pixels before consent matter?
Under the GDPR and the ePrivacy rules, marketing pixels and tracking cookies need consent before they run. European regulators actively enforce this — the Dutch AP, for example, runs large-scale cookie banner inspections and fines misleading or non-compliant setups. Pre-consent tracking is the pattern they look for first.
Can this tool see my banner's buttons?
Only if the banner is rendered in your server HTML. Most CMPs (Cookiebot, OneTrust, Usercentrics and others) inject the banner at runtime with JavaScript, so its buttons aren't visible to a server-side checker. In that case the tool tells you exactly what to verify manually: the first layer must offer "Reject all" as prominently as "Accept all".
Is a passing grade the same as being legally compliant?
No. This tool flags the technical patterns regulators look at — pre-consent firing, tracking cookies on first load, missing consent tooling. It's a fast, honest snapshot, not legal advice. A full compliance review also needs a real-browser audit and a legal read of your policies.
Is it free and is anything stored?
It's completely free with no sign-up, and nothing is stored — each check runs in real time and results aren't saved. Leaving your email is optional and only used to follow up with fixes.
What is Google Consent Mode v2?
Consent Mode v2 is Google's mechanism for making tags respect the visitor's choice. With defaults set to "denied" before any Google tag loads, Google tags send only anonymous, cookieless pings until consent is granted — and Google can model the conversions you legally can't observe. Since 2024 it's required for remarketing and ad personalisation in the EEA.
