Which pixels really fire on your site — and which ones count twice?

Enter your address. A real browser opens your homepage in mobile view, accepts the cookie banner like a visitor would, and records every ad and analytics request it sends. You get the result on screen, right away.

One address is enough. The email field is optional — fill it in if you would like a short assessment from a human afterwards.

We could not check this address. Please enter a public website, for example your-shop.com.

What the check shows

Six questions, answered from what your site actually sends.

No reading of source code and no guessing from tag-manager containers: we record which requests really go out.

Platforms and IDs

Which platforms receive data and under which ID: Google Analytics 4, Google Ads, Tag Manager, Meta, TikTok, Snapchat, Pinterest, Microsoft, LinkedIn, Reddit and X.

Double counting

Whether a single page view is reported twice — for example two page_view hits for the same property — or whether several accounts of the same platform receive the same visit.

Shop system and consent tool

Which shop system and which cookie banner we recognise. We name the tool; we do not assess your consent setup.

Server-side signals

Whether a server container or your own tracking endpoint is in use. What your shop backend sends from server to server is invisible from outside — we say so in the result.

Click IDs

We open the page with test click IDs (gclid, fbclid, ttclid, msclkid) and check whether they survive your redirects and get stored. A lost click ID means a paid click that later counts as direct.

Blockable scripts

Which tracking scripts load from third-party domains. Ad blockers and browsers with tracking protection typically block exactly these — visitors using them are missing from those platforms’ numbers.

What it cannot see

One page from outside is not the whole picture.

The check looks at your homepage the way a visitor sees it. That is a quick, honest snapshot — and it has limits we would rather name than hide.

Checkout and purchases

Whether purchases are reported correctly happens in the checkout and in your shop backend. We do not place test orders.

Server-to-server sending

Conversion APIs that your shop or an app sends directly from a server leave no trace in the browser.

Data quality in your accounts

Whether your ad accounts claim more purchases than your shop had only shows when both sides are compared — that is what the 30-day parallel run is for.

Your ad accounts stay clean. During the check we stop requests to known ad and analytics endpoints before they leave the browser, so no platform records a test visit or a test click ID. A custom tracking endpoint on your own domain may still count one page view.
FAQ
Why is this free?
Because the check runs automatically and shows what we look at first in every new project. If the result raises questions, we are happy to talk — but you do not have to.
Does the check change anything on my site or in my accounts?
No. It is one visit with a normal browser. Requests to the platforms are stopped before they are sent, so your ad accounts do not see a test visit.
Is the cookie banner accepted?
Yes, where we recognise it — like a visitor who clicks “accept”. Only then do many pixels load at all. We do not assess whether your consent setup is legally correct.
Can I check any website?
Any public website. The check sees nothing that an ordinary visitor could not see. Internal addresses and IP addresses are rejected.
How long is the result stored?
The result page stays available for 90 days under a link that cannot be guessed, then it is deleted. An email address, if you entered one, is only used to send you the assessment.

The check shows the surface. The parallel run shows the numbers.

Whether your ad accounts claim purchases your shop never had only shows once both sides are measured. 30 days in parallel, €0, alongside your current setup — then from €299/month, cancel monthly.
