Ads measure and target worse
Without Consent Mode v2, Google gets no consent signal. For visitors from the EU it then limits remarketing and audiences in Google Ads.
Cookie banner and Consent Mode v2 for online shops
Does your shop set advertising cookies before the customer agrees?
In many smaller online shops we have checked, Meta Pixel or Google Ads fires before the visitor clicks the cookie banner. We check it for free, send the proof and fix it for a fixed price.
We check only the public part of the site, like any visitor. Nothing to install, no access needed.

Why it matters
A wrong consent setup costs advertising data and customer trust.
The banner promises a choice the site does not keep
The visitor clicks “Reject” and tracking keeps running. Anyone can verify that in a browser in a few minutes.
Consent rules
A site may set advertising and analytics cookies only after the visitor consents. The ePrivacy Directive requires this in every EU country.
What the check covers
We load each site several times in a browser with no stored cookies, on desktop and mobile. A finding counts only when it repeats.
01Cookies and consent
Which advertising and analytics tools run before consent or after reject, and whether “Reject” is as visible as “Accept”.
02SEO and speed
Titles, descriptions, structured data, sitemap, mobile load speed (LCP, CLS).
03Accessibility
Problems against WCAG 2.1 AA. The European Accessibility Act has applied to online shops since June 2025.
04Product data
Price, availability, brand and GTIN in product structured data for Google and comparison sites.
05E-mail and security
SPF and DMARC (so your e-mails stay out of spam), SSL certificate and security headers.
06Marketing and automation
Newsletter, reviews, chat and conversion tracking. Where an AI chatbot or automatic product descriptions make sense.
How it works
No meetings and no long contracts.

Frequently asked questions
Why is the check free?
The measurement is mostly automatic, so it costs us little time. Some shops then order the fix from us. The report is yours even if you order nothing.
What does the fix cost and when do I pay?
The cookie fix costs €59 excl. VAT, one-off. We invoice only after we verify the fix works, with 14 days to pay. If we cannot verify the fix, you pay nothing.
What is Consent Mode v2?
The way a site tells Google tools whether the visitor agreed to measurement and advertising. Since March 2024 Google requires it for remarketing and personalised ads for visitors from the EU.
Will measured conversions drop after the fix?
Usually yes. Visitors who reject cookies are no longer measured. Google can estimate part of the conversions by modelling. This is the expected result, not a fault.
Do you need access to the shop admin?
Not for the check. For the fix, yes: we ask for a separate account with the lowest rights needed, never for your password.
How long does the fix take?
On a common platform usually one to three working days after we get access.
Which platforms do you work with?
Shopify, WooCommerce, PrestaShop, Shoptet and Upgates. For another platform we tell you after the check whether we can do the fix.
Which countries and languages?
Online shops anywhere in the EU. We communicate and write reports in English, Czech or Slovak.
What if we fix it ourselves?
That is fine. You can pass the report to your web administrator. After the fix we check the site again for free on request.
Is this a legal opinion?
No. The report is a technical observation: what runs on the site and when. For legal questions we recommend a lawyer.
