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
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.
A wrong consent setup costs advertising data and customer trust.
Without Consent Mode v2, Google gets no consent signal. For visitors from the EU it then limits remarketing and audiences in Google Ads.
The visitor clicks “Reject” and tracking keeps running. Anyone can verify that in a browser in a few minutes.
A site may set advertising and analytics cookies only after the visitor consents. The ePrivacy Directive requires this in every EU country.
We load each site several times in a browser with no stored cookies, on desktop and mobile. A finding counts only when it repeats.
Which advertising and analytics tools run before consent or after reject, and whether “Reject” is as visible as “Accept”.
Titles, descriptions, structured data, sitemap, mobile load speed (LCP, CLS).
Problems against WCAG 2.1 AA. The European Accessibility Act has applied to online shops since June 2025.
Price, availability, brand and GTIN in product structured data for Google and comparison sites.
SPF and DMARC (so your e-mails stay out of spam), SSL certificate and security headers.
Newsletter, reviews, chat and conversion tracking. Where an AI chatbot or automatic product descriptions make sense.
No meetings and no long contracts.
Send us the shop address. In two working days you get a report with findings and screenshots.
We set up the cookie banner, Consent Mode v2 and tag firing in GTM.
After the fix we check the site again and send a before and after comparison. Only then do we invoice.
We check the site every week and tell you when a new plugin or campaign breaks the setup.

Lyneon is run by Matúš Maruščák. We verify every finding with repeated measurement, and a person reviews each report before it goes out. He answers your message himself.
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.
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.
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.
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.
Not for the check. For the fix, yes: we ask for a separate account with the lowest rights needed, never for your password.
On a common platform usually one to three working days after we get access.
Shopify, WooCommerce, PrestaShop, Shoptet and Upgates. For another platform we tell you after the check whether we can do the fix.
Online shops anywhere in the EU. We communicate and write reports in English, Czech or Slovak.
That is fine. You can pass the report to your web administrator. After the fix we check the site again for free on request.
No. The report is a technical observation: what runs on the site and when. For legal questions we recommend a lawyer.
