Why consent rates matter
Low consent = blind data
A trustworthy site achieves ~75% consent rate. If you're at 50%, you're losing 25 percentage points — a quarter of your conversion data, remarketing audiences, and analytics. Waulter helps you reclaim that potential.
Want to see how? →Fines are not theoretical
The Czech data authority (UOOU) actively audits — non-compliance can cost hundreds of thousands of CZK.
Consent is not coincidence
You spend thousands on Google Ads, SEO, and content — then a default cookie popup throws away 25–50 % of your conversion data. That makes no sense.
Check your website
Enter your URL and within seconds discover which cookies your site uses, whether you collect consents correctly, and where your GDPR gaps are.

Good practice in action
Banner variants by traffic source
The scenario engine automatically adapts the banner based on traffic source — campaign traffic gets contextual messaging, blog readers get minimal interruption.
Running Permissions — progressive consent
On the first visit, just analytics. After three articles, personalization. After registration, marketing. Progressive requests increase overall consent by 20–40%.
What valid consent must include
Six conditions simultaneously: freely given, specific, informed, unambiguous, withdrawable, and documented. Waulter meets all six by default.
Permission Transaction
Every consent is a transaction — transaction ID, timestamp, configuration version, page context. Your proof during an audit, not just a claim.
Business activities, not categories
Nobody understands "analytics cookies." Everyone understands "traffic evaluation." Automatic mapping to purpose codes and Google Consent Mode.
Marketing banners and social proof
"92% of visitors trust us." A real number, automatically updated. Add incentives and measure performance with campaign codes.
We don't just cover consents — we cover you
We scan network traffic, check where your data flows, verify cookie banner presence, Google Consent Mode settings, take screenshots, and maintain detailed logs. Complete legal coverage — not just a checkbox.
Where your data flows
We scan network traffic (HAR files) to see which external services and third parties your website communicates with. In simple terms: we check who your site talks to behind the scenes.
External services and scripts
Detection of all third-party scripts, trackers, and services loaded on your pages. Do you know every script running on your site?
Visual verification
We take screenshots of your cookie banner on different devices and browsers. Visual proof that your consent UI looks right and works correctly.
Cookie banner presence
Automatic verification that your consent banner actually displays on every page, not just the homepage.
Google Consent Mode check
We verify your GCM 2.0 signals are correctly configured and firing (default denied → update on consent).
Detailed logging
Every consent interaction is logged with timestamp, config version, user decision, and context. Audit-ready for regulatory inspection.
Together, these checks create complete coverage of legal requirements — a protective shield, not just a checkbox.
Simple, fair pricing
Up to 70% cheaper than international CMPs. No hidden pageview charges.
