What the CMP and Cookie Banner Check evaluated
The exam is deliberately fast and focused. It recognizes technical signals in headers, HTML, JavaScript and resources. Interactions with banners, login, forms and tag triggers should be additionally checked in the browser.
A recognized CMP is not yet a tested Consent dialogue

CMP signature recognized → Banner visible? Selection saved? Tags appropriately controlled?The check searches for known CMP signatures and supplementary notes in the document. An integrated CMP script can be detected even though the dialog does not appear in a specific region or the tag control is incomplete.
Then check the results in the browser.
- Go to the website without any saved selections and check the actual visible dialog on desktop and mobile.
- Test Agree, Reject, and Change the Selection Later. Check network and storage together.
- Check whether the selected categories control the intended services and whether the settings are maintained on other page types.
What this check leaves open
Position, usability, text, categories and actual blocking are not tested by a real browser dialog. A self-developed CMP without a known signature can go unrecognized.

A tool shows a concrete symptom. The audit checks up to 500 URLs, prioritizes tracking, consent and form risks, and provides export data.
Targeted deepening of GDPR tracking
Check which cookies a URL technically shows, whether tracking cookie candidates appear and which attributes such as Secure, HttpOnly or SameSite are set.
Before consentRecognize tracking and third-party candidates who are already visible in the initial delivered page before a user actively consents.
Third party third partiesFind well-known tracking services, external script hosts, and third-party integrations that are relevant to consent, privacy, and tag governance.
Google Consent ModeCheck if Google tags have technical consent mode signals visible and if denied/granted hints appear in the code.
Storage & FingerprintingRecognize technical storage and access signals such as cookies, LocalStorage, SessionStorage, IndexedDB and fingerprinting candidates.
Web analysisCheck if a URL contains more frugal analytics candidates or marketing/tracking signals requiring consent.
Questions about CMP and Cookie Banner Check
Does the tool evaluate banner design completely?
No. It recognizes technical and textual signals. Visibility, equivalence and specific UI must also be checked manually.
What is a good sign?
A recognizable CMP, a clear reject option, granular settings and a later revocation are important checkpoints.
Is the individual check free of charge?
Yes. The standalone tools check a single URL. For larger crawls, complete tables and CSV export, the premium audit is planned.
Does the tool replace legal advice?
No. The tools provide technical pre-testing. Legal bases, contracts, information obligations and concrete consent flows must be subject to technical review.
