Introduction
Migrate from Cookiebot to GDPRChecker without double banners, conflicting consent storage, or an unverified gap in pre-consent enforcement.
What it means
Do not run two consent runtimes indefinitely. Double banners and competing consent storage can create inconsistent visitor choices and unreliable tracker behaviour.
Inventory Cookiebot configuration, categories, declarations, GTM triggers, and custom markup before changing production scripts.
Install and verify GDPRChecker first, publish the matching banner and Consent Mode settings, then test in staging or a controlled production window.
Only remove the Cookiebot script after GDPRChecker verifies initial, reject, analytics-only, accept, navigation, and withdrawal behaviour on the live site.
Why it matters
A CMP migration is an enforcement change, not a visual redesign. The riskiest period is the transition where old and new scripts compete or neither blocks a tag.
Common mistakes
- Treating a copied snippet as installed without verifying a live runtime heartbeat.
- Placing the consent runtime after GTM, analytics, advertising pixels, or theme-injected scripts.
- Publishing a configuration change without testing a clean browser session and the Reject all path.
- Applying a broad blocking rule without reviewing the detected provider and category first.
Practical checklist
- Confirm domain ownership and open the site-specific Privacy Setup flow.
- Install or update the GDPRChecker runtime before non-essential tracking code.
- Publish the banner configuration and verify its live heartbeat.
- Test initial visit, Reject all, analytics-only, Accept all, and withdrawal in a private window.
- Run a compliance scan and keep the resulting evidence with the release record.
- Enable scheduled scans so later tag, plugin, theme, or campaign changes are detected.
How GDPRChecker helps
GDPRChecker provides a guided install path, runtime verification, Consent Mode v2 report, Scheduled Scans, and Evidence Center so the migration has a documented baseline and outcome.
Use the first GDPRChecker scan before removing Cookiebot and a second scan after removal to document the verified transition.
