Google Consent Mode v2 Validation

Last updated: February 18, 2026
Use this page to verify Google Consent Mode v2 implementation quality before release.

1. Required Consent Signals#

Verify all four keys are set and updated:
ad_storage
analytics_storage
ad_user_data
ad_personalization

2. Required Ordering#

Baseline expectation:
1.
Consent default is set before Google tags evaluate.
2.
User choice triggers consent update.
3.
No conflicting consent commands are pushed by other scripts.
For GTM, use Consent Initialization - All Pages trigger.

3. Browser Console Checks#

Expected result: you can see both default and update commands in order.

4. Tag Assistant Checklist#

1.
Open Tag Assistant preview.
2.
Reload a page with fresh session.
3.
Confirm consent defaults are present before Ads/Analytics tag execution.
4.
Interact with banner.
5.
Confirm consent update values change according to choice.

5. GTM Best Practices#

Keep CMP tag in Consent Initialization, not regular Page View.
Avoid duplicate consent default commands from multiple templates.
Keep region overrides documented in container notes.

6. Common Failures#

Consent defaults pushed too late.
Tags fire before consent defaults.
Missing one or more v2 keys in default or update calls.
Another plugin overwrites consent state.

7. Evidence to Store for Audits#

Tag Assistant screenshots with event timeline.
Browser console export of consent events.
CMP debug report from production domain.
