Google Consent Mode mismatch

Fix cases where Google tags behave as if consent is granted even though runtime consent state says denied.

Zahŕňa: consent_mode_mismatch, consent_mode_default_granted, consent_mode_runtime_conflict

Prečo je to dôležité

If Google Consent Mode signals denied consent while analytics or ad requests still load, the site creates a false appearance of compliance. This usually means tags, defaults, or runtime updates are configured inconsistently.

Ako to overiť manuálne

  1. Open the site in a fresh session and inspect Google requests before any banner interaction.
  2. Check whether Consent Mode defaults are set to denied before Google tags initialize.
  3. Compare runtime consent state against actual network behavior after Accept and Reject.

Typické príčiny

  • Consent defaults are set too late, after Google tags already loaded.
  • GTM tags ignore consent checks even though Consent Mode is enabled.
  • Banner updates UI state but does not send a matching consent update to Google.

Oprava v GTM

  1. Use Consent Initialization for your default denied state before any analytics or ads tags run.
  2. Require consent checks on GA4, Google Ads, Floodlight, and remarketing tags.
  3. Audit custom HTML tags that may load Google scripts outside GTM consent controls.

Oprava vo WordPress alebo CMP pluginoch

  1. Enable Consent Mode integration in your CMP plugin if available.
  2. Verify that plugin-generated consent events fire before GA4 or Ads plugins load.
  3. Disable duplicate analytics plugins that bypass the CMP integration.

Všeobecná oprava pre vývojára

  1. Initialize Google tags only after a denied-by-default consent state is established.
  2. Send explicit consent updates on accept and reject actions.
  3. Ensure fallback defaults are denied whenever consent state is unknown.

Ako potvrdiť, že oprava funguje

  • Reject optional consent and confirm that Google analytics or ads requests do not fire.
  • Accept consent and confirm requests start only after the consent update.
  • Run a fresh scan and verify the mismatch finding disappears.

Ďalší krok

Po deployi spustite nový sken a potvrďte, že sa zmenilo reálne runtime správanie, nielen text banneru.
