Nesoulad Google Consent Mode

Proč je to důležité

Pokud Consent Mode signalizuje denied, ale Analytics nebo Ads requesty se stejně načítají, web jen vytváří falešný dojem souladu. Obvykle jsou nekonzistentně nastavené defaulty, tagy nebo runtime aktualizace.

Jak to ověřit ručně

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 příčiny

• 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 ve WordPressu nebo CMP pluginech

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.

Obecná vývojářská oprava

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.

Jak potvrdit, 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.
