Cookiebot Tutorial – Add a Cookie Banner and Configure Consent Mode V2 with GTM

Why It Matters

Implementing Cookiebot with GTM ensures GDPR‑compliant data collection while preserving analytics accuracy, protecting businesses from regulatory risk and building user trust.

Key Takeaways

• Add Cookiebot via GTM to manage consent across platforms.
• Enable Consent Overview in GTM to monitor tag consent status.
• Configure built‑in consent tags and custom triggers for third‑party tags.
• Test consent flow using GTM preview and verify G‑state values.
• Publish changes and continuously audit new tags for consent compliance.

Summary

The video walks viewers through installing Cookiebot—a consent‑management platform—using Google Tag Manager (GTM) and wiring it to Google Consent Mode v2. Benjamin demonstrates creating a Cookiebot account, adding a domain, customizing the banner’s layout, design, and geographic targeting, then copying the domain‑group ID for GTM integration. He also highlights User Centrics’ server‑side tagging and privacy‑policy generator as complementary tools.

Key steps include enabling the Consent Overview in GTM’s container settings, adding a Cookiebot tag from the community template gallery, and ensuring the tag fires on the Consent Initialization trigger so it loads before any other tags. Built‑in consent tags (Google Analytics, Google Ads) automatically respect consent, while third‑party tags such as LinkedIn Insight or Meta Pixel require manual consent settings and a custom "cookie_consent_update" trigger. The tutorial shows how to set default consent states, adjust geographic defaults, and configure required consent types (storage, personalization, user data).

Benjamin verifies the setup using GTM’s Preview mode: before consent, Google tags fire in advanced consent mode with a G 100 state, while the LinkedIn tag remains dormant. After clicking "Allow all," the state switches to G 111, cookies are stored, and the LinkedIn tag fires—demonstrating proper consent handling. He also notes that the default is to deny consent until a user makes a choice, aligning with GDPR best practices.

The walkthrough underscores that compliant consent management is now a prerequisite for any site collecting analytics or advertising data. By integrating Cookiebot with GTM, marketers can automate consent signaling, avoid legal exposure, and maintain data integrity across first‑ and third‑party tags. Ongoing vigilance is required: every new tag must be reviewed in the Consent Overview to ensure it respects user choices, preserving both regulatory compliance and user trust.
