In this blog, we will explore the benefits of integrating GTM with OneTrust, the step-by-step process of integration, and best practices for managing user consent effectively.

2. Configure Your Preferences: Customize your consent banner, preferences center, and legal notices to align with your brand and compliance requirements.
3. Generate Scripts: Once your preferences are configured, generate the necessary scripts for your consent management platform.

Step 2: Set Up Google Tag Manager

1. Create a GTM Account: If you don't already have one, create a Google Tag Manager account and container for your website.
2. Add GTM to Your Site: Install the GTM container snippet on your website’s header and body tags.

Step 3: Integrate OneTrust with GTM

1. Add OneTrust Script to GTM:some text
   • Go to your GTM account, create a new tag, and select “Custom HTML.”
   • Paste the OneTrust script you generated earlier into the HTML box.
   • Set the trigger to “All Pages” to ensure the script runs on every page load.
2. Configure Data Layer Variables:some text
   • Create data layer variables in GTM to capture consent preferences.
   • Go to “Variables” in GTM and click “New.”
   • Select “Data Layer Variable” and configure it to read the appropriate consent information from the OneTrust script.
3. Set Up Consent Conditions:some text
   • Define triggers in GTM based on user consent preferences.
   • For example, create a trigger that fires only if the user has consented to analytics tracking.

Step 4: Test and Validate

1. Preview and Debug: Use GTM’s preview and debug mode to ensure that the integration is working correctly and that consent preferences are being captured and respected.
2. Conduct Compliance Checks: Verify that your website is compliant with relevant data privacy regulations by testing different consent scenarios.

Best Practices for Managing User Consent

1. Transparency: Clearly communicate what data is being collected and why. Provide detailed information in your privacy policy and consent banner.
2. Granular Consent Options: Allow users to give or withdraw consent for specific types of data processing (e.g., analytics, marketing).
3. Regular Audits: Conduct regular audits of your consent management setup to ensure ongoing compliance and address any issues promptly.
4. User Experience: Design your consent banner and preferences center to be user-friendly and accessible. Avoid dark patterns that pressure users into giving consent.
5. Documentation: Keep detailed records of user consents and any changes to your consent management processes for accountability and legal compliance.
