Implementing Consent Mode with Cookiebot, Google Tag Manager, and Webflow: A Marketer’s Guide

Introduction

Data privacy is no longer optional for businesses—it’s a core responsibility. As marketers, our challenge is to glean insights from website analytics while respecting user consent and adhering to regulations like GDPR and CCPA. Striking this delicate balance can seem daunting. After all, how do you maintain accurate data collection when your marketing objectives hinge on measuring conversions, tracking user behavior, and optimizing campaigns?

Enter consent mode, a powerful feature that enables you to honor user preferences without sacrificing all your analytic capabilities. Combined with tools like Cookiebot, Google Tag Manager, and Webflow, you can deploy a robust, privacy-first structure that satisfies both legal standards and marketing objectives. In this post, we’ll break down the basics of consent mode, walk through practical steps for implementing it, and showcase how these integrations can help keep your analytics healthy while staying compliant.

Let’s dive in!

Why Consent Mode Matters for Website Analytics

The Evolving Privacy Landscape

In an era where data breaches make headlines almost daily, privacy regulations have evolved to put more control in the hands of users. As a result, simply dropping cookies the moment a visitor lands on your site is no longer acceptable. This shift has led to the rise of consent management platforms and frameworks designed to clarify data collection practices.

From a CMO or VP of Marketing standpoint, compliance isn’t just a legal obligation—it’s also a critical component of brand trust. Demonstrating respect for user data can positively influence customer perception and loyalty, all while aligning your organization with current and upcoming data protection regulations.

Consent Mode in a Nutshell

Consent mode (particularly from Google) allows you to adjust how certain tags behave based on user consent. If a user opts out of tracking, your tags limit the volume or type of data they capture (for instance, anonymizing IP addresses). Conversely, if the user grants consent, the tags can function as usual, enabling full-scale analytics.

The key value proposition here is the ability to continue collecting aggregated or non-identifying data for website analytics, even when users don’t grant full permissions. This ensures your marketing decisions remain data-driven while respecting individual choices.

Balancing Compliance and Insights

  • Regulatory Compliance: GDPR, ePrivacy, and other policies demand explicit consent for personal data collection. Failure to comply can result in hefty fines.
  • Maintaining Accuracy: Without a consent layer, you either risk non-compliance or lose vital insights. Consent mode ensures you maintain a degree of measurement integrity.
  • User Trust: Transparent data practices help build trust and long-term relationships with customers, a crucial element in brand reputation.

Getting to Know Cookiebot

What Is Cookiebot?

Cookiebot is a leading consent management platform (CMP) that helps website owners manage cookies and tracking scripts in line with data protection regulations. By automatically scanning your site, it identifies cookies, classifies them, and provides a neat interface for users to manage their preferences.

Core Features and Benefits

  1. Automated Cookie Scanning: Cookieb
  2. Cookiebot periodically scans your site to detect new cookies, ensuring your cookie declaration remains up to date.
  3. Granular User Control: Offers an intuitive widget that allows visitors to choose which cookie categories to enable or disable.
  4. Easy Integration: Works seamlessly with major content management systems and web builders like Webflow.
  5. Dynamic Cookie Blocking: When a user opts out, Cookiebot automatically blocks tracking scripts, helping you comply with legal requirements without manual intervention.

Why Cookiebot Matters for Marketers

For busy marketing teams, the ease of integrating Cookiebot can be a game-changer. Rather than juggling complex code, you can rely on Cookiebot’s automation to keep you compliant. Plus, it helps ensure your consent mode setup works properly across various platforms, from Google Tag Manager to your Webflow site.

Setting Up Consent Mode with Google Tag Manager

Why Use Google Tag Manager?

Google Tag Manager (GTM) is a versatile tool that simplifies the deployment of marketing tags and code snippets. By centralizing all your tracking scripts in GTM, you can manage them from a single dashboard—no more editing individual pages or dealing with messy code. For marketers, it also streamlines collaboration and reduces reliance on developers for minor updates.

Preparing GTM for Consent Mode

  1. Create a Tag Setup: Start by creating or identifying your Google Analytics tag within GTM. Ensure it’s configured to handle analytics data in accordance with consent mode.
  2. Enable Consent Mode: In GTM, you can enable consent checks and choose how tags should behave under different consent statuses (granted or denied).
  3. Use Triggers: Utilize triggers that fire only when a user has given explicit consent. This ensures your marketing tags respect the user’s preferences.

Integrating with Cookiebot

Cookiebot can send consent states back to GTM. Here’s how:

  1. Implement Cookiebot Scripts: Place the Cookiebot scripts on your site (or inject them through GTM).
  2. Set Up Consent Variables: In GTM, create variables that capture consent states from Cookiebot.
  3. Create or Modify Tag Firing Rules: Adjust your GTM tag firing settings to reference these consent variables. If a user chooses to allow only minimal tracking, limit the tags that fire. If they permit full tracking, enable your entire set of marketing and analytics tags.

Bringing It All Together in Webflow

Why Webflow?

Webflow is a popular website builder that offers a blend of design flexibility and intuitive user experience. Its visual interface empowers marketers to rapidly prototype, design, and publish web pages without extensive coding. When combined with Cookiebot and GTM, you have a full-stack solution for capturing analytics in a compliant manner.

Injecting Scripts into Webflow

Here’s a general approach to installing Cookiebot, GTM, and consent mode in your Webflow project:

  1. Global Project Settings: In Webflow, navigate to your project settings and go to the “Custom Code” tab. Here, you can add scripts in the <head> or </body> sections site-wide.
  2. Add Cookiebot: Paste your Cookiebot script in the <head> custom code box. This ensures Cookiebot loads early and can block or enable scripts based on user preferences.
  3. Add Google Tag Manager: Next, copy the GTM container snippet into the <head> or </body> section, depending on Google’s latest recommendations.
  4. Sync Consent States: By default, your GTM container might load immediately. Make sure you set up triggers that reference Cookiebot’s consent status.

Practical Tips and Best Practices

  • Minimalist Approach: Don’t bloat your site with too many tags. Each script can slow page loading and complicate compliance.
  • Regular Audits: Periodically scan your Webflow site with Cookiebot to identify any new cookies or scripts that may have been added without your knowledge.
  • Test in Staging: Before going live, test your setup in a staging environment. Check if your GTM tags fire only when they should, and confirm the Cookiebot banner functions properly on both desktop and mobile.
  • Optimize Performance: Consider implementing asynchronous or deferred loading for non-critical scripts. This ensures your site remains fast and user-friendly.

Activate GTM’s Consent Mode (Optional but Recommended)

Consent Mode in GTM allows you to dynamically control how tags behave based on user consent. By enabling it, you ensure that non-essential tags (like analytics or ads) won’t load until the user agrees.

Access Container Settings

  • In your GTM workspace, click on Admin in the left sidebar
  • Under the Container column, select Container Settings

Enable Consent Mode

  • Check the box for Enable Consent Mode (sometimes labeled Consent Overview)
  • Set default consent states, such as analytics_storage and ad_storage, to denied by default.

Future Updates

  • As users interact with the Cookiebot consent banner, you can dynamically update these consent states in GTM.
