Cookie and cookie consent banners have become essential for websites to comply with global data protection laws like GDPR, CCPA, etc. Consent banners help inform users about data collection practices and provide them with the option to accept or reject the use of cookies.

This guide will walk you through the importance of consent banners, how to implement them using Google Tag Manager, and real-world benefits of using these tools in your digital strategy.

Latest Facts & Trends in Consent Management

Let’s take a quick look at some current trends in consent management that emphasize the growing importance of this topic:

• GDPR fines totaled over €1.5 billion in 2023, with non-compliant websites being a major target.
• 75% of users are now aware of how their data is being collected and prefer websites with clear consent banners.

What is a Consent Banner and Why Is It Important?

A consent banner is a notification or pop-up that informs users about the data being collected via cookies on a website. Consent banners are essential to comply with privacy regulations such as the GDPR (General Data Protection Regulation) in Europe, and CCPA (California Consumer Privacy Act) in the U.S. These regulations require that users provide explicit consent before certain types of cookies, especially third-party cookies, are activated.

Key Features of an Effective Consent Banner

• Customizable Messaging: Tailor the message to explain your data collection clearly, while aligning with your brand’s tone.
• User-Friendly Design: The banner should be easy to understand, with clear buttons for accepting or rejecting cookies.
• Granular Control: Users should have the ability to manage which cookies they want to enable (necessary, analytics, or marketing).

8 Companies That Faced Cookie Consent Fines

TikTok – $5.4 million

In January 2023, TikTok was fined $5.4 million by France’s data protection authority (CNIL). They made it hard for users to reject cookies by requiring more clicks than accepting them. TikTok fixed this by adding a “Refuse All” button. They were also fined for not clearly explaining the purpose of the cookies. TikTok says they’ve now made changes to improve user privacy.

Microsoft – $65 million

In December 2022, Microsoft was fined $65 million because bing.com didn’t make it easy to refuse cookies. French users had cookies placed for advertising without their consent. Microsoft was ordered to get user permission before setting these cookies. If they didn’t comply, they would face a daily fine of €60,000.

Sephora – $1.2 million

In August 2022, Sephora became the first company fined under California’s Consumer Privacy Act (CCPA).

Google – $162 million

At the end of 2021, Google was fined $162 million by CNIL for making it easier to accept cookies than to refuse them on google.fr and YouTube. Google had to fix this issue or face further penalties. They complied by adding an “Only allow essential cookies” button next to the accept button by the given deadline.

Facebook – $65 million

Facebook was fined $65 million for a similar reason as Google. CNIL found that Facebook made it harder for users to reject cookies, violating their freedom of consent. Facebook was given three months to fix this or face further penalties.

Amazon – $38 million

Although the fine was small compared to others, it serves as a reminder of the importance of following cookie consent laws.

Understanding the Cookie Consent Banner

A cookie consent banner is a specific type of consent banner focused on cookie usage. Cookies are small data files that websites use to track user behavior, improve functionality, and enhance marketing efforts. For example, websites use cookies to store login information, track user activity, and serve targeted ads. Privacy laws like GDPR and CCPA require that users are informed about these cookies and give explicit consent before they can be deployed.

Different Types of Cookies That Require Consent

• Necessary Cookies: These cookies are essential for basic website functionality and do not require consent (e.g., shopping cart cookies).
• Analytics Cookies: These cookies track user behavior on the website and require user consent (e.g., Google Analytics cookies).
• Marketing Cookies: These cookies are used for targeting ads and tracking users across websites, requiring explicit user consent.

How to Set Up a Cookie Consent Banner with Google Tag Manager

Implementing a cookie consent banner with Google Tag Manager simplifies cookie management and ensures compliance with privacy laws. Google Tag Manager allows you to trigger specific scripts and cookies only after user consent is obtained, giving you full control over how cookies are deployed.

Step-by-Step Guide to Implementing Cookie Consent

• Design Your Cookie Consent Banner: Create a banner that clearly explains cookie usage and allows users to accept or reject cookies.
• Add Google Tag Manager Code to Your Website: Install the GTM code in your website’s HTML.
• Create Triggers for Cookie Activation: In GTM, set up triggers that will deploy cookies based on user consent. For example, analytics cookies should only be triggered if the user accepts tracking.
• Test and Monitor: Once implemented, regularly test your consent banner to ensure it works properly across all devices and complies with privacy laws.

Benefits of Using Google Tag Manager for Consent Banners

Google Tag Manager offers several advantages when managing consent banners and cookies, making it the ideal tool for businesses looking to simplify consent management.

Why Google Tag Manager is Ideal for Cookie Management

• Centralized Control: With GTM, you can control all your cookies and tracking scripts from one place. This simplifies the process of adjusting cookie behavior when privacy laws change.
• Seamless Integration: Google Tag Manager integrates smoothly with Google Analytics, ensuring that your tracking is consistent across platforms.
• Granular Consent Triggers: Google Tag Manager allows you to create custom rules for when cookies are activated, based on user consent.

Using Consent Mode in Google Tag Manager for Enhanced Data Privacy

Google Tag Manager Consent Mode is a feature that allows businesses to adjust how Google tags behave based on the consent status of users. This is particularly useful for businesses using Google Analytics, Google Ads, or other Google services. When users opt out of marketing cookies, for example, Consent Mode ensures that Google Ads tags do not collect personal data, but can still measure ad performance in a privacy-safe way.

How Consent Mode Works with Google Analytics

When using Consent Mode with Google Analytics, data such as page views and conversions are still tracked, but personal identifiers are not. This helps ensure compliance with regulations while still maintaining useful data insights.

Customizing Consent Banners for GDPR and CCPA Compliance

GDPR and CCPA require explicit consent for certain cookies, and failure to comply can result in significant fines. Customizing your consent banner for these regulations is crucial.

Key Compliance Requirements for GDPR and CCPA

• Explicit Consent: Users must opt-in to non-essential cookies.
• Easy Opt-Out: Users should be able to easily withdraw their consent at any time.
• Detailed Privacy Policy: Provide a clear link to your privacy policy, explaining what data is collected and why.

Case Study: US Retailer Achieves CCPA Compliance

A major U.S. retailer was able to become fully compliant with CCPA by customizing their cookie consent banners to include a detailed opt-out option and implementing a user-friendly design. This not only reduced legal risks but also resulted in a 20% increase in customer trust.

Best Practices for Designing a User-Friendly Cookie Consent Banner

Designing a consent banner that complies with privacy laws while maintaining a good user experience is key to retaining user trust. Here are a few best practices:

• Minimal Disruption: Ensure the banner is not intrusive but still catches attention.
• Clear Options: Provide users with clear options to accept, reject, or customize their cookie preferences.
• Transparency: Explain what each category of cookies does, and why it benefits the user.
