Cookie Banners, GDPR and the Future of Customer Data

Cookie banners were created to give customers more transparency about how their data is used online. In theory, they help people understand what information websites collect and allow them to make informed decisions about their privacy.

In reality, most people simply click “accept” or “reject” as quickly as possible so they can continue browsing.

In this episode of Winning With Shopify, Nick Truman sits down with Chris from the Data & Marketing Association (DMA) to explore the complicated world of cookie banners, GDPR, consent rules and customer data. The conversation reveals why many marketers, regulators and businesses now agree on one thing: cookie banners are not working the way they were originally intended.

Why Cookie Banners Are So Frustrating

For many internet users, cookie banners have become a daily annoyance.

Instead of providing meaningful transparency, they interrupt the browsing experience and present information that most people don’t understand. Terms like “cookies,” “identifiers,” and “data processing” often appear in long blocks of legal language that make it difficult for the average visitor to grasp what is actually happening.

Because of this, most users simply click the quickest option so they can move on with what they were trying to do. That behaviour means the banner rarely leads to genuine, informed consent — which was the original purpose behind the regulation.

From a customer perspective, the system creates confusion. From a business perspective, it creates operational challenges.

The Hidden Impact on Ecommerce Businesses

For ecommerce brands, data plays a crucial role in understanding how customers interact with their store.

When analytics tools are blocked or limited by cookie consent settings, businesses may lose visibility into important behaviours such as product views, checkout drop-offs or conversion rates. Without accurate data, it becomes much harder to identify problems, improve the user experience or optimise marketing campaigns.

Some businesses have even seen revenue decline after implementing stricter cookie banner configurations that limit the ability to track customer activity.

Without the right insights, companies struggle to understand why customers are abandoning carts, which marketing campaigns are working or how to improve their store’s performance.

Privacy Laws Are About Balance

A key theme of the discussion is that privacy legislation is not meant to stop businesses from using data altogether. Instead, it is designed to balance two important principles: protecting individual privacy and enabling businesses to operate effectively.

Under GDPR, privacy is considered a fundamental right. However, it is not the only right that matters. The law also recognises the right for businesses to conduct commercial activity and serve customers.

This is where the concept of balance becomes important. Companies must consider how their data usage affects customers while still maintaining the ability to attract, retain and serve those customers effectively.

When implemented properly, privacy laws should support both goals rather than forcing businesses to sacrifice one for the other.

Understanding First-Party, Second-Party and Third-Party Data

Another important topic in the conversation is the different types of data used in digital marketing.

First-party data is collected directly from a company’s own customers through its website, transactions or interactions. This is generally considered the most valuable and reliable type of data because it comes straight from the relationship between the business and the customer.

Second-party data involves information shared between trusted partners. A good example would be loyalty programs where airlines, hotels and car rental companies share points and rewards data within a defined partnership.

Third-party data is collected by external platforms or networks, often through advertising technology. This type of data has become more controversial in recent years as privacy regulations tighten and browsers limit tracking.

As the digital landscape evolves, many businesses are shifting their focus toward first-party data strategies that rely more heavily on direct customer relationships.

Why Customers Actually Appreciate Good Data Use

Interestingly, most customers do not object to companies using data when it improves their experience.

People often appreciate personalised recommendations, relevant offers and loyalty rewards that reflect their interests and buying habits. A retailer that remembers what a customer likes and provides helpful suggestions can create a much better experience than one that treats every customer the same.

The real problem arises when customers feel confused about how their information is being used or believe their data is being shared widely without their knowledge.

Clear communication and transparency can help solve this problem without overwhelming customers with technical details.

The Importance of Clear, Human Privacy Messaging

One of the most practical takeaways from the episode is how businesses communicate their privacy practices.

Many companies rely on lawyers to write privacy policies and data notifications. While legally accurate, these documents are often written in complex language that ordinary customers struggle to understand.

A more effective approach is to write privacy messaging in the brand’s own voice. When businesses explain clearly why they collect certain information and how it benefits the customer, people are far more likely to trust the process.

Simple explanations such as why a date of birth is requested or how customer preferences help improve product recommendations can significantly increase trust and engagement.

What the Future of Cookie Banners Might Look Like

There is growing momentum in the UK and other regions to simplify cookie rules and reduce the reliance on intrusive consent banners.

Recent legislation has already introduced some exemptions for certain types of cookies, such as those used for analytics or essential website functionality. While cookie banners are unlikely to disappear overnight, regulators and industry groups are actively exploring ways to reduce their complexity.

The long-term goal is to create a system where customers remain protected and informed while businesses can still access the insights they need to operate effectively.

The Takeaway for Shopify and Ecommerce Brands

For ecommerce brands and Shopify merchants, understanding customer data is becoming more important than ever.

At the same time, businesses must ensure that data is used responsibly and transparently. The goal should always be to improve the customer experience rather than simply collecting information for its own sake.

When handled correctly, customer data becomes a powerful tool for improving products, refining marketing strategies and building long-term relationships with customers.
