How to be successful in navigating digital marketing in a cookieless-era

Imagine browsing the internet and noticing that the ads you usually see, tailored to your interests and recent searches, are no longer there. This scenario is about to become a reality as major web browsers like Google Chrome, Mozilla Firefox, and Apple Safari phase out third-party cookies. This significant shift, especially with Chrome's substantial market share (52% in the US and 63.6% globally), is set to redefine the landscape of digital marketing.

Third-party cookies have been the backbone of digital advertising for years, tracking users across various websites to collect data that shapes marketing strategies. However, starting in Q1 2024, Chrome users will experience a web without these cookies, with the change reaching all users by Q3 2024.

This move is more than just a technical update; it's a disruption in the digital advertising industry. Cookies have long been the go-to method for tracking online activities for targeted advertising. With this method on its way out, marketers and advertisers must pivot to new ways of collecting consumer data and measuring campaign effectiveness.

As we face the challenge of a post-cookie world, it's crucial to explore and understand alternative strategies for behavioral targeting and building a marketing data pipeline. But first, let's take a quick look at the rise of third-party cookies and how they became such an integral part of digital advertising. Understanding this history will help us grasp the significance of the shift and better prepare for the changes ahead.

Preparing for the Phase-Out of Third-Party Cookies in Digital Marketing

In response to concerns over user privacy and regulations, web browsers like Google Chrome, Mozilla Firefox, and Apple Safari are phasing out third-party cookies. Starting in Q1 2024, Chrome users will have third-party cookies disabled. The percentage of users affected will gradually increase to 100% by Q3 2024. 

Since Chrome has a significant share in the web browser market (52% in the US and 63.6% globally), any changes such as this will significantly impact digital marketing.

Third-party cookies have been crucial in customizing the user experience for several years. They form the backbone of the digital marketing and advertising industry, keeping tabs on users across various platforms and gathering data that businesses analyze to shape their marketing strategies.

This move is set to disrupt the digital advertising industry, which could shake up its existing practices. Cookies have been the primary means to track online activities for targeted advertising, but this method is no longer viable. 

Therefore, marketers and advertisers must find alternative means of collecting consumer data and improving their campaign measurement by utilizing behavioral targeting to build a marketing data pipeline. Let's take a step back at how third-party cookies came to be. It's important to understand this before figuring out what we can do to get past them.

The rise and success of third-party cookies

1990s—Lou Montulli, a programmer at Netscape, invented cookies. The initial concept was straightforward: when a user visited a website, the site would send a small piece of data (a cookie) to the user's browser, which the browser would store locally. 

When the user revisits the website, the browser sends the cookie back to the website, allowing the site to remember the user, whether for keeping items in a shopping cart, saving login information, or tracking user behavior across sessions.

As the internet evolved, the use of cookies expanded well beyond these initial purposes. They became a crucial tool for tracking user behavior across different sites, enabling targeted advertising, and collecting data for analytics.

Here is an illustration that shows the data and cookie flows involved in a typical programmatic ad call. 

This indicates that whenever customers browse a website or use a mobile app, their information is shared with multiple companies, who may further share it with other third parties. All this is usually done to display more relevant ads or to show them an advertisement for a product they previously viewed.

The downfall and collapse of third-party cookies

2000s—As internet usage surged, so did the use of third-party cookies for targeted advertising. This led to increasing privacy concerns among users and regulators, as many were unaware of the extent of their online tracking.

As an example:

  • You're shopping online for a new pair of running shoes. After browsing a few sports websites, you notice that almost every other site you visit, even those unrelated to sports, starts showing ads for running shoes. This is third-party cookies at work, tracking your browsing habits and serving targeted ads across different websites. While it might seem convenient initially, it can quickly become intrusive, especially if the ads persist long after you've made a purchase or if you start seeing ads for unrelated products based on your broader browsing history.
  • When researching something as important as a home loan, you take the necessary steps to be mindful of your online activities and the potential for your data to be tracked and used for advertising purposes. However, with this cookie enabled, your personal information is being exploited. The ability to track user behavior across multiple websites was unprecedented, resulting in increased attention from privacy advocates and regulators. Strict privacy laws, such as GDPR in Europe and CCPA in the United States, were introduced in response to the growing demand for greater transparency and control over personal data.

Although third-party cookies have played a crucial role in shaping the modern advertising landscape on the Internet, their drawbacks are mainly related to user privacy and security. These concerns grew as the internet became more integrated into daily life. It became necessary to inform people how much of their online activity was being tracked and used. 

Shifting towards a more privacy-focused web

Enhancing the user experience is vital for brands to encourage data sharing and build customer relationships in this transitional period. There is a growing trend towards a more privacy-focused web, where customers are becoming increasingly concerned about the security of their personal information and online activities. 

With the growing advancements in AI and machine learning technologies, businesses increasingly emphasize protecting user privacy by implementing robust security measures and data encryption protocols. 

This includes using privacy-centric browsers, VPNs, and other tools that allow users to control their online privacy and safeguard their data from prying eyes. This raises the stakes for businesses to smartly cut through the noise and meaningfully connect with their target audience.

This shift has led to alternative methods of tracking and advertising. On the cusp of a new era, these include reliance on first-party data, contextual advertising, identity resolution solutions, and new frameworks like Google’s Privacy Sandbox.

The Way Forward: Collaboration and Innovation 

This transition period will be critical for the industry to adapt to new norms and for customers to adjust to changes in online advertising practices. This era marked a significant shift in the future of digital advertising. 

This means that success will rely on more than just a single strategy but a collaborative and innovative approach. This collaborative effort will likely result in the development of new strategies to navigate this new landscape.

Effective collaboration between advertisers, tech companies, and marketers is crucial in developing standards that balance user privacy, data security, and effective advertising. They must work together to navigate the challenges and opportunities the evolving online ecosystem presents.

What should marketers be doing right now?
