How Changes in Browser Privacy Impact Multi-Channel Advertisers: Navigating the Cookie Deprecation Challenge


In the ever-evolving digital landscape, advertisers who utilize multi-channel strategies face a significant shift. The changes in browser privacy, primarily through the deprecation of cookies, are setting a new playing field. This article delves into what cookie deprecation means, the challenges it creates outside the controlled environments of social media platforms, and the solutions that are emerging in response, such as server-side tracking. Additionally, we will examine why Google has delayed the formal deprecation of cookies and how other browsers and devices are already adapting.

Data Codes through Eyeglasses

What Are Cookies and Why Are They Being Deprecated?
Cookies have been the backbone of digital advertising, enabling advertisers to track user behavior across sites to create personalized ad experiences. However, concerns over privacy have led to a shift towards more secure and private browsing experiences. This shift is what we refer to as ‘cookie deprecation’, where the reliance on third-party cookies is being reduced in favor of protecting user data.

The Impact on Privacy and User Trust
As browsers phase out third-party cookies, the landscape of digital advertising must adapt to ensure that privacy standards are met while still delivering effective marketing strategies. This change is not just a technical adjustment but also a move to enhance user trust, a crucial element in the digital age.

Challenges in Multi-Channel Advertising

Tracking Difficulties Outside Social Media Platforms
With the deprecation of third-party cookies, advertisers face challenges in tracking user interactions outside social media environments. This makes it harder to measure the effectiveness of ads across different channels and to optimize marketing strategies based on comprehensive user data.

Impact on Attribution and Conversion Tracking
The inability to track users across platforms disrupts the attribution models that advertisers have traditionally used. This challenge complicates understanding which channels contribute to conversions, leading to potential misallocation of marketing budgets and resources.

Technical Solutions: Embracing Server-Side Tracking

What is Server-Side Tracking?
Server-side tracking is a method where data is sent directly from the server instead of the client’s browser. This approach reduces the reliance on cookies and enhances privacy by processing data more securely and compliantly.

Benefits Over Traditional Cookie-Based Tracking
Server-side tracking offers improved data accuracy, better privacy controls, and a reduced footprint on the user’s browser, which can enhance site performance and user experience. Additionally, it provides a more robust framework for tracking across devices and channels, which is crucial in a cookie-less world.

The Ongoing Transition in the Industry

Google’s Delay in Deprecation and Its Implications
While Google has announced plans to phase out third-party cookies, it has also delayed these plans multiple times. This delay gives advertisers more time to adapt but also prolongs the uncertainty in the industry. Advertisers must stay agile and forward-thinking to navigate this transition effectively.

How Other Browsers Are Setting the Pace
In contrast to Google, many other browsers like Safari and Firefox have already implemented strict limitations on third-party cookies. This proactive stance pushes the industry towards finding new solutions quicker and encourages innovation in privacy-friendly tracking technologies.


As the digital advertising industry moves away from third-party cookies, advertisers must navigate a new reality characterized by enhanced privacy standards and changing technical requirements. The shift towards server-side tracking and other innovative solutions offers a path forward. However, the industry must continue to adapt, innovate, and respect user privacy to thrive in this new era.
