Digital marketing has entered a new era where privacy concerns and regulatory changes are reshaping how businesses can reach their audiences. The phasing out of third-party cookies by major browsers like Chrome has sent marketers scrambling for alternatives to traditional retargeting methods. This shift isn’t just a technical hurdle—it represents a fundamental change in how online advertising functions.

Retargeting (also known as remarketing) has traditionally relied on tracking cookies to identify users who have previously visited a website, allowing advertisers to show tailored ads as these users browse elsewhere online. With third-party cookies disappearing, businesses must adapt to new technologies and strategies to maintain effective retargeting campaigns.

This article explores practical, forward-thinking approaches to retargeting without relying on traditional tracking cookies. We’ll examine alternative technologies, first-party data strategies, and innovative approaches that respect user privacy while still delivering the personalized experiences that drive conversions.

Practical Perspective for Market

The digital advertising landscape is undergoing a seismic shift. Third-party cookies, once the backbone of targeted advertising, are being eliminated due to growing privacy concerns, regulatory pressure, and changing consumer expectations. This isn’t merely a technical challenge but a fundamental market transformation.

Several key factors are driving this change:

• Browser restrictions: Chrome (with over 60% market share) is following Safari and Firefox in phasing out third-party cookies
• Privacy regulations: GDPR, CCPA, and other privacy laws worldwide restrict data collection practices
• Consumer awareness: Users are increasingly concerned about how their data is collected and used
• Technical evolution: Mobile apps and cross-device browsing already operate largely without cookies

According to Stape.io, while Google’s timeline for eliminating third-party cookies has been extended, the industry is actively developing and implementing cookieless targeting solutions. These aren’t just stopgap measures but represent the future of digital advertising.

The market is responding with innovation. Advertising platforms are developing privacy-centric alternatives, and businesses are shifting focus to first-party data collection. This transition period offers forward-thinking marketers an opportunity to gain competitive advantage by mastering new retargeting methodologies before they become the only option.

Practical Analysis for Businesses

For businesses accustomed to cookie-based retargeting, the transition to cookieless methods requires a strategic reassessment of targeting capabilities. Let’s analyse the practical alternatives available today.

First-Party Data Strategies

First-party data—information collected directly from your audience with their consent—is becoming the gold standard for retargeting. MeasureU emphasises that businesses should prioritise building robust first-party data collection systems.

Key first-party data collection methods include:

• Email newsletter subscriptions
• Account creation and login systems
• Progressive profiling through quizzes or preference centres
• Purchase history and CRM data
• Mobile app usage data

Contextual Targeting

Rather than tracking users across the web, contextual targeting focuses on placing ads in relevant content environments. This approach doesn’t require personal data but instead analyses the content of webpages to determine ad relevance.

According to MeasureSchool, contextual targeting is experiencing a renaissance as cookie-based options decline. Modern contextual targeting uses advanced AI to understand content nuances, allowing for sophisticated targeting without privacy concerns.

Platform-Based Solutions

Major advertising platforms like Google, Facebook, and Amazon have developed their own solutions that don’t rely on third-party cookies:

Actionable Benefits for Businesses

Moving beyond cookies isn’t just a necessary adaptation—it offers distinct advantages for forward-thinking businesses. Here are the tangible benefits of embracing cookieless retargeting:

Improved Data Quality

First-party data strategies typically yield higher-quality information than third-party cookies ever could. When users willingly provide information through accounts, subscriptions, or purchases, the resulting data is:

• More accurate and reliable
• Legally compliant with privacy regulations
• Longer-lasting than cookie-based identifiers
• Exclusive to your business (not shared with competitors)

Enhanced Cross-Device Capabilities

Cookie-based tracking has always struggled with cross-device identification. RevBoss points out that identity-based solutions like email or login IDs provide seamless cross-device tracking, allowing businesses to maintain consistent messaging regardless of which device a customer uses.

Reduced Ad Waste

Cookie-based retargeting often suffers from frequency capping issues and targeting inaccuracies. Cookieless approaches like contextual targeting can reduce ad waste by:

• Eliminating duplicate targeting across devices
• Preventing ads from following users long after purchase
• Focusing budget on genuinely interested audiences
• Avoiding brand safety issues through better content alignment

Improved Customer Trust

According to Claire Pells, businesses that transparently collect and use first-party data build stronger customer relationships. By respecting privacy preferences and being clear about data usage, companies can turn privacy concerns into a competitive advantage.

Actionable Case Study for Industry

How Adidas Transformed Its Retargeting Strategy

The Adidas case demonstrates that businesses can not only survive but thrive in a cookieless environment by investing in direct customer relationships. Their approach prioritised creating value exchanges where customers willingly shared information in return for improved experiences.

As Business Directory and other business directories have long understood, categorising and contextualising businesses creates value without requiring invasive tracking. Adidas applied similar principles by focusing on context and direct relationships rather than tracking pixels.

Actionable Perspective for Businesses

To successfully implement cookieless retargeting, businesses need a structured approach that balances technical solutions with strategic thinking. Here’s a practical framework for moving forward:

1. Audit Your Current Retargeting Dependencies

Begin by thoroughly assessing your current reliance on third-party cookies:

• Which marketing campaigns depend on cookie-based retargeting?
• What percentage of your conversions come from retargeting efforts?
• Which platforms and tools in your stack rely on third-party cookies?
• What first-party data are you already collecting?

2. Prioritise First-Party Data Collection

Develop or enhance systems to collect and activate first-party data:

Effective first-party data collection methods include:

• Email capture with progressive profiling
• Account creation with clear benefits
• Mobile app downloads with permission-based tracking
• Loyalty programmes with preference centres
• Interactive content requiring registration

3. Implement Server-Side Tracking

Server-side tracking sends data directly from your server to advertising platforms, bypassing browser-based cookie restrictions. According to MeasureSchool, implementing server-side tracking through Google Tag Manager Server-Side or similar solutions provides more control and resilience against browser restrictions.

4. Explore Privacy-Safe Identifiers

Several industry initiatives are creating privacy-compliant alternatives to cookies:

• Unified ID 2.0 (email-based, encrypted identifier)
• Google’s Privacy Sandbox and Topics API
• LiveRamp’s Authenticated Traffic Solution
• ID5 Universal ID

5. Test and Measure New Approaches

Run parallel campaigns using both cookie-based and cookieless approaches to compare performance and prepare for the transition:

• A/B test contextual vs. behavioural targeting
• Compare performance of first-party vs. third-party audiences
• Evaluate different identity solutions for reach and conversion

Strategic Facts for Businesses

To make informed decisions about cookieless retargeting, businesses need to understand the key facts shaping this transition. Here’s what you need to know:

The Timeline Reality

While Google has extended its timeline for removing third-party cookies from Chrome, the direction is clear. According to RTB House, Google is gradually restricting third-party cookies for 1% of Chrome users as of January 2024, with plans to increase this percentage throughout 2025. This phased approach provides a testing ground for alternatives, but the complete deprecation remains inevitable.

Privacy Regulation Impact

The cookieless future isn’t just being driven by browser changes—it’s also shaped by regulations:

• GDPR in Europe requires explicit consent for tracking
• CCPA/CPRA in California gives users the right to opt out of data sales
• LGPD in Brazil establishes similar consent requirements
• More regional regulations are expected to follow these models

These regulations are creating a global patchwork of requirements that make cookie-dependent strategies increasingly complex to manage legally.

Performance Realities

Early adopters of cookieless strategies are reporting mixed but promising results:

• Contextual targeting is showing 80-90% of the performance of cookie-based retargeting in some sectors
• First-party data strategies typically deliver higher conversion rates but with more limited reach
• Server-side tracking solutions maintain approximately 70-85% of event data compared to client-side tracking

Walled Gardens Are Growing Stronger

The cookie apocalypse is strengthening the position of major platforms with logged-in users. According to Visable, platforms like Google, Facebook, and Amazon are developing their own identity solutions that work within their ecosystems, potentially increasing advertiser dependency on these platforms.

This consolidation makes diversification of marketing channels increasingly important. Business directories like Business Directory offer an alternative channel that doesn’t rely on invasive tracking while still providing targeted visibility to relevant audiences.

Strategic Facts for Operations

Implementing cookieless retargeting requires operational changes across your marketing technology stack and processes. Here are the key operational considerations:

Technical Implementation Requirements

Moving to cookieless retargeting typically requires several technical changes:

• Server-side tagging infrastructure: Setting up server-side tag management systems to maintain tracking capabilities
• First-party data storage: Implementing secure, compliant customer data platforms (CDPs) or data warehouses
• Identity resolution systems: Adopting tools that connect user touchpoints across channels without cookies
• API integrations: Developing direct connections between your systems and advertising platforms

Resource Requirements

According to MeasureU, the transition to cookieless retargeting requires specific resources:

• A/B testing methodologies need adaptation

To address these challenges, businesses are adopting marketing mix modeling (MMM) and incrementality testing alongside traditional attribution models.

Budget Implications

The transition to cookieless retargeting has several budget implications:

While the transition requires investment, businesses that adapt early typically see costs stabilise and performance improve as their systems mature.

Strategic Conclusion

The end of third-party cookies isn’t the end of effective retargeting—it’s an evolution toward more sustainable, privacy-centric marketing practices. Businesses that view this transition as an opportunity rather than an obstacle will emerge with stronger customer relationships and more resilient marketing systems.

Key Action Steps
