Adapting to new privacy rules and technology shifts is essential in digital advertising. Server-to-server tracking offers a solid alternative to traditional pixel-based tracking, which ad blockers and privacy measures now limit. This approach provides advertisers with reliable, accurate data for precise targeting and effective attribution. This article covers the basics of server-to-server tracking, its benefits, and its role in helping advertisers navigate today’s digital landscape.

Impact of iOS 14 on Advertising

‍

The introduction of iOS 14 marked a significant turning point in digital advertising.

The complex series of events that led to major disruptions in ad tracking includes:

• Initial rollout in March 2021 had limited immediate impact as the changes were not immediately apparent to users or advertisers
• Escalation of effects in July and August 2021 because more users updated their devices and opted out of tracking
• The critical role of FTC oversight in enforcing stricter compliance with user privacy choices compounded the impact of the iOS changes
• A cascading effect where opting out on one device led to tracking limitations across all of a user's devices, which significantly reduced the available data pool

This change resulted in a substantial reduction in available user data, forcing advertisers and platforms to adapt their strategies and technologies. The impact was particularly severe for platforms like Meta, which relied heavily on cross-app tracking for ad targeting and attribution.

The Role of Machine Learning in Digital Advertising

‍

The digital advertising landscape has been revolutionized by the integration of machine learning algorithms. Platforms like Google Ads and Meta (formerly Facebook) have become heavily dependent on these sophisticated systems to optimize ad delivery and performance.

‍

This shift has brought about several key changes:

• Simplified user interfaces that can be deceptively easy for amateur advertisers, potentially leading to a false sense of competence
• Dramatically increased power and capability of advertising platforms, allowing for more precise targeting and optimization
• The need for advertisers to adapt their strategies to work with, rather than against, these algorithms
• A shift from manual optimization to providing the right inputs and allowing the algorithms to optimize performance

Success in this new environment requires a fundamental understanding of the "game" being played. It's no longer solely about an advertiser's intuition or experience but about providing the right inputs to these sophisticated machine learning systems. This shift necessitates a new skill set for advertisers, focusing on data quality, creative diversity, and strategic input rather than manually tweaking campaign parameters.

Challenges with Current Tracking Solutions

‍

While many advertisers have implemented basic tracking solutions, such as Meta's Conversions API (CAPI), these often fall short of providing the comprehensive data needed for optimal performance.

‍

Common issues include:

• Homegrown solutions that may appear functional but often send incorrect or incomplete data, leading to misattribution and poor optimization
• Basic integrations like Shopify's Facebook sales channel that lack customization and nuance, failing to capture the complexity of modern e-commerce transactions
• Outdated systems that haven't kept pace with privacy changes and increased complexity in e-commerce, resulting in data gaps and inaccuracies
• Difficulty in accurately tracking and attributing conversions across multiple touchpoints and devices

These challenges underscore the need for more sophisticated, tailored tracking solutions that can handle the intricacies of modern e-commerce and advertising landscapes. Advertisers need systems that can provide accurate, real-time data while respecting user privacy and complying with evolving regulations.

Data Velocity and Cleanliness in Advertising

‍

The quality and speed of data transmission play crucial roles in the effectiveness of machine learning algorithms in advertising.

‍

Two powerful analogies illustrate this concept:

• Formula One race car engines: High-quality data is likened to premium fuel, essential for optimal performance. Just as a Formula One car requires the best possible fuel to perform at its peak, machine learning algorithms need clean, accurate data to make the best possible decisions.
• Clear windshield: Clean, comprehensive data provides clear visibility for accurate decision-making. If an algorithm only has partial or unclear data, it's like driving with a partially obscured windshield, leading to suboptimal decisions and performance.

While the exact impact of data velocity is difficult to quantify, the consensus among experts is that faster, more accurate data transmission leads to better algorithm performance and, consequently, improved ad targeting and efficiency. This emphasizes the importance of implementing robust server-to-server tracking solutions that can provide real-time, high-quality data to advertising platforms.

Understanding Server-to-Server Tracking

‍

Server-to-server tracking represents the next generation of data collection in digital advertising. This method is a significant leap forward from traditional pixel-based tracking, which relies on browser technology and is increasingly vulnerable to ad blockers and privacy measures.

‍

Server-to-server tracking offers several key advantages:

• Direct data transmission between servers, effectively bypassing ad blockers and ensuring data delivery
• Enhanced data integrity and reliability, reducing the risk of data loss or corruption
• Ability to send more comprehensive information, including hashed emails and phone numbers, which is crucial for precise targeting and attribution
• Improved compliance with privacy regulations, as sensitive data can be handled more securely

The implementation of server-to-server tracking has become particularly crucial in light of recent privacy changes, such as Apple's iOS 14 update, which has significantly limited the effectiveness of traditional tracking methods. For brands and advertisers, adopting this advanced tracking method ensures they continue to receive the high-quality data necessary to fuel their machine-learning systems and algorithms effectively.

Comparing Server-to-Server Solutions

‍

The market for server-to-server tracking solutions is diverse, with options catering to different business sizes and needs.

‍

Key players in the space include:

• Elevar: Focused on larger brands, offering comprehensive but complex solutions. Their strength lies in handling intricate e-commerce setups, which may be overkill for smaller businesses.
• Blotout: Known for privacy-focused solutions but with potential compliance risks. Their approach to data handling, while innovative, may raise concerns in some regulatory environments.
• Triple Whale: A newer entrant with room for improvement. While their offering is integrated into a broader e-commerce analytics platform, their server-to-server tracking solution is still maturing.
• Northbeam: Specializing in multi-touch attribution for larger brands. Their sophisticated approach is well-suited for businesses with complex, multi-channel marketing strategies.

Final Thoughts on Data and Performance

‍

Key takeaways for digital advertisers include:

‍

• The importance of moving beyond basic, free tracking solutions, which often provide incomplete or inaccurate data
• The significant performance improvements possible with better data, with many businesses seeing a 15-20% lift in ad performance after implementing advanced tracking solutions
• The need for a holistic approach combining quality data, creative excellence, optimized landing pages, and modern campaign structures
• The ongoing importance of human expertise in interpreting data and making strategic decisions, even as algorithms take on more operational tasks
