Rethinking Attribution with Jeff Greenfield of Provalytics

In the latest episode of the Hot Pursuit podcast, sponsored by Leadpost, the conversation turned to an increasingly crucial topic in digital marketing: the future of attribution in the era of cookie deprecation. Host Ro was joined by Jeff Greenfield, CEO of Provalytics, to explore how the digital landscape is shifting and what this means for marketers.

The Cookie Conundrum

Greenfield’s journey in digital marketing measurement began on the brand side before moving to agency work, where he tackled the problem of overcounting in attribution. This led him to develop one of the early multi-touch attribution platforms, C3 Metrics. His experience highlighted a key challenge: accurately attributing conversions in a fragmented digital world.

With Google’s upcoming phase-out of third-party cookies, following similar changes by Safari, the industry faces a major shift. The central question is: What changes are coming, and when?

Understanding the Shift

The removal of third-party cookies will drastically change how advertisers target and measure campaigns. Greenfield points out that while hyper-targeting and last-click attribution have dominated, they’ve led to higher costs and a limited view of the customer journey. As cookies become obsolete, marketers need to rethink their strategies and embrace more holistic measurement practices.

 

Back to Basics: The Role of Impressions

Greenfield suggests a return to fundamental advertising principles. Instead of focusing solely on clicks and conversions, understanding impressions—how often an ad is displayed—can offer valuable insights into reach and brand awareness. This shift emphasizes long-term impact and overall campaign effectiveness over immediate click-based results.

He advises marketers to track impressions and analyze trends to gauge the broader impact of their campaigns and make informed decisions beyond immediate sales. This approach enables a more accurate assessment of campaign effectiveness and strategic adjustments.

 

The New Measurement Paradigm

As digital advertising evolves, so does the need for advanced measurement techniques. Provalytics offers a solution that bridges the gap between traditional multi-touch attribution and the new cookie-less era. By utilizing non-user-level data and advanced mathematical models, Provalytics provides insights into campaign effectiveness without relying on personal data.

Greenfield highlights the importance of combining historical data with sophisticated algorithms to deliver actionable insights. This approach enables marketers to optimize their budgets effectively across both digital and traditional media channels, providing a comprehensive view of campaign performance.

 

Looking Ahead

The shift from third-party cookies presents both challenges and opportunities. Marketers must reassess how they measure and attribute their efforts, embracing a broader perspective on impressions and long-term impact for more effective strategies and better ROI.
