Ari Paparo and Eric Franchi are joined by Erez Levin, a former Googler who focuses on media and inventory quality. They dig into what “quality” really means in programmatic advertising, why short-term outcomes can be misleading, and how incentive structures have pushed spend toward lower-value impressions.


Takeaways

  • Quality is best understood through effectiveness, but most measurement overweights short-term signals. 
  • “Not all impressions are created equal.”  quality varies by context, format, and goal. 
  • Video definition loopholes led to premium pricing for lower-attention formats and contributed to market confusion. 
  • MFA, SPO, and curation are connected symptoms of incentives that reward cheap scale and vanity metrics. 
  • Verification helps, but quality needs to be addressed across the full media workflow, including experimentation and MMM. 
  • Agentic buying could either improve quality controls or make it easier to optimize only to what’s measurable in the near term. 
  • Publisher traffic declines reinforce the difference between commoditized content and differentiated journalism or creator-led media.
