Cookieless Ad Share Barely Budged in Q1: 33Across Report

While awareness of cookieless alternatives is interesting, the more important question is how many marketers are actually using them. This report by 33Across, which provides cookieless programmatic infrastructure, trumpets news that cooklieless ad CPMs average 21% less than cookie-based CPMs. They are more coy about revenue share, giving industry-by-industry details but no total. My math, which could be wrong, puts the figure about 23% for Q1 2023, maybe up 2% from the quarter before.
