One of the benefits of working with a large number of publishers is that we’re able to gain a deep understanding of their unique needs. As we’ve learned more about how publishers set up their ad stacks, we’ve realized that there are a lot of points that we cover over and over again.
Back in January, I posted the findings from an experiment we ran to measure what happens when you increase the number of header bidders, and how that impacts CPM. We found that there is a strong correlation between increasing bidders and increased average CPM performance; we saw a 58% increase in CPMs when running 6 bidders versus none.
As publishers, we must monetize, and those of us who aren’t in a monopoly position à la Google or Facebook are at the mercy of a fragmented and messy, but necessary, adtech ecosystem. It’s how thousands of us make money and it certainly has its problems and frustrations.
