I’m interested as to who this is testing. I see double click coverage, Amazon coverage, and a tiny amount of Facebook, but missing a lot of large players in the adtech space. I don’t see Microsoft being explicitly called here. Then from the large scale independent companies I see none of them on here? Shouldn’t you try Trade desk, Magnite, Applovin, Criteo, Xandr as well? Then you would want to check vs data brokers as well; Experian, Equifax, Axciom, Epsilon, LexisNexus, Liveramp, and CoreLogic at minimum.
