Brands may feel that they have little choice but to trust the platforms to define the measurement standards, and/or to certify third-party measurement tools on platforms like Facebook, Amazon, and Google. (Amazon, for example, invites brands to connect their first-party data to Amazon's audiences via the Amazon Marketing Cloud, and partnered with iSpot and VideoAmp for video-ad measurement, as reported in May. Google, meanwhile, created the YouTube Measurement Program, or YTMP, to vet those who monitor audience data on its own site.)
