Damien Voita is Principal Campaign Manager at AdRoll, with nine years of agency and in-house experience in paid media and integrated campaign strategy. He covers a three-phase measurement model that moves from platform metrics like CTR and CPM to branded search impressions to year-over-year CPA comparisons. He also explains how to shift budget into open web channels like CTV, native display, and audio, and how to build third-party validation that LLMs recognize.
