How it fits together

  • A campaign belongs to a brand and targets one or more audiences.
  • An audience is built from data stores: YouTube channels and videos, with their comments.
  • Fandom generates targeting for each audience: keywords, segments, topics and websites.
  • When it’s ready, create the campaign in Google Ads. It starts paused.
Audience Exploration shows who an audience is on YouTube: the channels they also watch, and how those channels group. It’s invite-only for now.
