Previewing AI-assembled Performance Max creatives before launch

AI-powered Performance Max campaigns automatically combine creative assets across placements, and Ad Preview Hub lets marketers preview those combinations, share secure review links, and collect stakeholder approvals across devices before activation so they can catch presentation, policy, and brand-fit issues early.

Why the human is still essential here

Marketers and reviewers still need to judge brand fit, messaging quality, compliance, client communication, and whether the generated asset combinations are acceptable for launch.
