The power of Performance Max campaigns
If it’s part of Google, a Performance Max (PMax) campaign can be run on it. This means you have access to everything that is part of Google, including Search, Shopping, YouTube, Display, Gmail, and Discover. If it lives and breathes within the Google network, PMax has access and can run ads on it, which makes this a powerful way to put AI to work for your advertising. Instead of choosing channels and setting placements, you simply feed it and it does the rest. Set the goals, get a little creative, define the audience signals, and let PMax go to work for you.
