Google Performance Max: A Practical Guide for Advertisers
Performance Max is a Google Ads campaign type that uses Google's automation to show your ads across Search, Shopping, YouTube, Display, Discover, Gmail and Maps from one campaign. It works best with accurate conversion tracking, strong creative assets, a good product feed for eCommerce and clear audience signals. Without these, it can spend budget on low-value placements or on brand searches you would win anyway.
Performance Max (PMax) promises one campaign that finds customers everywhere Google shows ads. It can work very well, but only when you feed it the right inputs.

Setting it up well
Conversion goals
choose the actions that matter, such as purchases, qualified leads or calls, and give them values where possible.
Asset groups by theme
separate product categories or services, each with relevant headlines, descriptions, images, logos and videos.
Plenty of assets
give Google enough variety to test. Upload your own video; otherwise Google may auto-generate one.
Audience signals
your customer lists, website visitors and custom segments based on search terms guide the system early on.
Brand exclusions
where available, exclude brand searches so PMax does not take credit for customers who were already looking for you.
Feed quality (eCommerce)
clear titles, accurate categories, images and attributes.
