Performance Max campaigns are Google's automated ad solution that uses machine learning to show your ads across Google's entire inventory including Search, Display, YouTube, and more. You set a goal like sales or leads and Google optimizes placements in real time. While they save time and can boost results, they require clear conversion tracking and work best when you trust the algorithm to distribute your budget where it performs best.
