What's a best practice to follow when creating a Performance Max campaign?
Correct: Use the maximum number of text, image, and video assets possible
The selection is correct because using the maximum number of text, image, and video assets possible provides Google’s AI with the diverse building blocks necessary to dynamically assemble the most relevant ad combinations for every unique user and placement across the entire Google Network. Since Performance Max is a cross-channel solution spanning Search, YouTube, Display, Discover, and Maps, providing a full variety of high-quality headlines, descriptions, and visual media allows the machine learning algorithm to perform extensive A/B testing at scale. This "asset-centric" approach ensures that the AI can optimize for specific consumer contexts—such as showing a short video to a mobile user on YouTube or a high-impact image to someone browsing the Discover feed—which leads to higher Ad Strength ratings and significantly better conversion performance compared to campaigns with limited or repetitive creative inputs.
