What manual input will you need to provide when setting up a Performance Max for shop goals campaign?

When setting up a Performance Max for shop goals campaign, you must manually provide ad creatives (such as headlines, descriptions, images, and videos). Performance Max leverages these assets to generate various ad formats across Google's inventory. While Performance Max automatically optimizes creative combinations, ad placements, and bids to achieve your shop goals, it relies on your initial input of high-quality creative assets to build effective ads. Without your ad creatives, the system has no content to display.
