Which configuration is necessary before launching a Performance Max campaign?

Before launching a Performance Max campaign, having a product feed in the Merchant Center is essential. This is because Performance Max campaigns are designed to leverage various Google channels to promote products effectively. The campaign uses the information from the product feed to understand what products are being advertised, their availability, pricing, and other relevant details.

The product feed serves as the foundation for how products are displayed across Google’s different platforms. Without this feed, Google cannot access vital data needed to optimize the ads, create relevant creative assets, or ensure the campaign is aligned with the user's intent when they search or browse online.

While keywords, enhanced conversions, and assets are important components in digital marketing, they do not hold the same fundamental importance in the initial setup of a Performance Max campaign as the product feed does. The product feed is crucial for driving the ads that showcase the products to potential customers.
