You recently launched a new line of kombucha products with the plan of selling them at a popular big-box retailer. What extension should you use when setting up your Performance Max for store goals campaign?

For selling products at a big-box retailer, an affiliate location extension with a Google-curated chain is the correct choice. This extension allows you to show ads to users near participating retail chains that sell your products, even if you don't own those store locations. Since you're selling through a popular big-box retailer, you need to leverage their existing store network. A standard location extension with a Google-curated chain or Business Profile is used when you own and operate the physical store locations yourself. A Global Location Group is a way to organize multiple locations, but it's not the specific extension type needed to connect with third-party retailers.
