The product feed is like a digital list of all the items you're selling in your online store. This list includes important details about each item, like its name, price, picture, and other specific features (for example, for a shirt, it could include the color and size).
Think of it like a menu in a restaurant. Just like the menu provides information about each dish (ingredients, price, etc.), a product feed provides information about each product in your online store.
Let's make it simple : the more quality data reside in your feed, the more visible your products will be.
