What is the role of a product feed in a Microsoft Advertising shopping campaign?

The role of a product feed in a Microsoft Advertising shopping campaign is to provide detailed information about the products you want to advertise. The product feed is a data file that contains a list of your products and their attributes, such as title, description, price, image URL, availability, and unique product identifiers. Microsoft Advertising uses this product feed to create and display shopping ads to potential customers. The product feed allows Microsoft to accurately match user search queries with relevant products in your inventory. For example, if a user searches for 'red leather boots', Microsoft Advertising uses the product feed to identify products that match that search query and create a shopping ad featuring the product image, title, price, and other relevant details. A well-structured and accurate product feed is essential for the success of a shopping campaign, as it directly impacts the visibility, relevance, and performance of your ads.
