What's the purpose of attributes in the product feed?

In a Google Merchant Center product feed, attributes are the data points that describe a product, acting as the standardized building blocks that allow Google's algorithms to understand exactly what you are selling. These attributes—which can include a mix of text, numerals, and URLs such as id, title, price, and availability—provide the structured information necessary to match your items to relevant user search queries. By providing a comprehensive set of these data points, you ensure that Google can accurately categorize your inventory and display high-quality, informative Shopping ads to the right audience at the right time.
