Google Shopping Product Listing ads are data-feed driven product listing adverts that appear in Google when a user searches for a product. This differs from Google Search Ads as it provides more detailed information to the user such as a product image, price, style, buying options and much more.
These ads tend to appear at the top before any search ads in a carousel format and also within Google’s Shopping Tab. They are designed to help a high intent user connect to a product. Unlike Google Search, Google Shopping relies on the information you provide in the data-feed to match to the search term.
