Why Use Product Listing Ads?
Product Listing Ads allow you to turn your product feed from the Google Merchant Center into shopping ads for each of the items you sell. By connecting AdWords with your Google Merchant Center account, you can then optimize and promote the items that people are looking to buy. The main benefits of using Product Listing Ads include:
Retail-Friendly Campaign Management
Since Shopping campaigns allow you to view your product inventory in AdWords, you can create ad groups for the items you want to bid on, making it easier to optimize your products.
Regardless of how you structure your Shopping campaigns, you’ll have the ability to view performance data by product, category, product type, brand, condition, item ID, or custom labels.
Within Shopping campaigns, you can see benchmark data for average click-through-rate and max cost-per-click, which can help you optimize your products against other competitors.
