Best Practices for Using Product Listing Ads

Bidding efficiently at your most granular target level(s) is the best way to maximize your product feed's potential.

3. Always have a "catch all" target. Since you can't bid on specific keywords for PLAs, and search queries are matched by the unique product titles and descriptions, it's important to have a "catch all" or "all products" target in your campaign. By neglecting to do so you run the risk of missing traffic to relevant products in your feed.
