With audience exclusions, you can set up targeting rules to avoid showing some products in your dynamic ads to people in your audience. For example, you could set up a targeting rule that excludes purchases from your website in the past 30 days. You can create audience exclusions when you're retargeting people who visited and took action on your website or in your app, or when you're targeting a broad audience.

Audience exclusion basics

To exclude people from your dynamic ads audience, you need to set up an exclusion. Bear in mind that exclusions are based on products in your catalogue; not based on the people in your audience. Even if someone in your audience has previously purchased a product from your catalogue, it doesn't mean that they are automatically excluded from your ads.

For example, you decide to target people who viewed products on your website but didn't purchase anything within the past 28 days.

Alice visits your website and views three products from your catalogue. She decides to purchase two of the products. Because not all products were purchased, Alice remains in the audience. If she decides to buy the third product, she will then be excluded from the audience.

Note: If you use the Marketing API, you can update your exclusion targeting to possibly exclude all people who have made a purchase from your catalogue. Learn more about creating audience rules with the API.
