Advertisers can choose to exclude questions and audiences in all of their ad sets.
Questions can be excluded individually in its respective search bar. You can also use the “Exclude Questions” button to find and exclude questions using keywords or a Quora Session URL.
To exclude an audience, you will first need to create an audience in the Audiences tab. This feature can be used to exclude website visitors (Website Traffic Audience), a list of existing customers via email (List Match Audience), and other customized audiences.
If you are using Keyword Targeting, you can exclude keywords in the “Primary Targeting” section of your ad set.
