This feature allows you to target up to four subdirectories per domain. Subdirectory URL Targeting ensures your ads serve on all pages within the specified subdirectory path. For example, if you target nytimes.com/section/world/africa, your ads will serve in the World/Africa section, as well as any subsections beneath it.

To set this up, enter each URL on a separate line in the ‘Custom Audience’ text box. Remove ‘https://’ and ‘www.’ if applicable. Each list can contain up to 50,000 URLs.
