In 2019 Facebook announced updates to Housing, Employment, and Credit Ads to help prevent discrimination in ads that offer those services.
If you want to reach people in the US with ads that offer housing, employment or credit opportunities, you must now select the corresponding “Special Ad Category” in the SmartBoost settings or in Ads Manager or your ad will not be able to run.
Campaigns that include a Special Ad Category have some limited or unavailable audience targeting options.
Special Ad Audiences are similar to Lookalike Audiences, but do not take into account age, gender or ZIP code when targeting
If you have any questions regarding Housing, Employment and/or Credit Ads please feel free to reach out to firstname.lastname@example.org
