Facebook is migrating advertisers who currently use Connections Targeting to use Page Engagement Custom Audiences. Open up Marin Social, navigate to Audience, then choose Custom Audience and Page Engagement Custom Audience. From there, choose the option People who currently like my page to create such an audience. When creating or editing ads, add this audience using inclusion or exclusion to ensure your ads reach or do not reach page fans.
MarinOne will mirror the behavior of Facebook Ads Manager, which means users will no longer be able to use connections targeting when creating or editing campaigns. The corresponding fields will be removed.
Please note that existing campaigns that use connection targeting can continue to run as-is, as this update will only apply for new, edited campaigns.
