Ad campaign audience section only shows the 'Interests' in the search and select dropdown whereas Facebook has other sections like demographics and behavior too.
We included 'Demographic and Behavior' along with the pre-existing 'Interests' options for detailed targeting and audience controls.
Each interest, demographic or behavior that is searched by the user will show the audience reach('Size' for Interests and Behavior; 'Coverage' for Demographics) details.
This completes the loop on detailed targeting which was missing in our Ad Manager but provided by Facebook.
It was highlighted by a couple of customers during calls and we got an ideas board post too regarding this specific ask.
It was observed in multiple ads that failed with an error as the audience size was too small to deliver and expectation is to broaden the audience. This happens when you select too many behaviors and demographics, and as they have a set audience size attached to them it leads to small audience size that is not fit for publishing an ad.
