facebook ad audience settings
Although it has suffered a bit due to privacy changes, Facebook targeting is still some of the most powerful because users provide such detailed information about themselves on the platform – their age, relationship status, job, interests, and more. There are three types of audiences you can target with Facebook ads.
Primary Audience : Target users based on their demographics, interests and behavior.
Custom Audiences : Target and retarget customers women database and leads. They are pixel-based.
Lookalike Audiences : Target audiences that are similar to your existing customers and potential buyers.

For detailed targeting, you can create rules so that your ad targets users with one OR another, or one AND another interest. In any case, it’s best to stick to just one or two interests or demographics for each ad set. Otherwise, you won’t know which audiences are working for you. If you have more interests, you can always create new ad sets.
On the right , the Audience Definition section tells you how big or small your audience will be based on the criteria you choose, and the Estimated Daily Results section tells you how many people you estimate you'll be able to reach based on your daily spend. Keep in mind that these are just estimates and aren't always 100% accurate, so take them with a grain of salt.
