Is There a Target for Facebook Ads?

A, i don't have experience doing this. I wrote a post about it probably, like six months ago. There was not clear targeting on facebook for who exactly we wanted go to. We were selling to somebody that took care of certain people an dimentia care and senor living facilities. And so i asked them if they would install the facebook pixtl on their sight. And they said yes. And id built the audience over a month. It was the only people that would ever go to that siteof those types of people. And there was 15 thousand.
