Hi I have a post in my Facebook Page and i want to boost it with fb boost post engagements. As target i make USA, UK, CA, AUS As placement i make Feed News Only desktop and i disable Instagram and Audiance Network As budget i make 5$ per day But the bid suggested by fb ads is between 3$ et 5$ What am i doing wrong ? And how can i get low cost ? Others Viral sites realize a 0.01$ per engagement as a cost. But i don't know how they make it ?
