In part we will refute the old foundations, and in some places we will clarify, updating them for the present and future. Have you noticed that by describing the avatars of customers to yourself and implementing email database methods to attract them, completely “wrong” people appear among your audience? This can sometimes alarm and even make you doubt yourself, think that you made a mistake somewhere. But everything is much simpler - too detailed targeting cannot work effectively in real life. No matter how hard we try, we can't cut off everyone else.
From personal experience this is learned very quickly, but we do not always pay attention to it. Even detailed ad targeting on Facebook and Instagram cannot give us just the right ones. For example, when launching ads for an audience of 21-50 years old, there will definitely be impressions and even transitions of those who are beyond this age. By limiting the regional affiliation "Location - People living here", we can get a lead (or even a client) from a different region. This is due not so much to the errors of the system, but also to psychology. Some people indicate not the most reliable information about themselves, do not allow tracking their location, behave inconsistently on the network or in principle are inactive.
