We must establish, for each one of the defined scopes, our objective public. It is clear that, through the electronic channel we can arrive simultaneously at all our objective public, but also is not clear that we do not have it to do in the same way and, perhaps, either in the same space. We must implement a specific strategy for each one of them, based on its characteristics and necessities, and of our objectives towards them. To put an example, in the case of a odontològica clinic that it wants to develop its strategy of marketing in Internet, it will be able to define different objective public from those who to go: clients or patients (real and potential), who are the final adressees of their service; possible prescriptores (doctors, associations of patients...), that are one of the sources of provision of new clients; or other public (for example the press.), who can cover other objectives with notoriety or information that can interest to us. Therefore, we will have to establish priorities, objectives and to define the conceptual scopes in which we will act for each one of them.
