The actions of SMM Social Media Marketing – have become the backbone of many marketing plans for some time. As social networks are gaining importance as sites preferred by the public, the obligation to be in social networks, and perform web promotion actions on this channel becomes noticeable. In principle, it is necessary to choose the social networks in which we participate consistently with the composition of our basic target. The truth is that every time there are more social networks and never better applied the saying that who covers much, little tightens, because it is unlikely to participate successfully in a large number of social networks, unless a division to deal with especially this is available. Can social networks not be automated, at least not at 100%, i.e., is not possible to base all entries on social networks in applications that allow us to post messages in several networks at once. For this reason, this type of communication requires a high level of personal presence, given that precisely what interesting is the Exchange that is generated between the company and the public, with the aim of creating community. Therefore, the choice of the networks in which we participate will be the first step that we will give our SMM strategy. Discover, try and experiment with the many tools that exist for monitoring of social networks. It is possible to know who let us follow, our influence in networks based on the level of participation, the degree of interactivity with reference to the amount of posts that we make, etc. For this reason, it will be necessary to select, at this stage, auxiliary tools that want to use, and that will also help us to extract even in any way-the cost per contact, and ROI return on invested – in these types of actions. Social networks take time. It is essential, in a first stage, understand how the flow of information is given in the selected network. The way in which people interact on Twitter, is not the same as in Linked In and Facebook, to give an example. Search for staff responsible for these issues with the necessary experience to carry out this important task: creating community and to develop a channel of permanent promotion of our products and services. Integrate your site to social networks. There should be a divorce between what is expressed as values on its website and the manner in which you presented in social networks. For this reason, it is also necessary to coordinate the actions of SMM with the traditional online marketing for example, PPC campaigns. In the initial stages, social networks are a bet for the future. But the benefit will be very large in terms of promotion of our site and our brands on the internet.
