This research had the purpose of understanding the strategy and usability of the badges in the context of the Web 2.0, name given to the current Internet phase. The badges are excerpts of codes that some websites make available to be coupled one with another, with the function of importing the content - generated by users or not - in a dynamic way. The given hypothesis affirms that the non existence of clear orientations about the best way to announce the availability of badges in a website and the lack of an amount of good practices to turn the usage of the badges simple, easy and, mainly, viral can be an impediment to the usage of this resource by a biggest number of people. To prove this hypothesis it was used a methodology of research based on questionnaire sent to the authors of blogs - virtual diaries of easy update inside the context of the Web 2.0. According to the results, it s possible to affirm that these users already use badges, they believe that badges aggregate value to their blogs and are a way of bringing published content (by them or not) into the their blog. It s clear that the choice of badges isn t centralized, occurring mainly in websites where the blogger usually goes to and/or other blogs that already use badges. It s also evident the necessity of identifying the badges using an icon and a name.
