Resumen

In the first stage of the web its sites were replicas of corporate brochures, while the current trend of production and dissemination of information through the tools of the web 2.0, such as blogs or social networking sites, suggest that the content has become the privileged player. From that perspective, there is a need of having an order based on guidelines that determine both the hierarchy of texts and the layout of graphic elements. Therefore, efficient design and architecture of information should be built not only from an exclusively rational structure, but also take into account emotional elements relative to the experience of its use, mainly through its design. Only the combination of both enable users to feel comfortable before, during and after having visited a website.
