Narrowcasting of virtual cultural portals: the cases of Barcelona's Botanic Gardens and the Boí valley

This article aims to explain the reasons behind the success of a cultural resource on the internet. It is not always the number of hits that determines this success, instead they need to be used by specialist groups and in the context of cultural dissemination, education and research. The aim in defining the key concepts of cybermetrics, the discipline that studies the quantitative description of the content and communication processes seen on the internet, is to show how the narrowcasting of cultural resources to groups of interest is more important than general broadcast over the internet.
