Methods for configuring website categorisation software, categorising websites and a method and system for controlling access to websites. A number of websites are selected, all of which relate to a single predetermined category of subject matter. In order to create a category profile, a website is selected from the set (3), the website markup language is read (5), page content information extracted (7) and then analysed (9). The system may then check whether it has analysed a sufficient number of websites to allow for a reliable categorisation of subsequent websites (13). Individual websites are categorised by extracting their page content information (45) and categorising (51) on the basis of the degree of similarity between the information and the category profile (55). To control access, the system compares a website identifier with the database of categorised identifiers.
