Small world theory and the World Wide Web: linking small world properties and website centrality

This qualitative paper aims to point out the incidence of small worl characteristics in the World Wide Web. To this end, some theoretical implications of small world theory (SWT) are verified using information from focus groups and in-depth interviews administered to experts and users of the World Wide Web. The purpose of this study is to investigate whether it is possible to apply small world properties to online social networks while pointing out the key variables of website centrality in that context. Building on this, the paper traces possible contributions for better management of the World Wide Web in terms of the professional use of social media to facilitate information or product and service sharing. The results of the proposed investigation highlight some pivotal aspects of small world properties on the web, as well as on website centrality. The findings are relevant for the application of social media marketing (SMM) and search engine optimisation (SEO).
