This paper studies the communication of the corporate social responsibility (CSR) behaviour of 1054 Italian small and medium-sized enterprises (SMEs).

At the same time, the empirical analysis shows that companies in controversial industries have a lower probability of having a website. This raises issues regarding the propensity of controversial firms to set up a website, since it could expose them to public scrutiny and criticism
