Spanish agri-food producers, particularly organic producers, have faced commercial problems for years. Websites are able to combine informative, relational and transactional functions. This ability makes them attractive sales channels in sectors such as the organic agri-food sector, which has traditionally had major commercial shortcomings in these three areas. This study is built on this premise. The study explored whether organic agri-food producers and conventional producers differ in terms of their use of websites as a sales channel and their degree of interaction with users. The extended model of Internet commerce adoption (eMICA) and fuzzy-set qualitative comparative analysis (fsQCA) were used. Other statistical techniques were also used. The fieldwork began with a sample of 998 producers (239 organic and 759 conventional). The results reveal differences between organic and conventional olive oil producers regarding website adoption and use. In terms of attracting website visits, the results also reveal the relevance of being an organic producer and having a capitalist or cooperative company structure.
