Purpose This paper aims to examine how different levels of message appeals, message sources and social norms influence the purchase (i.e. booking) intention of eco-accommodations. Design/methodology/approach The proposed hypothesis was tested using a 2 (message appeal; rational vs emotional) × 2 (message source; expert vs blogger) × 2 (social norm; injunctive vs descriptive) between-subject experimental online design. Findings Advertising appeals and social norms are major predictors of eco-accommodation’s ad effectiveness and message appeals, sources and social norms, and their classifications interrelate with each other. The highest intention to purchase an eco-accommodation was found for a promotional message, which is sent by an expert, expresses a rational appeal and includes a descriptive social norm. Perceived emotional value in contrast was increased with a blogger statement including an emotional appeal and an injunctive social norm. Research limitations/implications The used experiment only focused on one product, namely, eco-friendly accommodations. The impacts of different message contents might vary as a function of the promoted product. Practical implications To develop persuasive messages which combine all three message contents, experts should craft messages with rational characteristics and address a descriptive social norm. Originality/value Although consumers show a desire to buy eco-friendly tourism products, it seems that supply actually overweighs demand. As research in the field of eco-accommodations is still limited, this study examines the role of different combined promotional message contents to further clarify the apparent gap in green consumption.
