Online marketing has become one of the most critical tasks in business management in recent years. The application of online marketing in various industries has flourished and increased in sophistication, causing online marketing to become an effective method of trading worldwide, as well as a crucial development trend for Taiwanese agriculture. The Sinyi Township Farmers' Association (STFA) has successfully employed online marketing. In this study, we analyzed the online-marketing business strategy of the STFA within a 7P (Product, Price, Place, Promotion, Participant, Physical Evidence, & Process Management) framework, the results of which can serve as a reference for promoting the online marketing of Taiwanese agriculture. Despite numerous restrictions, the STFA has fully integrated local agricultural efforts and ethnic culture, considered the consumer perspective, disregarded traditional practices, constructed a successful brand image, created a consumer-based image, and established an excellent reputation on the Internet.
