Based on the increasing competition in the e-commerce industry in Indonesia, taglines play a crucial role as verbal communication elements in shaping brand image. The tagline "Buy Everything at Shopee" was chosen due to its consistency from 2017 to 2023 and its ability to reflect Shopee as a one-stop shopping platform. This study aims to explore the semiotic meaning of the tagline by applying Roland Barthes' theory (denotation, connotation, and myth) and examine its contribution to building Shopee's branding. The research method used was descriptive qualitative analysis using semiotic analysis techniques, while data sources were obtained from documentation of various Shopee promotional materials, theoretical literature, and industry reports. The results show that denotatively, this tagline implies an invitation to shop at Shopee; connotatively, it reflects ease, completeness, and efficiency; and at the myth level, it builds Shopee's image as the premier digital shopping solution. From a branding perspective, the tagline reinforces a friendly and modern brand personality, a brand promise of easy, one-stop shopping, and an emotional attachment with consumers. This study concludes that the tagline "Buy Everything on Shopee" is not simply a promotional phrase, but rather a strategic element in strengthening Shopee's brand identity amidst e-commerce competition. The recommendation is for Shopee to maintain tagline consistency in its communication campaigns, while continually adapting its narrative to digital trends and consumer needs. For further research, a comparative study with other e-commerce taglines (Tokopedia, Lazada, Blibli) or exploration of other verbal branding aspects such as slogans and jingles is recommended.
