influencer media sosial sekarang memainkan peran penting dalam pemasaran dengan memperkenalkan produk kepada pengikut mereka. Salah satu influencer terbesar di dunia adalah Blackpink. Blackpink adalah selebritas dan influencer terkemuka dengan nilai pemasaran yang sangat baik, dan banyak dari produk mereka sering terjual habis. Tapi apa yang mendorong penggemar Blackpink untuk membeli produk yang didukung? Tujuan dari penelitian ini adalah untuk melihat pengaruh kredibilitas dan interaksi para-sosial terhadap niat beli konsumen. Lebih tepatnya, meneliti bagaimana para-social interaction (PSI) konsumen dengan Blackpink, serta credibility, terkait dengan purchase intention, dan bagaimana hubungannya dengan physical attractiveness, attitude homophily, dan social attractiveness. Oleh karena itu diharapkan penelitian ini akan membantu manajer untuk mempromosikan produknya dan selebriti untuk mempromosikan produk tersebut. Studi ini melibatkan 138 partisipan dan dianalisis menggunakan Partial Least Squares - Structural Equation Modeling (PLS - SEM). Menurut penelitian ini, credibility dan para-social interaction berhubungan positif dengan purchase intention pengikut. Selain itu attitude homophily, dan social attractiveness berhubungan positif dengan para-social interaction namun physical attractiveness tidak berhubungan positif dengan para-social interaction, sedangkan physical attractiveness dan attitude homophily keduanya berhubungan positif dengan credibility.
