Instagram, followed by TikTok and Snapchat, was found to be the most dominant platform in the landscape of social media marketing, according to descriptive statistics. Regression analysis showed that the characteristics of Instagram, which focused on diversified product promotion, customer attraction, and better customer engagement and loyalty, greatly influenced sales performance. Snapchat, which places an emphasis on customer attraction, demonstrated a significant influence as well.
