Sephora is a major cosmetics retailer focusing on digital marketing to build a strong brand image and boost online sales, targeting primarily women under 34 years old and men aged 20-40. It faces competition from both high-end department stores and independent beauty suppliers, emphasizing a distinct digital presence through engagements with influencers and social media platforms. Sephora's website optimization and user-friendly checkout process contribute to its online success, although enhancing content across various social media could improve engagement and attract a broader audience.
