These results highlight the strategic importance of branding and personalized communication within the e-commerce ecosystem. Furthermore, the study demonstrates that digital communication factors—such as interactivity, user engagement intensity, and information accuracy—play a crucial role in strengthening consumer loyalty among Generation Z. The study contributes to the growing literature on digital marketing communication by emphasizing the effectiveness of personalized advertising strategies in fostering long-term customer relationships in the digital era. Fungsi internet kini telah bergeser jauh melampaui sekadar sarana komunikasi; ia telah bermetamorfosis menjadi arena transaksi utama yang secara dominan membentuk dan mendikte gaya hidup kaum muda. Studi ini difokuskan untuk menginvestigasi dampak dari personalisasi iklan serta citra merek terhadap tingkat kesetiaan konsumen, secara spesifik pada kalangan mahasiswa Gen Z di lingkungan Universitas Tarumanagara. Landasan konseptual yang digunakan berpusat pada teori-teori mengenai kustomisasi iklan, persepsi merek, dan loyalitas konsumen.
