Private hospitals offer an alternative for those who sought services beyond what the public sector provided, often characterized by shorter wait times, more advanced facilities, and a wider range of services. The current study sought to investigate how digital marketing strategies affect performance of private hospitals in Nairobi City County. The study was anchored in the marketing mix theory. A sample of 96 employees was used. Data was collected using a selfadministered questionnaire and analyzed using descriptive and correlation analysis with the help of Statistical Package for the Social Sciences. Hospital performance was significantly positively correlated with digital marketing techniques (r = 0.578, p = 0.000). The study concluded that hospitals that regularly update their websites, actively engage on social media, and use digital tools to track patient interactions experience improved performance. Hospitals should therefore strengthen their digital marketing strategies by regularly updating their websites with relevant information on services, health tips, and promotions to enhance patient engagement.
