Abstract: Background: The United States (U.S.) faces a significant mental health crisis, with around 52.9 million adults experiencing mental health disorders, with young adults (18–25 years old), such as college students, having the highest prevalence and lowest service utilization rates. While efforts to expand mental health services through “push” strategies are in place (e.g., training therapists in evidence-based therapies), limited initial engagement suggests a need for “pull strategies” and targeted marketing that make services attractive to college students and increase demand. This mixed-methods study identifies U.S. university mental health clinic websites and website characteristics that are attractive and engaging to college students interested in seeking mental health services (i.e., students were considering or actively looking for mental health support). Methods: Eleven U.S. university websites were chosen (10 randomly and one from the university where students were attending) from a pool of 44 Psychological Clinical Science Accreditation System training clinics websites. Fifty-seven college students (Mage = 20.95, SD = 2.97; 81% female; 68% racial/ethnic minority) were videorecorded engaging with two U.S. university mental health clinic websites, completed self-report engagement measures, and gave detailed feedback about websites through semi-structured interviews. Results: Likert scale scores revealed moderate engagement with all websites (e.g., they were interesting and helpful). Qualitative results indicated that websites that provided important and easily understood information about key features of services (e.g., types, evidence-base, and cost), therapist backgrounds, psychoeducation, used lay language, and had an appealing website layout (e.g., color, font, images, organization, and interactive components) generated greater consumer interest and trust in their mental health services. Conclusions: This study emphasizes the importance of using marketing strategies to enhance college students’ engagement through mental health service websites. Salient features, psychoeducation, and effective promotional strategies (e.g., how information is presented) were identified as crucial for website engagement and subsequent mental health service uptake. Using marketing strategies, such as tailoring language to consumer literacy levels, describing the evidence-base of services, and improving website design may address college students’ needs and enhance initial mental health service engagement.
