How does eHarmony's matching algorithm work?

eHarmony's matching algorithm is a sophisticated process that focuses on compatibility and long-term relationships. It uses a scientifically-developed Compatibility Matching System (CMS) that analyzes key dimensions of personality and preferences. The algorithm considers data collected from in-depth questionnaires completed by members, including values, beliefs, personal habits, and relationship goals. It then compares these characteristics with thousands of other profiles to find potential matches. The CMS also considers factors such as emotional temperament, social style, and communication style. This comprehensive analysis allows the algorithm to provide highly compatible matches by focusing on compatibility at a deep level beyond just superficial attributes. With continuous research and updates, eHarmony's matching algorithm continually improves to ensure users have the best chance of finding a meaningful, long-lasting connection.
