Online matrimony websites have become very popular in India, growing at a rate of 30% annually. They provide a global reach for matchmaking and make the process more convenient and self-directed compared to traditional methods. Major online matrimony sites in India include Shaadi.com, BharatMatrimony.com, and Jeevansathi.com, which have millions of members and generate revenue through subscriptions and advertisements. However, these sites also face some challenges regarding user privacy, security, and the potential for fraud or misrepresentation.
