In the internet dating space, bigger is not always best. According to the latest U.S. numbers from Hitwise, the top niche dating sites are steadily gaining market share while their big mainstream counterparts stagnate. We compared the overall dating market share of the top 5 sites - Singlesnet, Plentyoffish, TRUE, Yahoo Personals and Match - to the market share of several top niche sites to see how their growth rates compared. In March 2008, the top 5 overall sites held 7% less market share than they did one year ago (Plentyoffish and Singlesnet were the only sites to buck this trend individually). Meanwhile, the top sites from the top five major niche dating categories made considerable gains, with the gay dating and religious dating categories growing the fastest.
