Currently, the largest online dating sites are advertised on television, in magazines, and online. Most people can't escape promotions for these sites. Yet, the truth is, the most popular sites are not necessarily the best. If you are a young adult, chances are a popular site will be a great way to meet a match. However, older and religious individuals are typically more successful at specialty sites. Before trying online dating, figure out what you are looking for and determine which site is best for you.
