Online dating is becoming more and more common among younger people as well as older adults. There are many different websites that people interested in online dating can use or subscribe to nowadays. There are also many dating services that aim at a large part of the population and try to distinguish themselves by means of the particular matching services they offer or by the number of potential partners people have access to through their site. Throughout most of human history, until very recently, one's choice of dates was restrained by geography. In addition, there are biological approaches that can be used as a complement to dating websites and are often integrated into these sites. Often people move their conversations off the dating website relatively quickly and converse by e-mail or phone to get to know each other better.
