Generic sites usually have a wider variety of people so you're likely to find someone with similar likes and values as you. Generic sites are also more casual and versatile than niche sites. For example, Tinder uses a simple profile system and algorithm to connect users. Tinder users can easily swipe through profiles to find a match and start a conversation. Users looking for all kinds of relationships can benefit from this free dating app.
Joining a niche site means fewer profiles to sort through. Dating sites such as Farmers Only and Geek 2 Geek provide an online dating service for users with specific interests. If you have a unique interest, lifestyle, or hobby, joining a niche site might cater more toward what you are looking for, but there is no reason you can't sign up for both.
