But with so many sites catering to very different tastes, which is the right one for you?
Naturally, I should be steering you towards Telegraph Dating, which I'm contractually obliged to tell you is BRILLIANT.
e Harmony takes a quantitive approach to matching based on “key dimensions of compatibility proven to be the foundation for a long-term relationship, like character, intellect and values”.
For those looking for a long-term emotional investment the site is very good at separating the wheat from the chaff and finding the sort of people you say you like, but it means that you may miss out on the spark of someone surprising and exciting enough to tempt you away from your usual "type".
(uk) Ok Cupid Ok Cupid describes itself as "the fastest-growing online dating site", thanks to its "math-based matching system" - dating's answer to Google's algorithm. More important than what's going on under the bonnet, the standard of hotties on the site is relatively good, with plenty of hip, urban types on its database.
(see below) it aint - in my experience many people here only want a FWB arrangement, so don't sign up looking for a life partner.
But if that's your cup of tea, great, and I'd certainly recommend it for its in-depth filtering system, a series of questionaires that narrow down your search in a realistic and practical way.
(okcupid.com) Match This is where people go to get married, if you believe the ads, and you have to be pretty serious if you're going to stump up the £30 monthly fee (cheaper if you commit to three or six months).
I didn't get married after my experiences with Match, but I did learn an important lesson: an awful lot of people are deceptively attractive from a distance.
One fella I dated for a few weeks seemed to have it all going on; he had a briefcase and a job which occassionally requred him to commute to Burgess Hill, so I was pretty sure that he was a full-blown adult.
I heard wedding bells after the first few dates, until he started acting like we had already been married for 17 years and gave up on any pretence of romance.
