eHarmony was launched in the UK in July 2008, as an alternative online dating site for singles looking for a long-term relationship. In the USA eHarmony.com has developed into the most trusted relationship website.

As they proudly announce, eHarmony.com is responsible for nearly 5% of all new U.S. marriages.

eHarmony’s Compatibility Matching System is based on a rigorous scientific approach to relationships and they have developed models of compatibility particularly adapted for the British resident population.

eHarmony.co.uk matches you with like-minded singles based on key dimensions of compatibility, such as humour, intelligence and passion.

There's a quite long and detailed questionnaire to fill out in order for the system to work well, but the benefits can be tremendous!

Another important aspect about eHarmony, is that you can’t search profiles. They’ll rather send you compatible matches (as they say, „eHarmony: a relationship site, not a dating site“)

Created in 2005, MatchAffinity.com is an online dating agency run by Match.com, which is part of Meetic in Europe. It’s dedicated to matchmaking and offers the classic functions of online dating agencies.

MatchAffinity.com provides a service based on a unique psychometric test designed to bring together members who share a common purpose: building a strong and lasting relationship.

Using the free Affinity Test you can find out which users are most likely to start a stable relationship with you. The detailed questionnaire of this dating agency takes about 30 minutes, but this time is well spent because the system quickly shows the results of the test!

The high language level of profiles like a well-educated public.

Be2 was founded in Germany in March 2004 and expanded to the UK in 2007, where it has developed into one of the biggest online dating agencies. Today, be2.com has about 26 million members and is represented in 34 countries.

Be2.co.uk operates on the basis of a scientific model of analysis using psychological, anthropological and sociological criteria to assess the compatibility of two personalities. Depending on your test results, be2 suggests you various candidates who are well suited to you.

The personality test is quite detailed containing about 60 questions. You will probably need more or less 15 minutes to fill out the form.

The second part of the test concerns your interests, your ideal partner etc. You will need another 20 minutes to finish the test.

In a nutshell: lots of members, cheap short term membership, but ... watch out with the payment renewals!!!
