Here are the top dating sites in the world, from latest Comscore July 2009 report. The most interesting trend over the last year is the growing difference between usage at paid sites verses free sites and hybrids like singlesnet.
We are doing super well in Canada even though we don’t have a french version of the site which is about 1/4th of the population. We dominate the english speaking part of the country. As you can see in august our user visited nearly 18 times a month compared to 4.2 at eharmony. And we have 16 times the number of pageviews as our closest competitor Eharmony.
It definately looks like the US(chart not shown) is trending free like Canada, If you combine total visits at Singlesnet and Plentyoffish in the US, our 2 sites combined already have more monthly visits than all pure paid sites combined. I don’t think many paid sites are going to be able to maintain critical mass over the next year. It is sort of the same trend we are seeing in all english speaking countries.
