According to Zanox Marketing Platform, Leads to Online Dating Sites are highest between the working hours, 7:00 am to 5:00 pm.

The highest CTR (Click Through Rate) occurs at lunch time between 11:00 am and 2:00 pm and at the end of the day after work between 4:00 pm and 6:00 pm.

Zanox’s Research also shows that there is a Seasonality Effect : 

Cold weather, Low Temperature (Autumn, Winter) means high online dating traffic.

Nice weather, High Temperature (Spring, Summer) means low online dating traffic.

For example between August and September 2008, Zanox reports a traffic increase of 55%.

I think these numbers can be interesting for firms who want to developp online dating marketing strategies or even some seasonal websites, why not.
