Comscore Rankings by number of sessions per visitor a month.
Plentyoffish comes in at 39 In the USA and the most visited dating site and 3rd after social networks.
Plentyoffish destroys all other dating sites when it comes to engagement but its very misleading. Plentyoffish doesn’t advertise much so we don’t get tens of millions of “uniques”. Remember the visits per user per month = Total visits/uniques. Sites like singlesnet and match.com may do a million popups plus a month and that totally kills their “engagement” metrics. The entire list is made up of games sites, users homepages, and sites that don’t advertise.
