And here's a link to the related NYT article: http://www.nytimes.com/2010/02/13/technology/internet/13cupi...
That article includes customer acquisition metrics related to the blog's most recent post: http://blog.okcupid.com/index.php/2010/01/20/the-4-big-myths....
That blog post has received 750,000 visitors in the three weeks since it's been published. Those visitors resulted in 10,000 new members. That's about 34,000 visitors and 450 conversions per day and the overall conversion rate was 1.33%.
If OkCupid had to buy that much traffic and conversions through a CPC program they'd pay tens of thousands of dollars (or more). At $0.10 per click they would pay $75,000 for 750,000 visitors, at a more realistic $0.20+, they'd pay $150,000+. At a 1% conversion rate that would be $10-$20 per new member, or $100,000 to $200,000 total for 10,000 new members. Sensitivity test the variables up or down, but this shows the blog value-creation potential. Nice work, guys!
