A thought:
3,811,600 USA Men 25+ Interested in Women/Single * average offer payout of 4.5$ =
$17,152,200
3,196,000 USA Women 25+ Interested in Men/Single * average offer payout of 5$ =
$15,980,000
That's a TOTAL USA potential market size of about 30 million, and thats assuming every single person can be converted.
What can I say, it's profitable for now, but is it sustainable? I assume ~1000 affiliates are doing it/attempting it.
That's a small ass fucking pie when you're sharing with that many.
Edit: yes there are international demos, but this one dwarfs the others put together.
Your theory is based on that all affiliates are pushing the same exact offer. As I'm sure you know, there are dozens of different dating offers being pushed on Facebook, and the same user may signup to several of them. Not to mention that everyday more people register on FB, become single, qualify under the single demo. A more realistic pie that we are sharing would be in the $xxx millions; but again, a new dating offer will just keep expanding it.
