Hello everybody. Sorry for the naive question but the posts that answered my question were old (2013 or earlier).
1) My question is: is it still possible to make $150/day in POF with dating sites with an optimized campaign? Or the competition is very high now and I'll get at most $10/day?
If the answer is yes, can I did that with few countries (South America)? Or need to scale to several ones?
2) POF just works for dating sites?
Thanks for any help guys.
PS.: sorry for english mistakes 
1) Of course! But it won't happen by magic - you will have to hustle, optimise and roll out campaigns to find out what works. There's no reason that a single campaign can't do $150/day but it will need to be quite broad I imagine, so if doing very niche campaigns you will likely need several.
You can surely do $150/day in one country but why limit yourself? If scaling to more countries gives you more profit then do it anyway, $150/day is a very arbitrary goal.
2) PoF is a dating site therefore most people there are interested in dating sites... Hence why dating works so well - the demographic is surely interested. People have made other things work but you have to remember why the users are there... But like all humans, they are after health, wealth and entertainment so can be sold anything with the right angle.
Really thanks Zeno. You raised excellent points.
I'm studing the forum a lot since I'm relative new to AM. I have done some facebook experiments since last year, but was not so successful.
I come from seo+adsense niche blogs (2k month). Sites are still monetizing but I'm tired of getting slaps from pandas, penguims and others animals.
So, really thanks Zeno, i'll start my tests in POF then (CPVLab in already up).
