Hey VenusBlogger: There is no secret behind it - I will sum it up for German traffic and give a little example:
1) You have your own landingpage that refers to your own or one of your sponsor partner's dating product
2) You offer a registration form in the public area on your landing page or after clicking through free content (cam, pics or whatever suits your main traffic best)
3) You use a Country field within the registration form
4) You send all Germany, Austria and Switzerland signups to the API with the pre-integrated script offered by Partnercash or other partners - You can get the documentation about it once you contact me (see my signature)
5) The generated signups for mentioned countries are provided to the API and they will be offered an activation link for German dating product
6) Once activated (double-opt-in) the User now has an account at e.g.
http://www.sexkiste.com and can use the provided content (obviousely not for free)
7) Each generated Lead (like described) will be paid out after activation with a price of 2,10? each (prices vary by products).
8 - 10) Invest your earned money the right way
To see the full documentation just ask for it! There won't be any secred!
