If you have a site with purchsed content ( Dont use this with sponsor content) This is a pretty good way to make money from it without having the surfer pay any money what so ever
It is a widget that is put into your site which locks your content up and makes the surfer fill out a free survey which will only take 1 -5 min . When they complete the survey it gives them access to your content for however long you specify and you get paid for it. This is being used on mainstream and is working very well and now the adult version has come out. You can have the widget set to tease so that it only locks up the content after any specified time. The widgets are very easy to implement and are very customisable.
Its like billing your surfer whithout them having to pull out a credit card or pay a penny
