Just a heads up no one seems to be mentioning here - if you use a Locker, don't be 'that guy' and have every single video / link locked even after they complete the offer, everyone thinks doing this would be the surefire way to get fast $$ right? FALSE. lol but personally i would not use a locker AT ALL - it kills your traffic - and so much more $$ can be made, so why kill it. I say the only thing you should have poping up is from intro click pop ups & exit page popups - or else youll never get the user to stay / come back - tube sites are easy to pump and dump, i've built 3 of them & sold every one. of course that was 2 years ago, and I am by no means some 'guru' i just figured id say something so you can learn from my mistake ya know... just my 2 cents
