PPI or CPA or...?

Hello guys

according to your experience what best way to take!.

youtube+CPA? or youtube+PPI ? and why?

and also please provide me the website network that you suggested me (CPA or PPI)

Thank You.

Youtube + CPA worked well for me, since for PPI, people need to take much more action, but for CPA, they will just sign up and i will get credited for the action they've taken. And moreover the conversion rate for CPA is more from youtube traffic when compared with PPI offers.

But its always to split test both and see for yourself.
