Well you gotta spend a lot of money with PPV, because you need
to gather some data first and spending a lot of money at your campaigns.
From there you seed-out the non converting keywords/targets and starts
optimize your campaign until it's achieve reasonable profits.
So I'll definitely didn't recommend you try PPV if you got limited budget
to test out with. It's totally based on my experiences and opinion.
But still, I'm gonna answer your question:
Leadimpact is the decent one with least amount to deposit with.
There's cheaper solution regarding ppv, but can't assure you regarding
the quality of their traffic:
- Media Traffic
- Direct CPV
- Adoori
- CPV Interactive
