please i want to know which is the best : according to rates, safety and all pros please ; Because i launch A network , and i am want to find these person who distribute and gain more knowledge : thanks
I don't think we could say that any particular model is the "most" profitable.
There are pros an cons to any of them and some are specific to certain offer types.
For example mobile apps are usually using the CPI (cost per install) or PPI (pay per install) which is beasically the same I believe.
CPA is used more on the traffic network side, so you set a CPA you're willing to accept and the network tries to optimize for it.
In you example, there seem to be two conversion models used, one is likely a clean install from some app store, the other one is about a zip file that needs to be unpacked and executed... this is a bit different from the payout models.
I'm a bit confused about your questions, what exactly are you trying to figure out? What payout model to use, or what conversion flow to use... ?
CPI/PPI is both the same model - you get paid per install.
And when we compare CPI/PPI with CPA then it depends what is better.
Mostly CPI works better because it´s a much easier flow: Install -> Conversion.
On CPA the user has to install the software and then he has to make a sale for the conversion.
CPA can work good but then you need a real strong funnel, in most cases CPI is better.
One more thing, we're playing with words here pretty much.
PPI means pay per install, CPI means cost per install... so it's basically the same, just from a different perspective.
CPA should be cost per action, but it's sometimes also used as cost per acquisition ... which can mean the same thing again, or not, given what the desired action is.
It's still just a model that defines what the advertiser pays for and it's really hard to say what model is better or easier as it depends on a lot of factors.
thanks for beautiful replies . the second Option that i Consider PPI actually a adware(Installers) for me > so in my network 5 million per month traffic is like a premium software and there patches , so for this traffic i need a best market adwares (installers with download direct in image ) . so i compare the result :
I know all the metrics , About companions , Funnel , target :
But here I try the clickdealer.com but not reached to target amount , because conversations are so less 1000 unique click in 5 Conversation : this was one side
SO the second side the need from here , i need a adware/spyware that direct installer from my lander . So that why the conversation are 1000 unique click in 250 to 500 Conversation :
i give you a example
here is a site that i want the offer
