O.k, so they say for PPC testing a campaign with 400 clicks is good.
Thats for PPC. How many views should you test per campaign with PPV
before you call it a wrap and move on to your next campaign? (Compared to 400 clicks with PPC)

Thanks in advance.

How many page views should you buy per campaign on average,
especially the campaigns they don't have a signification return on investment.
the basic idea would be nice.

The way I do it is by testing based on 10bucks (or whatever small
amount you are comfortable with).

If it makes profit, even by 1cent, I would improve on it and scale up.

For higher payout offers (>$15), I would double my adspend based
on the payout amount ($15 payout=$30 adspend).

Usually I do email marketing for higher payout and thus will pause the
campaign and see if it makes profit after 2 weeks... if it does, then I
will continue running it without pausing while still keeping an eye on ROI.

If I scale up on higher payout offers, the new ppv urls will also go
through the same pausing technique. Setting up your tracking efficiently
will help eliminate confusion.

Cheers!
