Is there a formula or way to calculate the openx banner display portability
because i have some banner(campaign) are contact some are remnant and some of those has capping but some not
it seem the portability was quite hard to control
and i heard that openx will use old stat to calculate the priority of the banner too
so is there any formula to calculate it out?
Yes. there is formula
The easy way is to understand that first you got campaign, and then banner!
if campaign A weight is set to 50, campaign B to 10 and C to 40, this will be the delivery sheme.
