Here are examples of the kind of traffic you can buy at an Ad Network:
RON – ROTATION ON NETWORK
This is a campaign in which your ads rotate on a network of sites; spots that are part of a packaged deal and can’t be sold separately. This traffic typically consists of different sources (websites, blogs, forums, etc…) and this in turn, creates the RON.
Remnant traffic is traffic at a discount. Essentially, it’s the leftovers; it’s traffic the biggest media buyers in the game couldn’t do much with… and that is why it’s sold at such bargain prices.
But you know the saying, the leftovers of others make a feast for some!
The harder-to-convert traffic of industry players may actually be to your benefit if you have a decent geo-targeting strategy.
