Banner Advertising

[GBN]

Hello everybody!
There is a problem, that is really matters for almost every Arcade webmaster, who face the choice between banner advertising and traffic exchange. As the site owner I should admit that traffic exchanges bring a lot of traffic to the site especially in it's launch period. And it's free. They give free bonuses, which can guarantee a good startup of your project.They advertise you on a number of sites, related to yours, which can guarantee traffic targeting.
There are only four things about this issue: the quality of traffic sent by the exchange, their service, the number of sites in this network and usability / flexibility of the system. These factors can influence my choice. Still I try every network to find one that suits me better. And only in case no one can give me good traffic I trade my 100x100 banners.


What do you do with your 100x100 ad spots?
In case you sell them, then to whom and what's the average price?

Thanks in advance.
