Again, not a regular banner exchange. A regular banner exchange program. A regular banner exchange program. You can target who gets to see your banner and you have some ability to block sites so they can't be seen on your site. I have had fair success with this one.
Some conditions apply.
This one you cannot target, so though you may get exposures your return for click throughs to your site can be very low. As the name implies. Two more banner programs can be found at the bottom of my main page. Both have been fairly successful. Working with the click thru program helps multiply the effect.
