I'm new. I was signing up as an advertiser on the ad network buysellads.com and came across this: "Install and use BSA’s ad serving code on your website at all times that you publish or sell ads through the Site;" I was wondering, when a publisher installs ad serving code for a particular network, is that publisher now tied exclusively to that that ad platform?
No, you can use other ad platforms too. You can even use Google Adsense while using BSA. I am using BSA on my site www.inspirefusion.com, I don't use any other ad network but if I want to I can easily use them.
