How do you inject ads into your websites?

I'm curious how you guys are injecting ads on your pages. Are you doing it manually, using software like WP plugins or something else? I'm currently using AmpedSense for WordPress to handle the injection, works great for me, aside from some minor bugs here and there.

If you're injecting by hard-coding ads, how do you run split tests?

I use AdRotate for some placements and just include them with a WP function in others.

Back before I moved to WP, I used to run split tests with a little PHP script that rotated ads (as included files) in even rotation. Crude, but effective.
