Lots of ads are per-impression not per-click. Really that's the only sensible way to do a brand-building campaign.

Anyway, I have no problem clicking ads if they're relevant and for something I really want to learn more about. It's just that they rarely are.

I have only clicked an ad once in my life. I was searching Amazon but couldn't find anything suitable. Then I noticed they were showing me an ad from a 3rd-party site for exactly what I was looking for. I clicked it, and bought the product. So at this rate, ads help me out about once every 15 years.

You're not the internet. If nobody clicked on those ads, they certainly wouldn't exist.
