Is this normal? Ad Statistics.. Users not engagings...
 

It seems my users are not interacting with the advertisements at all.

Here's a regular ad widget:

Slider ad:

Popunder Ads.(These are the only ads with decent statistics. And that's because users are forced to click these.)

What am I doing wrong here? I'm going to remove the slider ad. As it's just stupid to have it.
It has virtually no clicks.

I'm currently with plugrush, I might switch to JuicyAds and see how that goes.
