need help with Who sees Ads | Bloggers Lair | Yakezie Forums

In the continuing effort to clean up my site, I'm trying to remove some ads from showing up for regular readers. 

Can someone help me with the who sees ads plugin or recommend another good one? 

I have a media.net ad before post and I want to make this one show up only for SE readers for example. 

I set up who see ads and what's the next step? 

Normally, I use wp-insert to insert the ad before post. The who sees ads plugin doesn't seem to make any difference.

Do I need to insert the ad manually somehow? What am I missing?

Thanks in advance.
