New in Plugrush. Need help!

I just started using Plugrush on my adult site.
My site do not have to much users, so I created ads as a publisher and put to my website. Also I created campaign as a advertiser and I spend $10 for it. I get around 1500 users to my site from it, but I earn just $0.75!!!! it was not what I expected at all. I am working with adsense on my other site, so I am earning around $10-20 from 1000 visitors.
So what I did wrong? I didn't expected to earn like from adsense, but 75 cents from 1500 users it is not normal I think.
I put and some JuicyAds banners in my site too, I get around 40 clicks from Plugruch campaign and earned 2 cents. It looks strange too for me...???
What is my mistakes there? if you need to see my website it is on my signature.

Wellcome to adult niche!

But any way, any advice...?

make plugs, set ads to trade traffic

hmm it is interesting in short time I have reached about 20 users per day and I am making about $0.05 per day
any ideas how to reach 1000 users per day?
