Adperium Banner Advertising

I stumbled across Adperium.com, they host banners on LOTS of websites, i havent really dabbled in banner advertising before but would like to get my feet wet, can anyone offer any advice?

I was thinking perhaps a free credit score offer (completely free, no CC) pays only $3 but with not needing a CC it'll convert better…

Any nudges in the right direction? I tried advertising my initial WH site through adwords 8 months ago, but soon saw the light and used it to get into CPA networks…
