I'd like to place ads on my site. I run multiple websites, my main one has visitors on a daily baises and i think ads will help with the funding of the sites.

I've signed up with google adsense. although i've heard they do not offer as much as some other ads.

Do you know of any ads which offer the most or affiliates? or simply any suggestions. I'm happy for some feedback as i've never done anything like this before.
