I guess a lot of people who have monetized their blogs/sites with adsence don't have pretty much revenue... But instead of that, try using CPA offers, via banners on your site. Target offer, if you running dating site, use dating offer or something related. It can improve your earnings incredibly comparing to Adsense. You have a lot of variations with this and it has great potential. Grab some offer from CPA Network, test it and if it's not good try another one. Place offer wherever you want, on header, footer of your site..
