Are you looking for any particular nitche? Othervise I have been using adbrite and really like it so far. I like how you choose who advertises on your page and for how much.
I say if you have good content google adsense is a pretty good service but with multimedia content like I have it cant make hardly any money. I myself am in search for a good revenue generator
i will give advertising for a dating site ( free ) i used adbrite and adenge now ( still using = looking for others.. any?
I see some of you are looking for a new way to sell your advertising space and I thought I should tell you about AdsBay, which allows you to auction off your advertising space free of charge to a global audience. Have a look at www.adsbay.co.uk
