The ultimate question...

Do you prefer Adsense or YPN?

Adsense
http://www.google.com/adsense
Google's contextual ad netword, the most widely used [and abused] program

YPN
http://publisher.yahoo.com/
Yahoo PublishersNetwork

Use one? The Other? Both? Something different...

Share your comparisons and thoughts.

Yahoo Publisher's Network is known to generate more revenue than google adsense. Just look at some established sites, most uses YPN if they can.

However, YPN right now is in its Beta testing so its rather hard to get approved. Also, US sites only.

Use one? The Other? Both?

putting two advertisement on one site is against the TOS

Hi,

I have used YPN in the past and have found that it does pay higher than Google but with YPN only users in America can take part until it finishes with beta.

Go with YPN if you can
