Google has recently loosened its AdSense Terms of Service so publishers can run other contextual targeted ads along with Google AdSense, but the change may be because Google wants to run their ads in publishing vehicles alongside other advertisements (like the ads running within Facebook).
Steve Rubel thinks that Google AdSense ads will soon be coming to the Facebook applications Google has been slowly rolling out, especially after the quote from Eric Schmidt in AdAge :
“How will those developers get paid for those services? We would like to have our ads in those applications.”
Would you like to see Google AdSense in Facebook Apps with the current FB applications publishing?
First you should have a face book application with hosting service.
Second you should have a google adsense account if you don't have one go to google and create one.
Create adsense ads that you want to embed in your FB application(s).
Put your adsense code in empty html page and add some keywords inside this page, this page will include your adsense script and some keywords to direct traffic.
embed the previous page in another page that includes the below frameset to disable scroll bar:
<frameset border="0" frameborder="0" framespacing="0" rows="100%,*">
<frame src="Google-code.htm" noresize scrolling="no">
embed this page in facebook using iframe.
< fb:iframe src=http://www.yourwebsite.info/fbads/google-frame.html id="fbad-header" name="fbads-header" marginwidth="10" marginheight="10" scrolling="no" frameborder="0" height="105" width="740" />
