I came across this term, and I'm not sure what it means. If anyone can help me out, I'd be grateful. Thanks
why don't you use google search? that's what its for http://www.google.ca/search?hl=en&q=what+is+Direct+Advertising+Feed&aq=f&aqi=&aql=&oq=&gs_rfai=
Actually I should have been more specific. I overhead someone referring to a "direct advertising feed" from Google or Yahoo. This isn't described on the adsense website or on yahoo, and there don't seem to be relevant search results.
