Should we use DFP? We have an older international real estate advice site with 700,000 monthly uniques. The site is large, with a hand-coded content management system into which we place ad codes depending on where we want the ads (position on page, section of site, runtime / number of impressions sold). We are just switching to Laravel and going responsive.

At present we run almost no directly-sold campaigns, just Ad-Sense, Medianet, and some Criteo. Not much daisy-chaining, mostly just different positions.

Should I ask my developer to learn and try DFP? He may not see the logic. Should I insist?
