As a followup to this question, I'm setting up DFP for a blog and need to show one set of creatives to users from the US or UK, and just let AdSense fill in that ad unit when the user is coming from outside the US or UK.I've been playing with DFP and the interface isn't terribly difficult... I have already defined my ad units and uploaded creatives. (I also understand how to set placements to geotarget.) However, I'm not sure how to put the pieces together-- for example, I don't know exactly how to configure DFP to use adsense ads when the geotargeting doesn't match US/UK. Can someone give me a brief step-by-step answer to accomplish this goal?
How do I set up DFP to show one set of ads for US/UK and AdSense for everywhere else?

Set up your Inventory which is the spaces available on your site where you can show ads.  In each ad unit under inventory, there is configuration for adsense where you choose the colors and such.  If you have no Orders that match, adsense ads will show in that inventory.Setting up inventory and inserting the codes onto your website is all that you really need to do to use DFP.  Once this is done, your site will be showing adsense ads through DFP.To show ads that you negotiate yourself, go to your Orders, set them up and target the orders the way that you want them.  The most important setting is the order type.  If you want the order to always show up if the targeting matches, you need to set the type to sponsorship.  Otherwise the order will compete with adsense on a cpc basis.
