More and more questions showed up about starting with Google DFP. If you've an Adsense account you can use DFP, look at www.google.com/dfp DFP is an adserver of Google.
DFP has several benefits like managing your ads. If you've not much traffic I don't see much benefits of using it. If you've affiliates you want to combine with Adsense it's easy to setup. Direct advertisers or in house ads are also possible to combine with Adsense.
I'm using it with header bidding, affiliates, in house banners and Adsense.
Any questions about setting up or related subjects can shared here.
