Our vision is ambitious: to fix Display campaigns. As anyone who has been running a serious PPC campaign knows, the Google Display network is broken. Partially through fraud, partially through negligence, partially because it's the nature of an arms' race with spammers.
We are using various methods to make your display campaigns work, and our first one is to focus on giving you the right, on-target placements to put your ads onto. That alone should eliminate the bottom 80% of spam sites that just suck up clicks without delivering human (much less targeted) traffic.
