Why would they not apply those better signals to existing display campaigns. Guess it's just trying to move people from search to search + display.
"So starting today and over the next few weeks, we'll be removing the current Search & Display Networks campaign type in the AdWords interface, and we're encouraging advertisers to switch existing campaigns to Search Network with Display Select."
Compared to the old campaign type, initial tests show that advertisers, on average, could see a 35% higher click-through-rate, and a 35% lower cost-per-customer purchase on the display portion of their Search Network with Display Select campaigns.
35%? Display Network performance is abysmal for me. It would take a 350% increase for me to try again.
