Jaren Vitale: Great question. Waiting for answers with you. Thx.
Dave Elliott: No, because not everyone who runs a traditional ppc campaign has a physical product to sell on their site. ;That and of course PLA's are PPC!
Matt Raynes: So you don't maybe see how PPC ads may change, become more visual perhaps or PLAs combine with PPC ads in other ways regarding metric measurements relating to a quality score? ; I kinda know they'll not replace them entirely but could a comprise occur that may affect serp layout?
Dave Elliott: pla's are already quality scored aren't they? I doubt normal ppc adds will become more visual without the organic results also becoming a lot more visul, who knows they maybe with open graph type stuff, it will happen, but it will start looking very cluttered if there is a logo/image next to every result!
