Looking ahead to the the start of 2014 and beyond, Arora said that Google expected to count on three particular areas of growth to remain stable: performance marketing, banner sales and ad-tech platforms.
"Performance is a mainstay, thanks to increased search activity and the alignment of search and display strategies by marketers," he said. He also pointed to the branding possibilities of display, citing work with Kraft Foods on engagement metrics and a campaign that brought what Arora called an "impressive" 2.9% engagement, though he didn't elaborate much on what was behind that number.
"Our teams are working on the issue of cookies, and there are some early concepts that look promising," Arora said, much as he has on such calls over the past few quarters. "But it's too early to talk about what those precise solutions are going to be."
