Facebook is this summer giving advertisers better ad targeting data so they can find better-quality ad inventory, according to the social network’s ad chief.

“Adding people-based marketing, we’re taking the level of quality that markets can count on… understanding that they can deliver to real people,”  Facebook ad tech head David Jakubowski tells Beet.TV in this video interview.

“We’re beginning the first phases of bringing in data for marketers to be able to target just like they do on Facebook. Those things are happening this summer, we’re in our first test on that.”

2015 Q1 advertising revenue jumped 46% from a year ago to $3.32 billion, 73% of which came from mobile.

Facebook recently announced that LiveRail, its video ad server, would move to support mobile display ad sales, too.
