Today we are announcing a unified approach to digital advertising that only Yahoo can deliver – across premium and audience-focused display, native and search advertising.

The online advertising world today is fragmented, difficult to navigate, and not always customer-friendly. For advertisers to get the reach, targeting, and ad effectiveness they want, they have to work with multiple publishers, ad networks and exchanges, demand-side platforms, and analytics vendors, among others. And still, advertisers are left with limited ability to measure and optimize the performance of their campaigns.
