Executives at Google’s Retail Leadership Summit 2015 discussed the company’s initiatives for building a more frictionless smartphone shopping experience, including rolling out mobile voice search for shopping and a buy button implemented within advertisements. In the past year, Google has seen a 115 percent uptick in shopping searches stemming from smartphones around the world, cementing the mobile device’s role as a primary shopping tool. The company’s focus on offering users specific answers to product inquiries, as well as streamlined checkout options, may prompt more retailers to join forces with it and allocate more of their advertising budgets to mobile search.
