NEW YORK -- " Facebook is testing a "Buy" button in its latest effort to help businesses boost their sales through the world's biggest online social network.
The company said in a statement Thursday that the button will let people buy products directly from businesses without leaving Facebook. A "Buy" button appears at the bottom of sponsored ads and is being tested by a limited group of several small- and medium-sized U.S. businesses.
The move comes as Facebook continues to grow its advertising business. The company will account for 7.8 percent of global digital ad spending this year, up from 5.8 percent in 2013, according to eMarketer. Google, the world's No. 1 recipient of ad dollars, is expected to account for 31.5 percent of ad spending in 2014.
