Google Chief Business Officer Omid Kordestani has confirmed what many already expected: Google will soon be adding a "Buy" button to its search results, giving users more reason to use the mobile version of the search giant while also creating a feature that will compete directly with rival Amazon.

"There is going to be a "Buy" button; it is actually Mover Over Amazon: A Google "Buy" Button Is Definite," Kordestani said May 27 at Re/code's Code Conference in Rancho Palos Verdes, California.

Kordestani did not go into detail about the upcoming feature, but in a report earlier this month, the Wall Street Journal said the "Buy" button will appear alongside product advertisements for search queries made on the mobile version of Google.

The Mountain View, California, tech giant will reportedly not take a cut of any purchases, giving the full revenue to retailers, who will be the ones to actually store inventory and ship items. For Google, the incentive is to draw more mobile users and make it as simple and quick as possible for them to finish purchases on their phones.

Though the "Buy" button will be convenient for consumers, it increases the tension between Google and retailers, many of which are among the company's top advertisers. That includes Amazon, which topped Google's list of advertisers in 2013 by spending nearly $158 million in search ads, according to a study by Ad Age and AdGooroo.
