Google to Unveil Buy Buttons in Mobile Search Results

Wall Street Journal: Google will launch buy buttons on its search-result pages in coming weeks, a controversial step by the company toward becoming an online marketplace rivaling those run by Amazon and eBay. The search giant is expected to start showing the buttons when people search for products on mobile devices. The buttons will accompany sponsored — or paid — search results, often displayed under a “Shop on Google” heading at the top of the page.
