In the second quarter Facebook continued its trend of growing mobile ad revenue to a larger share of its total advertising revenue. Although this result is in line with our conclusions based on Facebook’s performance in the first quarter, the significant beat on estimates has resulted in the stock price rising to pre-IPO levels. In order to understand how Facebook has continued to grow mobile ad revenue, we need to reassess its advertising business.
We determined that in the first quarter increases in advertisements delivered and price paid per ad resulted primarily from News Feed ads on Facebook’s desktop product, and to a lesser extent on its mobile products. We also observed increases in user engagement in the quarter. Finally, Facebook’s decision to lower the market reserve price increased market supply for ads on the network essentially by reducing the input costs for advertisers.
Revenue in the second quarter remains highest in North America and Europe; however, the growth in Facebook’s emerging market regions continues to outpace the established markets. The North America region saw $721 million in revenue, an increase of 51% over the year ago quarter. Europe region’s revenue grew from $294 to $479 million, a 53% year-over-year increase. In Asia and rest of world revenue essentially doubled over the year ago quarter.1
