Facebook Accounts For 17% Of Mobile Ad Revenue in U.S.

Facebook mobile ad spendingWe recently looked at mobile ad spending in the UK; in the US, spending on mobile ads is also increasing rapidly, approaching $9.6 billion in 2013.  Thanks largely to growth in mobile ad revenue, Facebook became a major player in the digital ad space this year; the social network is now the 2nd largest digital ad seller in the US (with $3.17 billion), behind only Google (with $17 billion). Twitter is responsible for just $420 million of US digital ad revenue, or 1% of total digital ad spending.

Facebook’s second place finish marks a revision in eMarketer‘s forecast; originally Yahoo! was predicted to hold the 2nd place slot in terms of digital ad revenue. What fueled the switch? In 2012 Facebook’s share of mobile ad revenues in the U.S. was 9%; in 2013, that number jumped to nearly 17%.

The rise in mobile ad spending (as a percentage of total digital ad dollars spent) has been staggering. Back in 2010, mobile ad spending accounted for only 3% of digital budgets.  This grew to 12% in 2012, and this year mobile ad spending accounts for over one-fifth (22.5%) of all digital ad spending in the U.S.

How does this compare to global numbers? Mobile ad spending accounts for 15% of all digital ad spending worldwide, up from 8.5% last year.
