Notes: Mobile will grow to represent 50.1% of digital search ad spending next year, predicts eMarketer, up from 38.1% share this year.

That tracks with the trajectory of mobile search traffic as tracked by RKG: it’s latest figures tabbed mobile’s share of organic search visits at 38% in Q3 2014, up 10 points year-over-year.
