Google’s Mobile Search Revenue To Top 30 Percent, Desktop To Fall To 43 Percent By 2015 [Forecast]

In its latest look at mobile ad revenues, eMarketer estimates Google is generating nearly one-fifth of its US advertising revenues from mobile search, coming in at 19.1%.

In yet another indication of how fast the mobile ad market is growing, only two years ago mobile made up just 4.8 percent of Google’s US ad revenues. By 2015 mobile is expected to account for just over 30 percent of Google’s ad revenues in the US. Desktop search revenue share is predicted to fall below 50 percent in that time.

Google AdWords enhanced campaigns, which went into full effect in July, lump tablet and desktop bidding together so all desktop campaigns automatically include tablet bidding. eMarketer has not indicated whether enhanced campaigns are contributing to Google’s projected mobile revenue increases.

While Google’s mobile display revenue share is expected to grow at a faster rate than mobile search (147 percent vs. 61 percent) by 2015, mobile search will continue to dominate Google’s share of mobile ad revenues. YouTube is the main driver for the increase in Google’s mobile display revenue according to eMarketer.

Overall 22.9 percent of Google’s US ad revenues will come from mobile channels.
