A new study by Performics (paid search marketing specialists) shows that mobile paid search impressions accounted for 10.2% of all paid search impressions (desktop and mobile) for Performics' client base in Q1 2011. It's the first time 10 percent has been reached, and marks an impressive 195% increase in mobile impression volume.
Mobile clicks are rising, too. In Q1, mobile click share accounted 9.8% of all paid search clicks, for an overall increase of 230% -- compared to clicks from computers which rose 13.7%
While this is just one study, the hard evidence points to mobile paid search as an increasingly important part of marketers' strategies. And while the volume of mobile paid search rises, mobile cost-per-click (CPC) remains well below that of desktop CPC. In March, mobile CPCs were 42.1% lower.
