The study finds that tablets are a growing part of the equation, too. Marin data shows that tablets held 31.6% share of all mobile clicks in July 2011, before growing to 37.9% by year-end, a 20% rise. Indeed, Marin analysis suggests that tablets will account for 45% share of all clicks by December 2012.
Mobile Share of Clicks More Than Doubles
The impact of mobile devices on search grew continuously throughout the year. While mobile devices accounted for just 5.3% of all clicks on Google in January, by December, they had climbed to 12.3% share, representing a 132% increase. At current rates, Marin estimates that mobile devices will account for one-quarter of all paid search clicks on Google by December of this year.
Indeed, mobile search will be the driving force behind 2012 search growth, according to February analysis from Performics. Looking at its retailer clients, Performics found that mobile paid search clicks continued to gain share in January, reaching 21.5% of all clicks, with tablets (39.6%) again a significant contributor. Considering the release of the iPad 3 and new Android tablets, the company predicts that mobile click share could rise to as much as 28% of all search clicks over the next 6 months.
Share of Spend Also Jumps
Data from Marin’s report indicates that ad budgets on mobile devices also saw a significant rise during the year. Beginning the year at 3.4% of advertiser search budgets, mobile devices had reached 8.7% of all advertiser spend by December 2011, a 156% increase. Marin forecasts this share to grow even faster this year, estimating mobile to account for 23% of paid search budgets on Google by December.
