A new study released recently by Juniper Research has predicted that revenues generated by mobile search advertising will reach $4.8 billion by 2013.

Currently revenue from data charges is significantly higher than that generated by mobile advertising, but the report indicates that this trend will diminish over the next 5 years. It also predicts that 40% of mobile search advertising will be caused by local search advertising.

The report states that the following factors will lead to the adoptions of mobile search advertising:

• Enhancements to the user interface resulting in an improved user experience while searching
• The gradual decline of the operator “walled garden” approach
• Reduction in data costs and increasing availability of flat rate data tariffs
• The impetus provided by major search brands such as Google and Yahoo!

Google CEO Eric Schmidt has repeatedly spoken about their plans to expand the AdWords mobile advertising programme. Google has already forged partnerships with leading manufacturers like Nokia and BlackBerry as well as the world’s biggest operators such as China Mobile and Vodafone. Yahoo! has similar links with T-Mobile and Hutchison’s 3.

The report also predicts that China and the far East regions will generate the most mobile ad spend followed by Western Europe and North America.
