With the same caveats as always, mobile advertising company Smaato have released numbers on their mobile advertising platform that show Symbian leading the click through rates of the leading mobile operating systems, and performing well above the average rate.

With the rates averaged out at a baseline of 100, Symbian scored 156, with only Windows Mobile (114) and ‘Feature Phones’ (123) performing above average. the iPhone hit 89, Android 58 and RIM 35.

Techcrunch reports the metrics are based on 36 ad networks and aggregated over 4 billion ad requests.

Mobile advertising will be one of the key drivers for new software and applications over the next few years, and the increase in reports and press from the Ad Networks, no matter what slice of the market they are looking at and reporting as the “leading” contender is a by-product of the rising tide. There is more awareness, there is more inventory, and it is bringing in money and impressions for everyone concerned.
