App monetisation exchange inneractive has released the latest stats from its data analytics labs, which show a direct correlation between mobile advertising clickthrough rates (CTR) and device screen size. The analysis of millions of mobile ads over several months showed that the larger the device screen, the higher the chance of the user clicking on the ad.

Indeed, if an ad is accessible via a tablet device, it increases the chance of a clickthrough by up to three times, compared to a similar ad on a standard mobile device screen. The stats also reveal that the iPad is the most prolific mobile tablet device for increased CTR, followed by the Blackberry Playbook.

“Developers are facing many challenges when it comes to the monetisation of mobile apps, as the pay-per-download model is only really financially viable for major publishing houses,” notes inneractive president and co-founder. “We noticed a very interesting correlation between screen size and CTR, which shows the importance of supporting tablet devices that have larger screens, such as the iPad, Blackberry Playbook or Samsung Galaxy Tablet, if developers want to maximise their revenue earning opportunities.”

inneractive offers mobile developers an application monetisation exchange which enables them to maximise income by incorporating mobile ads into their apps.
