Kenny Mathers, Director of Developer Programs and Monetisation at Nokia, introduces Nokia Ad Exchange (NAX). Kenny describes how NAX offers a really simple way for you to monetise your free apps. A single line of code adds ads from over 120 advertising networks to your app, ads that can be delivered in over 200 countries. To help you make the most of NAX, Kenny explains that it includes a powerful analytics feature. With this feature you can see how ads are being consumed and use this information to optimise you revenue. Using NAX you can also run campaigns to promote your apps and reach more users.
