Nokia launched its Nokia Ad Exchange and Premium Developer Program, to coincide with the official unveiling of Microsoft's Windows Phone 8 platform.

The Nokia Ad Exchange enables developers to use in-app advertising to monetise their apps for free, and the company has partnered with mobile advertising company Inneractive to provide developers with access to 120 ad networks around the world via a single SDK.

Developers can make sure the ads that appear are relevant to their particular app, with a range of formats, including banners, full-screen, text and local ads.

It also provides analytics – such as impressions, click-through rates and total spend – via the campaign management dashboard.

A campaign management tool allow developers to use their ad revenue to fund their own advertising campaigns is also in the pipeline.

The Exchange is also open to Series 40 and Symbian developers, as well as those working with non-Nokia platforms such as Android, iOS and BlackBerry.

The Premium Developer Programme is aimed at helping Windows Phone developers improve their apps with a range of tools and services.

For a US$99 annual subscription, developers have membership to Microsoft’s Windows Phone Dev Center through which they can submit apps, and two Nokia tech support tickets for reporting issues or asking question.

Other benefits include one million API calls per calendar month for the Buddy cloud back-end, and a licence for the Telerik RadControls UI tools, which can be used to shorten time-to-market.
