Millennial Media has released updates to its mmDev developer website. The updates help app devs to test ads on their creations and also optimise ad selection. 

The first update to mmDev is Test Device Registration. This allows developers to register up to 100 devices with the system, so that they can test how ads look when served to a variety of operating systems and devices. This feature integrates with the mmDev SDK. 

The second update is called App Store Sync. This works with iOS apps, and serves to optimise the kinds of ads that are sent to different types of apps, depending on the theme of the app – such as sport, weather, or other categories. 

The developer just has to enter the App Store URL of the app in question, and the optimiser extracts the important information from the App Store description, says Millennial. 

To go with the updates, the company has posted a blog that explains the new features and also offers best practises for app developers. You can read it here.
