Marking the first time that members will see ads not triggered by their actions, Facebook has introduced a new non-social ad unit for mobile developers.

Recently there has been a lot of debate surrounding the effectiveness of Facebook’s mobile ads. Now the social network is testing a new unit, called “mobile ads for apps,” which allow you to buy exposure for your app in the mobile News Feed.

Mobile ads for apps will appear alongside organically surfaced app recommendations in a suggested applications box. If an individual, who doesn’t already have the app, clicks on an ad, he or she will be directed to the App Store or Google Play to download it.

The new unit runs on a cost-per-click model, meaning that you can set a daily budget and bid for clickthroughs. You can also customize your target audience, adding specific preferences for region, gender, and age.

According to Facebook, in the past 30 days it has sent people to the App Store and Google Play 146 million times through clicks from News Feeds, Timeline, bookmarks, and App Center.

This opens up an entirely new advertising opportunity, allowing you to target anyone — regardless of whether you have a relationship with a specific group. Facebook is currently testing mobile ads for apps with a small group of beta partners. You can sign up if you’re interested in participating.
