Facebook updated its tools to enable developers to specifically target Amazon-branded mobile devices and to improve the use of video ads.

App advertisers can now target their Amazon Appstore titles towards Fire owners, much like they can with the iPhone 6 or Samsung Galaxy S5.

In order to advertise Appstore releases on Facebook for Fire tablet users, advertisers need to configure their Amazon Appstore URL in their apps on Facebook, create an ad and select the platform.

Another new tool enables advertisers to buy mobile app ads that are highly predictable in terms of reach and frequency over the course of a campaign.

An example of how this would work is that advertisers can set their campaign to reach five million people with a frequency limit of three impressions per person for a week.

Reach and frequency is optimised for unique reach, according to Facebook, meaning it is most effective for brand awareness campaigns, such as an app launch or update.

Updates to video functionality have also been made to enable video mobile app ads to play automatically in the Facebook News Feed. The auto-play function should increase the chance of them being viewed by users.

Advertisers can now also purchase mobile app ads with video creative through the Power Editor advertising tool.
