Oh, How Pinteresting!
This is a great addition for Pinterest users as 75% of Pinterest's traffic is from users on mobile devices. Part of what makes the Pinterest App Pins announcement so cool is that App Pins are not ad units. More app discovery and user feature than a monetization play by Pinterest. Along with this announcement - Apple has created an "App Store Board" where they feature various apps on fashion and recipes. Pinterest currently only supports app downloads for Apple/iOS, sorry Android users....
The Largest Social Networks by Alexa Rank are:
Key Stats: 84% of its daily audience visits from a mobile device, and 69% of ad revenues coming from ads shown on mobile. Support Direct App Installs?: YES - from Ads Only
Key Stats: 80% of active users are on mobile. Support Direct App Installs?: YES - via App Cards App Cards are essentially "rich" tweets that can be posted and/or promoted - but promoting is not required. Because the lifespan of a tweet is roughly 17 minutes - finding the right mix of sponsored tweets is probably required for any significant user acquisition efforts.
Key Stats: 65% of users access via mobile device. Support Direct App Installs?: YES - via Tumblr Sponsored Apps
Key Stats: 50% of video views are from mobile devices. Support Direct App Installs?: ** Yes - with "TrueView for mobile app promotion". **
LinkedIn - not yet. Will probably add this feature when more B2B, SMB and/or Enterprise companies adopt mobile for their target market, clients, partners or employees. Of the newer social media platforms - including Instagram, Vine, and SnapChat - none currently support direct app installs and the fit/need is not clear as these platforms continue to grow and evolve.
