App Indexing on the Google SERPs
Google is indexing more content from within mobile applications, extending the program it released back in Dec. 2013 that enables users to see results from the apps they have installed, and enabling them to go directly to the content within those apps.
Google added more apps with the indexing capability in April and May of 2014 and just recently (late last week) announced that apps like ABC News, Airbnb, AutoTrader, BuzzFeed and many, many others are joining in.
Google also announced that any Android developer can now participate in app indexing, so expect to see even more of your favorite apps appearing organically in the search results (just like websites).
End-users will also notice that apps now appear differently in the search results, title links for apps take users directly to the content inside the app. Users can tell if a result will take them to an app by looking at the green text just below the listing title.
"If the green text is the name of an app you've installed and has an app icon next to it," according to Google, "then you’ll know the result will link to an app. If the green text is a website URL, then you know the result will link to a webpage.
