In How Google is Taking Search Outside the Box Steven Levy comments on this year’s I/O event. He does a nice job of explaining deep linking / app indexing, and the much mentioned Google Now on Tap in the context of Google’s mobile and search challenges.

Google now says that it has expanded its app indexing program to Apple’s iOS platform. “App indexing” is the practice of Hoovering up the data that lives inside apps, the first step to making that information available by Google searching — it’s analogous to crawling the web. Google has been doing this since 2013 for Android apps, essentially creating an index that lives on a simulation of a giant Android phone. And I do mean giant: there are 50 billion deep links indexed so far. (Deep links are those which take you directly to relevant information inside an app, as opposed to leading you to the front door.)

I found the 50 billion indexed deep links surprising, especially since they are almost all from Android apps, and from only a little more than half of the developers asked to participate. There is a decent developer value proposition, but it will be interesting to see what Apple decides to do to keep control of its ecosystem. And then there are Facebook, Twitter, and others. Google would most likely be the biggest beneficiary of a deep linking standard if there ever is one. Read more
