Google has included contextual search results (links to content from installed apps, not just web pages) for Android users since 2013. Today, iOS users will be able finally be able to do the same. Following up on its reveal during the I/O event last week, Google explained on the Inside Search blog that the company will populate search results with in-app content for both the Google App and Chrome on iOS devices starting this week. So if you tell your iPhone, like in the example below, "I need a reservation at Bombay Cricket Club" Google will return a link to the OpenTable app that takes you directly to the Bombay Cricket Club's reservation page.
This feature isn't universal just yet. Initially, Google's only returning results from a small batch of early partners including Eat24, Free Dictionary, Huffington Post, OpenTable, Pinterest, SeatGeek, Slideshare, Tapatalk, Yellow Pages, YouTube and Zillow. If you don't have any of these apps yet, don't worry. Google also announced today that it will begin popping links to apps that you haven't yet installed but probably should -- just like it already does on Android.
