With Spotlight Search in iOS 9 it’s much easier to be redirected to apps you want to access, so why would you even need to use search engines to look for these things? That’s what Google is trying to fight against. The company’s hoping you still use its search engine to do as much you can, even in Apple’s iOS ecosystem. And so this time if you search for iOS apps or contents in these apps within Google search, you will be redirected to the downloaded app or to the App Store. Previously, you could only do this in Google Chrome browser or Google app. But now you can also do this within the mobile Safari app.
