Google's new CEO, Sundar Pichai, answered questions in last nights Google's earnings report and said a tidbit that I never heard before, but I am told might not be new.
He said that "40% of searches now return app indexing results in the top five results." That is a pretty big stat and Aaron Wall also called it out on Twitter.
I did ask Google for more details, i.e. is this just 40% of specifically mobile search or all of search? He just said "search" in general and didn't mention mobile but he was reference App Indexing, which can only currently surface on mobile searches.
Here is the video at the start of where Sundar said this.
App indexing is going to be huge, I think.
