Google’s biggest search signal now is aggregate behavioral data reported from Chrome. That pervasive behavioral surveillance is the main reason Apple has never allowed a native Chrome app on iOS.

It’s also why it is so hard to compete with Google. You guys are talking about techniques for analyzing the corpus of the search index. Google does that and has a direct view into how millions of people interact with it.

Yes indeed, they have an impossibly deep moat and deeper pockets. I'm certainly not trying to compete with them with my little side project, it's just for fun!

The Chrome iOS app still knows every url visited, duration, scroll depth, etc.
