Correction, Google shows ads based on what you search for, which locations you visit, who you communicate with, what kind of photos you take, who’s in the photos you take and so on. All the data collected by Google is intended and used to shove ads to you, since ads is the biggest money earner for Google by a huge margin. None of the Google services are provided “free” out of some benevolence.

If you’re using Android, Google has been snooping on you a lot more often than Facebook could dream of.

You know Google owns an ad network right? They show ads on lots of sites around the internet, not just on Google search results. They use data from Google Analytics to track you around the web.
