Safari includes cross-site tracking prevention, which will reduce sites like Amazon or Google from using your browsing history to suggest products in advertisements (which can be a good thing depending on your point of view). Additionally, Safari can integrate with third-party content blockers from the App Store to further reduce the advertisements you see while surfing the web.
