  • Websites and apps that you’ve visited that belong to businesses that advertise with Google
  • Your activity on another device
  • Your previous interactions with Google’s ads or advertising services
  • Your Google Account activity and information

You can control how Google personalises Google ads, or turn off personalisation of Google ads, at Ads Settings
