Geo-Targeting in CloudFront

Hello All, I am preparing for some AWS interview questions and I want to know what do you understand by geo-targeting in CloudFront? As I know it supports the creation of customized content for the target audience as per the demand and needs of a specific geographical area but I want to know more about it. If anyone know, Please explain me.

CloudFront will detect the user’s country of origin and pass along the county code to you in the CloudFront -Viewer-Country header. You can use this information to customize your responses without having to use URLs that are specific to each country.
