The geo block service allows you to block visitors from your website based on their geolocation. This is done by redirecting them away to a URL of your choice.
You can consult a step by step guide with screenshots on how to set it up here: http://help.geotargetly.com/en/articles/2147736-quick-start-guide
You can block visitors by their country, state/region, city, latitude-longitude-radius zone and IP address.
Blocking can be applied throughout your website, a particular sub directory of your website or an individual page.
IMPORTANT: Geo blocking is not 100% accurate. It is possible to get past geo blocking by using a VPN to visit your website from an alternate location. It is also possible to get past geo blocking by disabling JavaScript in the browser.
