The plugin very useful for companies (such as Alfa Romeo, Bosch, Biir, Siemens) and blogs who have different web-sites for not logged in visitors from different countries. 
It creates Settings page named Country Redirect in the WordPress’s admin section where it is possible to point redirect for any country in the world. And when unauthorized visitor visits the frontend site, this visit will be redirected to URL matched the country he visits from with the WordPress default <code>302</code> status.
