Geolocation in Wembaster tool is for a website that targets a single location. If you target multiple country, you should not set any regions.The most useful way is to focus on the country-specific pages and promote that pages to the specific country's audience
Some one told me that it too old strategy and country-specific pages are not safe it is easy to hack even we install SSL certificate also. Request you please suggest me about that query.
You can create the subfolders based on the particular countries and optimize them using the country based keywords.
depending on your cms you can target specific geos and optimize accordingly for country or language specific keywords.
