look which kw are searched in the country you like to rank for .... optimise your post for that .... and then rank them .......
For popular keywords and search terms you can use Google Trends, you can sort out by country, etc.
Use social media (I also suggest creating FB group as they tend to grow much faster than pages), target countries that you want in paid advertisements.
Keep testing and experimenting - maybe your product can be popular in other continents too.
