First of all, you can choose the geography to which you would like your website displayed via the Google Search Console, so no biggie.
You would need to turn your visitors into leads, which would help in improving your status among your geographies.
When promoting your website to a certain crowd, you should use tools such as Google Trends or Ubersuggest with these certain geographies, as well as doing your keyword research based on these regions to appear mostly there.
Would your whole traffic come from these regions? Not necessarily, but you can also block certain geographies from entering your website (georestriction), which would help you in receiving the traffic you actually want.
Generally speaking, these basics are good to follow.
