Keyword ranking problem plz help

My website is a Korean website. I created a backlink with a Korean keyword, but why are the rankings of other countries high and the rankings of Korea low?

Maybe it is because most of the people in Korea use Naver.
Naver acts as a community platform, it distinctly divides websites and blogs, it doesn't support link tags, the keyword advertising section takes most of the 1st-page area, and so on.
Thus SEO in Naver is difficult.
