Punch Digital Marketing

While most people outside of Korea use Google, you need Naver SEO to reach Korean consumers to sell your products or services. Naver is Korea’s #1 search engine. Only two other countries that use search engines other than Google, those countries are China and Russia. Therefore if your primary target is Koreans, then Naver is vital for the growth of your business. We are talking about Naver ads, marketing campaigns, and SEO. Naver is very tricky as it differs from Google or Yahoo. Naver is more of a community platform than a search engine. They promote blogs from their platform (Naver blog) than other global sites. This is why it is better to have a Naver blog than a blog site of your own to get a high ranking on Naver.
