17 Best Marketing & Advertising Agencies in Korea

Marketing in South Korea can be challenging for international companies who are unfamiliar with the local language and culture. Advertisers need to be aware that Korea is very invested in culture marketing. To succeed in the Korean market, brands need to thoroughly research consumer behavior, culture, and the latest marketing trends. 

Changes in Korean Consumer Behavior

Korean consumers are digital savvy, with over 85% of the population owning a smartphone. E-commerce markets are rapidly growing since more than 80% of Korean citizens are active online shoppers. 

South Korea’s digital ecosystem is unique because a large part of it is isolated. For example, the leading search engine in Korea is not Google, it’s Naver, and the leading messenger app is not WhatsApp, it’s Kakao. However, global social media platforms are dominating Korea, including YouTube, Instagram, and TikTok.

For consumer decision making, influencer testimonials are powerful tools. Korean people love brands with authenticity and trust. Therefore, brands should consider working with social media influencers to create genuine reviews.

Brand preferences in Korea are also shifting, with the younger generation more conscious about environmental issues, so they pay more attention to sustainable brands. For example, the nation’s second-hand market is becoming more popular.

There are numerous marketing companies in Korea that can help you to navigate this new market, so we have listed the 17 best marketing and advertising agencies in South Korea. These agencies are experts in many fields – influencer marketing, SEO, digital billboards, web development, and many more.
