Introduction
Kakao is the dominant digital platform in South Korea, making it a key advertising channel for foreign brands. KakaoTalk, the Korean version of WhatsApp or WeChat, is the most widely used messaging app in South Korea and plays a central role in daily communication. Research from the Korea Press Foundation shows that 98.9 percent of respondents use KakaoTalk. Beyond messaging, Kakao spans e-commerce, mobility, finance, and entertainment, allowing brands to engage consumers across multiple touchpoints.
Unlike global platforms, it offers precise audience targeting and seamless integration with KakaoPay for frictionless transactions. For businesses entering Korea, working with a social media marketing agency in Korea ensures campaigns are optimized for this unique digital landscape, maximizing reach and conversions.
In our previous article, we explored Kakao Bizboard and Bizboard CPT Ads, which are highly effective for high-visibility, native placements within KakaoTalk’s chat list. These ads are ideal for brand awareness and driving large-scale traffic due to their premium positioning. However, for more diverse placements across Kakao’s ecosystem, Kakao Display Ads offer a broader reach. They allow advertisers to appear across various Kakao services, from e-commerce and mobility to entertainment platforms, making them well-suited for multi-touchpoint engagement and performance-driven campaigns.
This article will explore how foreign brands can leverage Kakao Display Ads to build a strong presence in Korea’s digital landscape.

Where Do Kakao Display Ads Appear? Placements
Kakao Display Ads provide advertisers with extensive exposure across Kakao’s ecosystem, ensuring visibility on platforms that South Korean users engage with daily. Understanding where these ads appear, how they are charged, and their cost structure is crucial for businesses looking to run effective campaigns.

Kakao Display Ads are integrated into multiple digital environments, maximizing their reach across different user interactions. These ads can appear on:
- KakaoTalk – Ads are displayed in the Friends tab, Chats tab, and Open Chat tab, reaching users as they browse through their contacts and conversations.
- Daum – Kakao’s web portal, where display ads appear within content feeds and search result pages.
- KakaoStory – A social media platform where ads are inserted between user-generated content, similar to native social media ads.
- Kakao Services – Ads can also be placed within Kakao’s other services, such as KakaoMap, KakaoPay, and KakaoShopping, reaching users during their daily digital activities.
- Partner Networks – Kakao’s advertising extends beyond its own platforms, displaying ads on third-party websites and apps within its affiliate network.
These placements ensure that advertisers can connect with users at multiple touchpoints, whether they are chatting, reading news, browsing social media, or using everyday services.
How Are Kakao Display Ads Charged? Cost Structure
Kakao Display Ads operate on different bidding and charging models, allowing advertisers to optimize their budget based on their marketing goals. The three primary charging methods include:
- Cost-Per-Click (CPC) – Advertisers are charged only when a user clicks on their ad, making this model ideal for driving traffic to a website or landing page.
- Cost-Per-Mille (CPM) – Ads are charged per 1,000 impressions, which is useful for brand awareness campaigns that prioritize visibility over direct clicks.
- Cost-Per-Action (CPA) – Ads where advertisers are charged based on specific conversion actions, such as a user making a purchase or installing an app. Only for Display conversion campaigns and Kakao channel campaigns.
The bidding strategy (manual or automatic) also affects how costs are determined. Manual bidding allows advertisers to set their own bid amounts, while automatic bidding lets Kakao’s algorithm optimize bids for the best results.
Budgeting Considerations
Advertisers can set a daily budget, ensuring they maintain control over their spending. However, it’s important to note that:
- If ad spending exceeds the daily budget, ad delivery will automatically stop.
- There may be slight overcharges if the system has already begun serving impressions or clicks before the budget cap is processed.
- Advertisers should carefully plan their bidding strategy, budget distribution, and campaign scheduling to avoid unnecessary overspending.
By understanding Kakao Display Ads’ placements, cost structures, and bidding models, businesses can make strategic decisions that maximize ad performance while controlling expenses. For foreign companies, leveraging these insights ensures that their campaigns are optimized for success in South Korea’s competitive digital market.
Benefits and difficulties of Kakao Display Ads

How to Register as a Foreign Business for Kakao Ads
Foreign businesses aiming to advertise on Kakao must follow a structured process to access Kakao Moment, the platform’s advertising management system. Since Kakao primarily caters to the Korean market, international advertisers cannot directly register a Biz Account or run ads independently. Instead, they must partner with a local entity that can create and manage the account on their behalf, including handling payments.
The process begins with creating a Kakao Account, which serves as the foundation for accessing Kakao’s business services. Once the Kakao account is approved, the business must create and upgrade a KakaoTalk Channel to a Business Channel. Official business documentation is required for verification, and in some cases, additional authentication may be necessary.
Once all steps are finalized, foreign businesses can start running display ads through their local partners, targeting South Korean consumers, and optimizing their campaigns for maximum effectiveness.
For businesses unfamiliar with Kakao’s advertising system, working with a social media marketing agency in Korea can simplify the process and ensure a smooth setup.
Conclusion
Kakao Display Ads offer a powerful way for businesses to reach South Korean consumers through highly visible, seamlessly integrated, and precisely targeted advertising. Whether the goal is to drive traffic, increase conversions, or boost brand awareness, Kakao’s extensive ecosystem provides the tools and placements necessary for success. However, foreign businesses must navigate the registration process, optimize their targeting, and adapt their campaigns to fit the preferences of Korean users.
For brands looking to expand into Korea, understanding and leveraging Kakao Display Ads is essential. With the right strategy, businesses can tap into one of the most engaged digital audiences in the country and drive meaningful results.
