AI SEO in South Korea: how to get recommended by ChatGPT and Google AI search

By Rahil Jain, founder of Chalk LabsUpdated How we research

The short answer

To be recommended by ChatGPT and Google AI search in South Korea, publish native Korean pages with price, scope and proof, and let OAI-SearchBot and Googlebot read them. Plan for two engines, because Naver leads on mobile while Google leads across all devices. Keep business facts identical on your site, Naver and KakaoTalk, and follow the Personal Information Protection Act on every form.

  • Naver took 59.56% of Korean mobile search referrals in September 2026, ahead of Google at 35.77%, but Google led all devices at 47.97%.
  • Microsoft puts Korean generative AI use at 40.6% of people aged 15 to 64 in June 2026, up 3.5 points in one quarter.
  • KakaoTalk had 49.1 million monthly users, so customers expect to message you there.
  • Naver surfaces blogs, Cafe communities and Knowledge iN answers, so your brand may be judged by content you do not own.
  • Chalk Labs has no published Korean client result. Its only regional proof is Meru Trophy in Bengaluru, India.

How do people in South Korea search and use AI?

They use two engines, and the split depends on the device. In September 2026 Naver held 59.56% of Korean mobile search referrals and Google held 35.77% 1. Across all devices Google led at 47.97% and Naver followed at 43.06% 2. These shares count visits from a search engine, not searches typed, and they exclude AI assistants.

AI use is among the highest in the world. Microsoft's AI Economy Institute reports that 40.6% of South Koreans aged 15 to 64 used a generative AI product in June 2026, up from 37.1% in March, the largest absolute rise that quarter at 3.5 points 3. The world figure was 18.8% 3. The measure counts any generative AI product, not ChatGPT alone.

Connectivity is near universal. DataReportal counted 50.6 million internet users in October 2025, which is 97.9% of the population 4.

Microsoft estimates that 40.6% of South Koreans aged 15 to 64 used a generative AI product in June 2026, more than double the 18.8% world figure and a 3.5 point rise in one quarter 3. It counts any generative AI product, not ChatGPT alone.

Build local prompts for South Korea

Pick a business type and a place. Copy the prompts, then ask them in the AI assistants your buyers use and see who gets named.

Your 5 prompts

  • Gangnam dental clinic 추천
  • Gangnam dental clinic 가격
  • Gangnam dental clinic 후기
  • dental clinic Gangnam 비교
  • Gangnam 근처 dental clinic

These patterns are modelled, not observed. 추천 means recommend, 가격 means price, 후기 means reviews, 비교 means compare and 근처 means near. Replace the English type with its Korean term before you test, keep each page in one language, and drop place and type pairs that do not occur in real life.

Why do you need a plan for both Naver and Google?

Because each engine decides differently, and your buyers use both. A phone user may start on Naver, while a desktop researcher may start on Google. Ignoring either leaves a large share of discovery to competitors.

The table compares what each engine mostly draws on, based on the sources we opened. It is a working map to test, not a ranking formula.

What is KakaoTalk's role in finding a business?

KakaoTalk is where customers message you, not the page an AI cites. DataReportal reports 49.1 million KakaoTalk monthly users, which is 95.1% of the population 4. YouTube's ad reach was 42.9 million, which is 83.1% of the population 4. Those are estimates, not exact active users.

We did not test whether AI assistants read KakaoTalk content, so we make no claim about it. Put your prices, hours and policies on a public page you control. A customer who asks on KakaoTalk how much a service costs should find the same range on your site.

How should you write Korean pages for AI search?

Write them in natural Korean, with the answer in the first two sentences. Google's AI Overviews list Korea as a location and Korean as a supported language 6. The help page says only 'Korea' without naming the country, so test your own results before you rely on it. Google also says fully translated pages are not duplicates, and that language versions should link to each other with reciprocal hreflang tags using the ko code 7.

Modelled Korean query patterns help you choose headings. We have not observed these, so test them in your own search tools.

What do PIPA and the marketing rules mean for your site?

The Personal Information Protection Act (PIPA) is enforced by the Personal Information Protection Commission. Controllers generally need explicit consent before collecting or using personal information, with separate consent for each processing activity and data type 8. A PIPA amendment passed in March 2026, with most provisions effective 11 September 2026, raises the maximum administrative penalty from 3% to 10% of total revenue in specific cases, such as repeated willful violations or breaches affecting 10 million or more people 8. Cross-border transfers generally need consent, with listed exceptions 8.

Advertising messages by electronic media need the explicit consent of the person under the Network Act. Senders must identify themselves and give opt-out instructions, and may not auto-generate contact details or hide their identity 9.

The sources we read do not say how PIPA reaches a foreign firm without a Korean presence, and they do not cover advertising claim rules 8. Ask a Korean lawyer. This page is not legal advice.

How does South Korea differ from the global playbook?

The global playbook assumes Google. In South Korea you also need a Naver plan, a Korean-language site and a presence where Korean customers talk. AI adoption is also well ahead of the world average, so the shortlist your buyer sees may already be an AI summary.

The technical basics stay the same, but you have more doors to open. Allow both Googlebot and OAI-SearchBot 10, and register the site with Naver as well. Google adds no extra requirements beyond being indexed and snippet-eligible 11. The robots.txt guide has the steps.

For another market with a strong local search player, compare the Japan page. For a market where Vietnamese-language search and Zalo matter, see the Vietnam page.

What has Chalk Labs actually done in South Korea?

Nothing we have published. Chalk Labs has no Korean client case or result, and this page does not imply one. Our only published regional result is Meru Trophy, a trophy shop in Bengaluru, India, which reached 27,300 Google clicks and 2.3 million impressions in 16 months 12.

That result came from Google, not Naver, and from a different language. What transfers is the method: query research, answer pages, technical readiness and measurement. We do not guarantee rankings or citations.

Where should you start this month?

Split the work in two, then measure each engine on its own.

  • Week 1: confirm robots.txt allows OAI-SearchBot and Googlebot, and read Naver's webmaster guidance.
  • Week 2: align your business name, address, phone and KakaoTalk contact across your site, Google Business Profile and Naver.
  • Week 3: publish a pricing page, a service scope page, a comparison page, a location page and one case summary in native Korean.
  • Week 4: run ten shortlist prompts in Korean on ChatGPT and Google, test the same phrases on Naver, note the date and brands named, and repeat monthly.

Rules and platforms that shape results

Rules to know

  • Personal Information Protection Act (PIPA). Enforced by the Personal Information Protection Commission. Explicit, separate consents; cross-border transfer generally needs consent; a March 2026 amendment raises the maximum penalty to 10% of revenue in specific cases.8
  • Network Act rules on electronic advertising. Advertising by electronic media needs the person's explicit consent, a clear sender identity and opt-out instructions, with no auto-generated contact lists.9

Platforms that matter here

  • Naver Search, blogs, Cafe, Knowledge iN and shopping
  • Google Search and Google Maps
  • KakaoTalk for customer messages
  • YouTube for discovery and reviews
  • ChatGPT search (reads sites through OAI-SearchBot)
  • Google AI Overviews and AI Mode
  • Naver Smart Store for sellers

What works in South Korea

  • Run two tracks: a Google and AI track for your own site, and a Naver track for the Korean community content that surfaces there.
  • Write each key page in native Korean with the answer in the first two sentences, and have a native editor review it.
  • Publish prices in won with inclusions, and a fair comparison table.
  • Invite honest customer posts on Naver and YouTube, and never post fake reviews.
  • Keep the name, address, phone and KakaoTalk contact identical across your site, Google and Naver.
  • Add a ko hreflang pair if you also serve overseas buyers in English.

Mistakes to avoid

  • Building only for Google and ignoring Naver's 59.56% mobile share.
  • Machine-translating English pages into Korean without a native review.
  • Assuming KakaoTalk chats are visible to AI assistants, which we did not test.
  • Sending marketing messages without explicit consent.
  • Buying fake reviews, which damage trust and may break platform rules.

Frequently asked questions

Is Naver or Google more important for a Korean business?

Both. Naver leads mobile at 59.56%, while Google leads across all devices at 47.97% 12. Pick the engine by where your buyers start, and track each separately.

Do I need Korean pages to be recommended by ChatGPT in Korea?

For domestic buyers, yes. Google's AI Overviews support Korean 6, and an assistant matches the language of the question. Add English pages as a separate version for overseas buyers, linked with hreflang 7.

How common is AI use in South Korea?

Microsoft estimates 40.6% of people aged 15 to 64 used a generative AI product in June 2026, against 18.8% worldwide 3. It is a broad measure of any such product, so it does not show how many people ask AI to find local businesses.

What privacy law applies to my Korean website?

PIPA applies to personal information you collect and generally needs explicit, separate consent 8. Electronic advertising also needs explicit consent under the Network Act 9. Ask a Korean lawyer how both apply to you.

Does Chalk Labs work with Korean businesses?

We have no published Korean client result. Our regional proof is Meru Trophy, a trophy shop in Bengaluru, India, with 27,300 Google clicks in 16 months 12. We do not guarantee rankings or AI citations.
