A Korean landing page converts when it is rebuilt around how Koreans actually browse, pay, and consent, and it stalls when it ships as a translated copy of the English page. Three things decide the outcome: a mobile-first layout, a form and checkout flow that matches Korean habits and Korean law, and the disclosures Korean buyers expect to find before they trust an unfamiliar foreign brand.
This is the page-level layer of a Korean program. The channel map above it, covering where Korean traffic comes from in the first place, is set out in the guide to digital marketing in Korea. The decision this article covers is narrower and comes later: once you are paying to send Korean traffic somewhere, what does that destination have to be.
The executive framing matters here because landing page work gets delegated early and reviewed late. A director approves a Korea campaign, the media plan gets built, and the destination page is treated as a translation ticket. By the time anyone reads the conversion data, the spend is committed and the page has been failing quietly for a quarter.
Why does a translated landing page underperform in Korea?
Translation moves words. Conversion depends on layout, proof, payment, and legal disclosure, and all four differ in Korea.
Start with the screen. Korean commerce is overwhelmingly mobile: in July 2026, mobile accounted for 78.0 percent of Korea’s online shopping transaction value, 19.5716 trillion won out of 25.0954 trillion won, according to the Ministry of Data and Statistics release published on 1 September 2026. That figure appears in the release’s narrative summary, and the two transaction values it cites divide out to 78.0 percent, so the stated share and the underlying numbers agree.
A page designed desktop-first and then made responsive reads as an afterthought on the device most Korean buyers use. The practical failures are consistent: hero images with text baked in at desktop proportions, forms that require pinch-zoom, comparison tables that scroll horizontally, and calls to action that land below three screens of narrative copy.
The second difference is proof. Korean buyers verify unfamiliar brands before converting, and they verify outside your page. A landing page that carries no Korean-language corroboration and no evidence the company exists in Korea asks for a decision the visitor is not ready to make. The behavioral pattern underneath this, and the assumptions foreign teams get wrong about it, are set out in the guide to Korean consumer behavior.
What does Korean law require on a commercial page?
If the page sells or takes orders, Korean law puts specific identifying information on the site itself, and the requirement sits at the level of the page rather than a buried terms document.
Article 10(1) of the Act on Consumer Protection in Electronic Commerce (consolidation in force 21 July 2026) requires the operator of a cyber mall to display the company name and representative’s name, the business address including where consumer complaints are handled, the telephone number and email address, the business registration number, and the terms of use. Article 7(1) of the Enforcement Rule (in force 21 July 2026) sets where: those items go on the initial screen of the cyber mall, in a form consumers can easily read, with the terms of use permitted to sit behind a link.
This is why Korean commercial sites carry that dense block of company identifiers near the footer. Foreign teams routinely strip it during design review because it looks like clutter. It is a statutory display requirement, and its absence is one of the first things a cautious Korean buyer notices.
Article 13(1) adds, for advertising aimed at soliciting orders, the trade name and representative’s name, the address, telephone number and email address, and the mail-order business filing number together with the authority that received the filing. Companies whose principal office is outside Korea file with the Korea Fair Trade Commission rather than a local district office, under Article 13(1) of the Enforcement Decree (in force 21 July 2026). Article 12(1) exempts filings below a threshold the KFTC sets by notice, and that notice, KFTC Notice 2022-4, exempts a seller with fewer than 50 transactions in the preceding year or one registered as a simplified taxpayer under the Value-Added Tax Act.
One more provision shapes page copy directly. Article 17(1)(1) gives the consumer seven days from receiving the written contract terms to withdraw an order, running instead from delivery where the goods arrive later. A Korean page that presents a stricter returns policy than the statute contradicts a right the buyer already has.
How should the form and consent flow work?
Korean consent law is granular, and it changes form design rather than just the privacy policy.
Article 22(1) of the Personal Information Protection Act (consolidation in force 11 September 2026) requires the controller to separate each consent item and make each one clearly recognizable. Subparagraph 7 of that paragraph singles out consent obtained for the purpose of promoting or soliciting the purchase of goods or services, which must be taken separately from the consent that covers the transaction itself. Article 22(5) then prohibits refusing the service because the person declined an optional consent. A single bundled “I agree to the terms and to receive marketing” checkbox, standard on many English pages, fails both provisions.
The presentation of those items is also prescribed. Article 4 of the Personal Information Processing Methods Notice (PIPC Notice 2026-10, issued 20 August 2026) requires the important content to be marked so the person can easily recognize it, through font size, color, weight or underlining, and to be set apart from surrounding text where the volume of consent items would otherwise obscure it.
A Korean team often reaches an existing component here before designing its own screen. Kakao Sync extends Kakao Login with a 간편가입 consent screen, and Kakao’s developer documentation, retrieved 15 September 2026, describes that screen as presenting three separate groups: consent to Kakao providing user information such as name, email, phone number, age range and birthday, consent to the service’s own terms, which the documentation lists as covering items like the terms of use, the privacy policy and marketing use consent, and consent to adding the service’s KakaoTalk channel. The same documentation describes checking which terms a user has already agreed to, asking only for outstanding required terms, and requesting withdrawal of a particular consent item. That is the item-level granularity Article 22 expects, presented in a screen Korean users have seen before.
Two more constraints catch foreign teams. Article 22-2(1) of PIPA requires the legal representative’s consent before processing the personal data of children under 14, and requires the controller to verify that the representative actually consented. And Article 23-2(1) of the Network Act (consolidation in force 11 September 2026) bars information and communications service providers from collecting resident registration numbers except in narrow listed cases. Form designs ported from markets where a national ID field is routine run straight into that prohibition.
The lawful route sits in the same act. Article 23-2(2) defines an alternative means, 대체수단, as a method of confirming a person’s identity without using the resident registration number, and Article 23-3(1) empowers the Korea Media and Communications Commission (방송미디어통신위원회) to designate as an identity verification agency, 본인확인기관, a body it judges capable of safely developing, providing and managing that alternative means. So the advertiser calls a designated agency’s verification service and receives a confirmed identity, keeping the number out of its own form and its own database. The Korea Internet and Security Agency’s identity verification portal lists the designated agencies by method (본인확인기관 현황, retrieved 15 September 2026): i-PIN, mobile phone, credit card and certificate, with mobile phone verification provided by SK Telecom, KT and LG Uplus. A Korean page that needs a verified identity calls one of those services.
What you send afterward is regulated separately. Article 50(1) of the Network Act requires explicit prior consent before transmitting advertising for profit through an electronic medium, and Article 50(3) requires a second, separate consent for sending between 9pm and 8am through any medium except email. Article 50(4), through Article 61(3) of the Enforcement Decree and Annex 6 (as amended 5 January 2021), sets the format: for email, “(광고)” at the start of the subject line, the sender’s name, email address, telephone number and address in the body, and an opt-out notice with a working technical mechanism, stated in both Korean and English. Article 62-3(1) of the same Decree requires confirming every two years that the recipient still consents.
What does a Korean landing page need at checkout?
Korean buyers have moved decisively to simple payment services, and a checkout offering only international card entry misses the dominant habit.
The Bank of Korea’s release on electronic payment service usage during 2025, published 20 March 2026, reports simple payment services averaging 35.57 million transactions and 1.1053 trillion won per day, up 14.9 percent and 14.6 percent respectively on the previous year. I verified these against the release’s own table, which gives 3,557.3 (ten thousand transactions) and 11,052.5 (hundred million won) per day, matching the narrative figures. The same release records electronic finance businesses, the registered non-bank payment operators such as Naver Pay and Kakao Pay that the Bank of Korea counts separately from phone manufacturers and financial companies, holding 54.9 percent of simple payment value in 2025, up from 50.5 percent in 2024.
For a landing page, the consequence is structural. If the conversion event is a purchase, the payment step has to be built against a Korean payment gateway that carries those services. Toss Payments’ developer documentation on institution codes, retrieved 15 September 2026, lists the simple payment providers it supports as Toss Pay, Naver Pay, Samsung Pay, Apple Pay, L.Pay, Kakao Pay, Pin Pay, Payco and SSG Pay. A checkout built only around international card entry offers a Korean buyer none of them.
If the conversion event is a form fill, the equivalent work happens at identity and consent. The page hands verification to a designated agency’s alternative means described above, and the consent block either reproduces the separated items Article 22 requires or adopts a component such as Kakao Sync that already presents them.
What copy and claims actually convert?
Claims that pass legal review in the United States can breach Korean advertising law, and the exposure sits with the advertiser.
Article 3(1) of the Act on Fair Labeling and Advertising (in force 21 January 2025) prohibits false or exaggerated labeling and advertising, deceptive labeling and advertising, unfair comparative advertising, and defamatory advertising, where the conduct is likely to deceive or mislead consumers and undermine fair trading order. Under Article 7(1), the Korea Fair Trade Commission can order the conduct stopped, order publication of the fact that a corrective order was issued, and order corrective advertising. Superlatives, unqualified performance claims, and competitor comparisons transplanted from an English page are the usual triggers.
Price presentation has its own rules. The Consumer Protection Guidelines for Electronic Commerce (KFTC Notice 2025-8, issued 24 October 2025) address the screen where a consumer first encounters a product and its price, and treat the total amount a consumer must unavoidably pay as including mandatory service charges, taxes and fees, and shipping and installation costs where these are not genuinely optional. A page that advertises a headline figure and reveals mandatory additions later is the pattern those guidelines exist to stop.
Then there is the language itself. Korean search and Korean buyers use terms that are frequently not the dictionary translation of your English keyword, which changes headline copy as much as it changes metadata. That problem, and the method for solving it, are covered in the guide to Korean keyword research and why direct translation fails.
What does Korean accessibility law require of a commercial website?
Web accessibility in Korea rests on anti-discrimination law rather than on a voluntary standard.
Article 21(1) of the Act on the Prohibition of Discrimination Against Persons with Disabilities (in force 11 November 2025) requires the actors it covers to provide means, including text, so that disabled people can access and use the electronic information they produce and distribute. Article 14(2)(1) of the Enforcement Decree (in force 22 January 2026) specifies what that means for the web: a website whose accessibility is assured so anyone can use the service regardless of physical or technical circumstances. Article 14(1) assigns the staged scope of covered actors to Annex 3, which phases coverage in by actor type: public institutions from 11 April 2009, and legal persons under Article 3(8) of the Act that no other annex covers from 11 April 2013.
The technical standard is the Korean Web Content Accessibility Guidelines 2.2, national standard KS X OT0003, revised 28 December 2022. The National Information Society Agency’s release on that revision describes it as adding nine inspection items to the existing 24, for 33 in total, and cites Article 21 of the anti-discrimination act and its Enforcement Decree Article 14 as the legal basis. Building to that standard from the start costs little; retrofitting a finished page costs considerably more.
What should you fix first?
Sequence the work by what blocks conversion soonest.
The disclosures come first, because they are binary and cheap. Company identifiers on the initial screen, an accurate returns statement, and a correctly separated consent flow either exist or they do not.
Layout comes second. Rebuild the page for a phone, with the primary action reachable without scrolling through translated narrative copy.
Payment or form flow comes third, and this is the expensive one, because a Korean payment gateway is an integration rather than a design change. Scope it before the campaign launches instead of discovering it during it.
Proof comes last in build order and first in conversion impact. A Korean phone number, a Korean address, Korean-language corroboration, and evidence of local presence do more for an unfamiliar brand than another round of copy revision.
Common failure patterns
Treating the page as a translation deliverable. The words are the smallest part of the work.
Keeping the English form fields. Name order, address format, phone format and consent structure all differ, and a national ID field is prohibited outright for most collectors.
Bundling consents to raise opt-in rates. This breaches Article 22(1) of PIPA and voids the marketing permission you thought you gained.
Stripping the company identifier block in design review. It is a display requirement under the Electronic Commerce Act, and Korean buyers read it as a trust signal.
Launching paid traffic before the destination is finished. Korea is an expensive place to learn that a page does not convert.
Frequently Asked Questions
Do I need a Korean entity before running a Korean landing page?
Not necessarily for a page that only collects inquiries. The obligations described here attach mainly to selling and order-taking. Where a company does file as a mail-order business, Article 13(1) of the Enforcement Decree routes filings from companies whose principal office is abroad to the Korea Fair Trade Commission. Decide whether the page sells or only generates inquiries before designing it.
Is machine translation ever acceptable for a Korean landing page?
Not for anything a buyer reads before converting. Korean readers identify machine-translated marketing copy immediately, and on a page asking for payment or personal data that recognition reads as a reason to leave. Machine translation is workable as an internal drafting aid, with Korean-native writing and review producing everything that ships to the visitor.
How many consent checkboxes does a Korean form actually need?
Enough to separate each purpose. Article 22(1) of PIPA requires consent items to be distinguished and individually recognizable, and subparagraph 7 requires promotional and sales-solicitation consent to be taken separately. Article 22(5) prohibits refusing service because someone declined an optional item, so optional consents must be genuinely optional in the form logic.
Does a Korean landing page need to be on a .kr domain?
No statutory requirement forces it. The practical considerations are trust signals and hosting performance for Korean visitors, which a subdirectory on the main domain can also address while keeping accumulated authority in one place. Decide this alongside the wider Korean site structure rather than page by page.
Where to Take This Next
Landing page localization sits at the boundary between strategy and build. The decisions above are the ones a director owns: whether the page sells or generates inquiries, what the conversion event is, and what the page has to carry legally before traffic reaches it. The execution beneath them, including the build itself, is delivery work. Inquivix sets out that layer in the Web and Creative Solutions section of its Korea digital marketing services, covering website localization, UX adjustments and landing page optimization for the Korean market.
Inquivix is a Korea-based agency handling Korea market entry and digital growth for international brands, including Korean site and landing page localization, Naver and Kakao channels, and paid media across Korean platforms. If your Korean traffic is arriving at a page that was translated instead of localized, that is the fixable part.
