If you simply want to read a foreign-language website in Korean, tools such as Chrome’s built-in page translation, Google Translate, and Papago can help you understand the content right away. However, if you plan to publish and continually maintain a Korean version of your own website, replacing text in one language with text in another is not enough.

Are the headings and buttons natural in Korean? Are product names and action terms consistent from page to page? Is the text a readable length on screen? Translation quality for a public website must account for the entire user experience.

Drawing on real examples in which native speakers reviewed Korean drafts produced with AI translation, this article explains how to create natural, consistent Korean content. It also shows how to incorporate review findings into prompts, glossaries, and style guides so they can improve future translations.

Translating a website into Korean: reading vs. publishing

Use browser translation or a translation tool to read a foreign-language website in Korean

If your goal is to read a foreign-language website on the spot, a browser or online translation tool is a convenient option. Common methods include:

• Chrome’s built-in page translation: Translates the page you are viewing without requiring you to copy the URL or switch to another tool
• Google Translate: Opens a translated page from its URL in browsers other than Chrome and lets you switch between the source and translated text
• Papago: A translation service from NAVER that is widely used in Korea; its translation technology is also used in the NAVER app and Whale browser

These tools are useful when you want to quickly read and understand a website. However, if you need to edit translations in detail, keep terminology consistent across the site, or publish and maintain Korean-language pages, you will need a system for managing translations as well as human review.

Publishing a Korean-language website requires localization as well as translation

When publishing a Korean version of your website, the scope of translation extends beyond body copy to headings, navigation, buttons, input forms, error messages, page titles, and meta descriptions.

You must also consider whether the language sounds natural in Korean, suits the business context, fits the available screen space, and reflects the terms people use when searching. Adjusting content not only for the language but also for the usage environment, culture, and user experience is known as localization.

Four lessons from native-speaker review of Korean web and UI translations

During an internal review at Yaraku, Inc., we used AI to create an initial Korean translation of website copy and then asked native Korean speakers to review it. Although the meaning was understandable, the review identified several expressions that needed adjustment for publication. Based on actual revisions and the supplemental rules added after the review, here are four reusable criteria for making translation decisions.

1. Consider writing common romanized words in Hangul

When Korean text contains too many common English words or romanized terms, multiple writing systems compete on the same screen, making the content harder to read and the spelling less consistent. Using the established Hangul form for common words can improve consistency and readability across the text.

However, this does not mean mechanically converting every abbreviation or brand name into Hangul. In our review, the abbreviation “IR,” which is common in Korean business contexts, remained in its original form in phrases such as “IR부” and “IR 자료.” Consider Hangul for common words, but give priority to glossary rules for widely used abbreviations, brand names, and similar terms.

2. Consider formal Korean terms instead of using loanwords by default

In business and UI terminology, an English-derived expression may be understandable, yet an established native Korean or Sino-Korean term can sound more natural and give the content a more polished, professional tone. Our native review included the following revision:

Before: 바이링구얼 사용자 (“bilingual user”)

After: 이중 언어 사용자 (“user of two languages”)

Although “바이링구얼” is understandable, “이중 언어” sounds more natural in formal explanatory copy. The goal is not to avoid every loanword, but to confirm whether a term is established in Korean and whether it suits the tone of the content in which it appears.

3. Choose wording that sounds natural as web copy, not merely correct grammar

A sentence can be grammatically correct yet sound too stiff as a heading or description, or evoke the wrong context. Our review therefore included changes based not only on dictionary meaning but also on how natural the wording felt as web copy.

Revision 1: 단순하게 → 간단하게

Both can mean “simply” or “easily,” but “간단하게” sounds more natural in copy that communicates ease of use. For short taglines, review the on-screen concision as well, including whether punctuation is needed.

Revision 2: 확인·검토 공정 → 확인·검토 과정

Because “공정” is more likely to evoke a manufacturing process, “과정” sounds more natural when referring to a confirmation or review workflow.

Revision 3: 더 생산적이고 더 안심하고 → 더 생산적으로, 더 안심하고

Aligning the adjective and adverb forms improves the sentence’s parallel structure and readability. It is important to review not only the correctness of individual words but also the forms and rhythm of the sentence as a whole.

4. Translate “click” according to context instead of always using “누르다”

In an actual app UI review, the Korean translation of “Click a translation to show additional information.” was changed from “번역을 클릭하면” (“when you click a translation”) to “번역을 선택하면” (“when you select a translation”). By contrast, a link in an email uses “링크를 클릭하세요” (“click the link”), while the Enter key uses “Enter 키를 누르세요” (“press the Enter key”).

Even operations similar to “click” or “press” require different wording depending on whether the target is a selectable item, a link, or a physical key, as well as the context in which the action occurs. Choose the translation after checking the UI element and usage context, not only the source word.

Incorporate review findings into prompts and glossaries

When you use an AI translation engine to create an initial draft, include criteria like those identified in our review in the prompt. For example, you can add the following four instructions to a Korean translation prompt:

• Write common romanized words in Hangul
• Prefer established Korean terms for UI and business terminology
• Keep terminology and style consistent across the website
• Translate “click” as “누르다” or “클릭” according to context

If the instructions become too long, important conditions can get buried. Start by expressing only recurring decisions in short, clear rules. A prompt alone, however, cannot always select the right translation. In practice, it is easier to manage fixed forms in a glossary and context-dependent decision criteria in a style guide.

What to manage in a glossary

• Product names, feature names, and plan names
• User permissions and role names
• Recurring UI terms used in buttons and menus
• Brand names and proper nouns that must remain in the source language

What to manage in a style guide

• When to use loanwords and when to use established Korean terms
• Levels of politeness and style for each text type
• Punctuation, numbers, and symbol conventions
• Context-dependent action terms such as “누르다” and “클릭”

A useful distinction is that a glossary standardizes what to use, while a style guide standardizes how to decide.

Provide context for each text item

In addition to prompts and glossaries, provide the page name, UI element type such as heading, button, or link, display location, action target, character limit, surrounding copy, and screenshots for each text item. For example, you cannot choose the right translation of “click” without knowing the action target. AI needs not only the criteria for making a decision but also the context required to apply them.

Classify review findings with MQM categories to drive improvement

Multidimensional Quality Metrics (MQM) is an evaluation framework for organizing quality issues in human, machine, and AI translation by type and severity. Because this project involved website translation, we selected categories that we considered particularly important for websites: Accuracy, Terminology, Style, Audience appropriateness, and Design and markup.

Using MQM as a shared classification system helps teams organize issues within an internationally recognized framework instead of relying solely on individual judgment, supporting continuous improvement.

• Accuracy: Does the translation accurately reflect the source without omissions or unnecessary additions?
• Terminology: Are product names, feature names, and action terms consistent across pages?
• Style / Audience appropriateness: Does the Korean sound natural and suit the target audience?
• Design and markup: Does the wording reflect the function of buttons and menus?
• Accuracy: Are numbers, proper nouns, prices, and contract terms correct?
• Design and markup: Is any text cut off or difficult to read in the actual interface?

A workflow for translating websites into Korean

Step 1: Prepare the source text and on-screen context

Prepare not only the text to be translated but also the page name, UI element type such as heading, button, or error message, character limits, and screenshots. Designate Japanese as the source language. If reviewed translations are available in other languages, use them as supporting information to help resolve ambiguity.

Step 2: Apply prompts, glossaries, and style guides during AI translation

Apply site-wide translation rules and approved terminology from the initial draft stage. If existing pages are available, refer to their wording as well so that the same feature is not given multiple translations.

Step 3: Review using MQM categories

Review the translation against the MQM categories described above, as well as the glossary and style guide. Record the category, severity, and reason for each revision so the findings can feed into future translation and review cycles.

Step 4: Check the live interface and SEO elements

Place the translation in the interface and check line breaks, button widths, clipped text, and any untranslated content. Also review elements that affect how the Korean page appears in search, including the page title, meta description, headings, and internal links.

Step 5: Feed revisions back into your translation assets

Incorporate recurring corrections identified during review into the prompt, glossary, and style guide. When decisions from native speakers, linguists, marketers, and language directors are stored as translation assets together with MQM categories and the reasons for each change, expertise that was previously confined to individuals can be reused by AI and the wider team. This reduces the effort of correcting the same issues after every update and continually improves quality across the website.

Conclusion: Managing a natural, consistent Korean website efficiently

Translation for reading the content of a foreign-language website requires different quality controls from translation for publishing and maintaining a Korean website. For a public website, it is important to check not only accuracy but also natural Korean, terminology consistency, UI context, and readability in the live interface.
