Translate a Korean SaaS Landing Page With SEO Tags Intact
Proxylang translates a Korean SaaS landing page into English, Japanese and Chinese with one script tag, and from the Lite plan up it gives each language its own URL with hreflang tags for search engines. Your hosting, analytics and A/B tests stay as they are, and there is no second site to manage.
How Proxylang handles a Korean landing page
You add one script tag and the translation runs in the visitor's browser. The site stays on its own hosting, so nothing moves and your analytics and A/B tests keep working. There are no duplicate pages to maintain.
Proxylang supports 77 languages, so English, Japanese and Chinese are covered, and setup takes about 60 seconds. If you build with React, Next.js, Vue or Nuxt, the same script tag applies.
Per-language URLs, hreflang and indexing
Per-language URLs with hreflang tags for search engines come with every plan from Lite up. That is what lets Google tell your Korean, English, Japanese and Chinese pages apart.
If your site is built with code, hybrid SEO/GEO mode goes further. You add a few DNS records at your registrar, and Google, Bing, Naver, ChatGPT and Perplexity get fully translated per-language pages. Visitors keep using the script tag. Hybrid mode starts on Lite, which indexes 1 language. Start indexes 3, which fits English, Japanese and Chinese.
Translation quality for Korean and Japanese
Proxylang scored 4.72 out of 5 in a 280-sentence blind test, ahead of DeepL at 4.61 and Google Translate at 4.20. The test was re-scored on 2026-10-18 by Claude Opus 5.5 and GPT-5.6 Terra Pro. For Korean to Japanese, Proxylang scored 4.69 against Google's 3.10.
Links, bold and italic text inside a sentence are translated as one sentence and moved to the right place for Japanese and Korean word order. A glossary and never-translate lists keep product names and feature terms consistent.
Fixing and checking translations
The Live Editor lets you click any translated sentence on the live site and fix it. You can also invite proofreaders. Proxylang also re-checks live translations against the rest of the site and your glossary and fixes lines that read wrong. That is free on every plan and never overwrites your edits.
