I Wrote 1 Korean Post, Published It in 4 Languages Simultaneously, and My Traffic Quadrupled

I'll be honest with you. I used to think "translation is something professionals should handle." But now, when I write one post in Korean, it goes up in English, Japanese, Spanish, and Chinese all on the same day. By the time you finish reading this, you'll be able to do it yourself today. Seriously.

Step 1: You Need to Choose the Right AI Tool for Translation (Don't Just Blindly Use DeepL)

A lot of people give up after only using DeepL or Papago. Do you know why? These tools are great at "literal translation," but they fall short for content like blogs where tone and voice matter. If the translated text feels unnatural, readers will bounce, and Google SEO won't pick it up well either.

Here's the combination I actually use and recommend.

• ChatGPT (GPT-4o): Natural writing style translation with adjustable tone. Just add "translate this in a friendly blog tone" to your prompt.
• DeepL: Use it for a quick first draft, then refine it with GPT in a two-step process — this makes the workflow much more efficient.
• Claude: Great at maintaining context in long-form content, making it ideal for posts over 2,000 characters.

Here's what to do: Go to ChatGPT right now and copy this prompt.

"Translate the following Korean blog post into [English/Japanese/Spanish/Chinese]. Keep the tone friendly and conversational. Localize any technical terms so they read naturally for readers in that language."

This one prompt makes all the difference between a plain translation and one that people actually want to read.

Step 2: The Actual Workflow for Converting 1 Post into 4 Languages

At first, I was working on each language separately. That took me two hours. Now I finish in under 30 minutes. The key is locking in a fixed order and template.

Here's the order I follow.

• ① Finish the Korean original: Write the Korean post to completion first. The quality of your translation depends entirely on the quality of the source.
• ② Translate into English first: English serves as a reference point for the other translations, and it has the largest traffic potential. Polish the English version first.
• ③ Then Japanese, Chinese, and Spanish: You can feed all three into GPT at once. Just say "Translate the English post above into Japanese, Simplified Chinese, and Spanish respectively" and it'll come out in one go.
• ④ Optimize the title separately for each language: What drives clicks varies by language and audience. English titles perform well with numbers, while Japanese titles tend to do well in the "～する方法 (How to ~)" format.

Here's how to do it: Create language-specific tabs in Notion or Google Docs and paste content into the same structure every time. Once this routine becomes second nature, finishing in 30 minutes is absolutely doable.

Step 3: Where Should You Post So All 4 Languages Can Actually Be 'Discovered'?

If you work hard on translations and then post everything on a single blog, it defeats the purpose. Different languages belong on different platforms. Without knowing this, you'll do all the translation work and see no change in traffic.

• English: Medium, Substack, or a WordPress blog in English. This gets the best Google search traffic.
• Japanese: note.com (Japanese version), Ameba Blog. Japanese readers use note heavily.
• Chinese (Simplified): Breaking into Chinese domestic platforms directly is tough, so consider posting on WordPress or Medium to capture Google search traffic. Readers from Taiwan and Singapore are also a bigger source of traffic than you might expect.
• Spanish: Medium with Spanish-language tags, or use a WordPress multilingual plugin (WPML, Polylang).

Here's what to do: Trying to manage all 4 platforms from the start will burn you out. Start with just English + Japanese. Even with just these two languages, your potential readership is in the hundreds of millions. Once you've found your footing, then expand to more languages.

Step 4: The Only Things You Need to Watch Out for to Avoid Ruining Your Translated Post's SEO

Translated posts can sometimes be penalized in SEO. There are two main reasons: duplicate content issues and missing keyword optimization. But these are actually simpler to fix than you'd think.

• Set up hreflang tags: If you're on WordPress, plugins like AIOSEO or Yoast handle this automatically. It's a tag that tells Google "this page is the English version of the Korean original." Without it, Google may flag your content as duplicate.
• Research keywords separately for each language: If "AI 번역 (AI translation)" is your keyword in Korean, the English equivalent might not be "AI translation tool" — "machine translation blog" could have higher search volume. Spend just 10 minutes researching language-specific keywords using Google Keyword Planner or Ubersuggest.
• Translate meta descriptions and include keywords: Many people translate the body but forget the meta description. Just ask GPT: "Write a meta description for this post in each language, within 160 characters."
• Write image alt text in the target language too: It may seem minor, but having image alt text in the correct language can bring in traffic from image search as well.

Here's how to do it: After finishing your translation, ask GPT: "Give me the main keywords, meta description, and image alt text suggestions for this post in [target language]." That one prompt lets you cover all your SEO bases at once.

The First Action You Can Take Right Now

Don't overthink it. You only need to do one thing today.

Pick the Korean post you're most proud of, paste it into ChatGPT, and request an English translation. Use the prompt I gave you above, exactly as written. Posting the translated piece on Medium will take less than 10 minutes.

You don't need to perfectly execute all 4 languages across 4 platforms from day one. Your goal for today is to post one English translation on Medium.** You can figure out the rest after that. That's how I started too — and now, publishing in 4 languages every week runs on autopilot.

You'll see once you try it. It's a lot easier than you think.
