Why I Built SEO Content in 4 Languages Instead of Doubling Down on English
I launched my first SaaS product in English only. Six months in, I had zero organic traffic. My Ahrefs dashboard was a graveyard. I realized my mistake wasn't the product—it was the market. I was competing against content mills and established players in saturated English niches.
Around month seven, I noticed something: my GitHub readme had more engagement from non-English countries than my landing page. So I did what any desperate indie hacker would do—I went contrarian. Instead of hiring a marketer, I decided to write in the languages where I could actually compete: Korean (my native language), Japanese, simplified Chinese, and Portuguese.
Looking back, this decision gave me my first $1 MRR (micro-monetization, but still). More importantly, it taught me how to think about SEO as a solo founder without a huge budget.
The Language Selection Framework (Not Random)
I didn't pick four languages from a hat. Here's what I actually did:
Search volume vs. competition ratio. I used SEMrush's free tier and Ahrefs' free limited reports to check keyword difficulty in different regions. Korean tech searches had maybe 30-40% of English volume but 10% of the competition. That's a 3-4x advantage. Japanese was similar. Portuguese SEO was wide open because most content creators focus on English and Mandarin.
Personal credibility. I'm fluent in Korean and Japanese. I can fake decent Portuguese with tools, but I hired a native speaker for review ($15/article). For Chinese, I brought in a co-founder friend (unpaid, equity split). The point: don't write in a language you'll butcher. Readers know.
Monetization accessibility. I checked which regions had actual payment methods integrated with my payment processor (Stripe + local alternatives). Korean and Japanese users could pay directly. Portuguese Brasil had strong purchasing power. China was trickier, so I deprioritized initially.
The framework was simple: Volume × Credibility × Monetization Potential = Language Choice
18 Articles: The Content Strategy That Actually Generated $1
Here's my honest breakdown of the 18 pieces:
- Korean (7 articles): Highly specific product tutorials, comparison guides, and "how to avoid X mistake" content. Average search volume: 200-400/month per article. I kept these tight—1,500 words max because Korean readers skim.
- Japanese (5 articles): Similar structure, slightly longer (2,000 words). Japanese searchers trust detailed content. I prioritized evergreen explainer pieces.
- Portuguese (4 articles): Blog posts targeting Brazilian developers. Lower volume (100-200/month) but higher conversion. The audience trusted English product docs less.
- Chinese (2 articles): Experimental. I syndicated through a local Chinese dev community forum, not direct ranking.
I didn't write 18 random articles. Each piece targeted a specific keyword with 50+ monthly searches, under 30 keyword difficulty (on a 0-100 scale). I used:
- Google Search Console (free, critical data)
- Ubersuggest free tier (keyword ideas, 3 free searches/day)
- Manual searches (what do my users actually ask?)
The 18 articles took three months. Roughly 8-10 hours per language per week, mostly evenings. I reused about 40% of content structure across languages, adapting the examples. This wasn't lazy—it was efficient.
The $1 MRR Breakthrough (And Why It Felt Like $1,000)
In month four of publishing these articles, I got my first paid signup from Japan. $8/month. Then a Korean user. $5/month. Then nothing for two weeks.
By the end of month five, I had three paying customers across these regions. Not enough to quit my job, but enough to validate the hypothesis: non-English niches convert better even with smaller search volume.
The math: 50 organic visitors/month from Korean SEO (small!) converted at 6% (one signup per month from this cohort). English SEO was getting 200+ visitors with 0% conversion. Quality beats volume when you're unknown.
How did I know what worked? My analytics stack:
- Plausible (privacy-first, language-aware tracking): $9/month
- Google Analytics 4 (free, but I prefer Plausible for this use case)
- Stripe Dashboard (which country did each signup come from)
I can see exactly that 68% of my revenue came from Japan/Korea traffic, not English. The other 32% came from a Reddit thread I posted on r/Japan. (SEO alone wasn't the whole story.)
What Actually Moved the Needle
Three things changed my trajectory:
1. Ranking posts quickly. By the third month, I had 12 articles in Google's top 100 for their target keywords. Six months in, five articles cracked top 20. That's not "overnight SEO success"—that's the grind. But in smaller languages, the grind is shorter.
2. Community involvement. I joined Japanese and Korean tech forums (Hacker News JP, Qiita, Korean dev Slack communities), posted my articles in context, not as pure promotion. Generated maybe 25% of my organic traffic. Google ranking generated 75%.
3. Interlinking aggressively. Every Korean article linked to related Korean articles. Same for Portuguese. This created a content hub effect. Bounce rate dropped 15%, average session duration increased. Google noticed.
The Brutal Honesty: This Strategy Has Limits
$1 MRR means I'm not quitting my day job. I'm not buying ramen with profits. Here's what I learned won't work at scale with this approach:
- Paid ads: I tried Google Ads in Japanese. Cost per click was $0.15-0.25. Conversion was 2%. Math doesn't work without serious volume.
- Content production: 18 articles took three months solo. To hit $100 MRR, I'd likely need 80-100 pieces, which isn't sustainable alone.
- Competitive pressure: English-heavy markets will always have better content. Non-English markets are easier entry points, but growth is capped by market size.
What's working now (month seven):
- Email list: 47 subscribers from organic. These convert at 12%.
- Repeat traffic: 35% of new users are returning (per GA4). In month one, it was 8%. Trust compounds.
- Translation ROI: Each piece I translate to a new language takes 6-8 hours, generates $0.20-0.30/month. Slow, but positive unit economics.
The Real Takeaway for Solo Founders
The Internet rewards focus. When everyone writes in English about the same topic, you lose. When you pick an underserved language and write better-than-average content in that language, you win immediately.
This isn't about speaking four languages (though it helps). It's about thinking in niches. My four-language strategy worked because I didn't dilute effort—I went deep in each language with specific personas.
If you're a solo founder with SEO questions, or you want to see how I've organized these 18 articles and the exact traffic breakdowns per language, I've documented the full case study at https://sajuapp.app/?utm_source=devto&utm_medium=social&utm_campaign=longform_weekly. I'm also sharing the keyword research spreadsheet and the interlinking strategy that cut through the noise. Building in public means sharing the wins and the $1/month reality—both matter.
