SEO that works in the US market fails in Europe. Backlink rules differ completely across markets.

I helped a client expand its product from the US market to Germany and Japan. The same SEO strategy—directory submissions, guest posts, content marketing—performed great in the US but was almost useless in Germany and Japan. Each market’s backlink ecosystem is completely different.

Many founders operate under an implicit assumption: SEO strategies are universal. A strategy that works in the US will work in other countries as well.

I used to think the same—until I helped a client with international SEO and discovered that this assumption is completely wrong.

The same strategy, the same execution quality, the same time investment—produce vastly different results across markets.

This article shares my real‑world experience in three markets (US, Germany, Japan) and explains how backlink rules differ.

Three markets, three realities

Client background: B2B SaaS tool, launched in the US in 2024, started expanding to Germany and Japan in 2025.

Our strategy was identical in all three markets:

• Directory submissions (30 directories per market)
  
• Guest posts (5 per market)
  
• Content marketing (10 blog posts per market)
  
• Community participation (Reddit / Xing / industry forums)

Results after 6 months:

The same strategy worked best in the US, less so in Germany, and barely at all in Japan.

Why?

United States: the most mature SEO ecosystem

The US has the most mature SEO ecosystem worldwide. This means:

Advantages

• The largest number of high‑quality directories (G2, Capterra, Product Hunt, etc.) are US‑centric
  
• Blogs and media are very receptive to guest posts
  
• English content enjoys global reach
  
• SEO tools and data are the most abundant

Challenges

• Competition is fierce; almost every industry has many players doing SEO
  
• Users are immune to “SEO content”—they can spot articles written just for rankings
  
• Google’s algorithm updates land in the US market first

Suitable backlink strategies

• Directory submissions (many high‑DR directories with high acceptance rates)
  
• Guest posts (high acceptance, many blogs accept submissions)
  
• Content marketing (English content can be globally covered)
  
• Community participation (Reddit, Hacker News, Indie Hackers)

Germany: higher quality standards, slower trust building

Germany has several unique characteristics:

Language barrier: German users trust German‑language content more. English content ranks far lower in Germany. You must localize—not just translate, but rewrite using German phrasing habits.

Higher trust threshold: German users and Google Germany are slower to trust “new brands.” You need more social proof—coverage in German media, German user reviews, endorsements from German industry associations.

Different directory ecosystem: The US mainstream directories (G2, Capterra) have some presence in Germany, but there are also uniquely German directories—SaaS Germany directories, industry‑association directories, German business registration platforms. Their DR may be modest (30‑50) but they carry strong SEO weight locally.

Low guest‑post acceptance: German blogs and media are much less receptive to guest posts than US outlets. They care more about the author’s “German background”—are you a German company? Do you have German customers? Do you have industry contacts in Germany?

Suitable backlink strategies

• Prioritize German‑language content (don’t try to cover Germany with English)
  
• German local directories (industry associations, business registries, German SaaS directories)
  
• German media relations (requires local PR capability)
  
• German user reviews (encourage German customers to leave reviews on German platforms)

Japan: a completely different rule set

Japan is the most “different” SEO ecosystem I’ve encountered.

Very high language barrier: Japanese and English content belong to completely separate index worlds. SEO done in English has almost no impact in Japan.

Totally different directory ecosystem: US mainstream directories have virtually no presence in Japan. Japan has its own directories—Japanese business directories (e.g., EPARK, じゃらん), Japanese SaaS comparison sites, Japanese industry media. Their interfaces, user habits, and submission processes differ entirely from the US.

Guest posts almost nonexistent: Japanese blog culture does not accept “guest contributions” the way the US does. Industry content is mostly produced by media and industry associations; individual blogs have far less influence.

Google Japan vs. Yahoo Japan: Yahoo Japan still holds about 20 % of the search market. Therefore, Japanese SEO must consider both Google and Yahoo ranking factors.

Suitable backlink strategies

• Japanese‑language content is a prerequisite (no shortcuts)
  
• Japanese local media and PR (requires a local network)
  
• Japanese business directories (submit to Japanese industry directories)
  
• Yahoo Japan optimization (cannot ignore Yahoo’s search share)

Characteristics of other markets

Beyond the US, Germany, and Japan, I’ve worked with several other markets:

United Kingdom: Similar to the US but with its own directory ecosystem (UK‑specific business directories). UK users have a slight aversion to “American‑accent” content.

France: French content is mandatory. France’s SEO ecosystem is more closed than Germany’s—French media and blogs tend to cite French companies.

South Korea: Naver dominates with over 60 % market share; Google is not dominant. Korean SEO must optimize for both Naver and Google.

Brazil: Portuguese content is mandatory. Brazil’s directory ecosystem is still developing; high‑quality directories are limited. However, Brazilian social media (e.g., Instagram) has a strong indirect impact on SEO.

India: English works well because many Indian users are English‑speaking. Yet the directory quality varies widely—many low‑quality directories require careful selection.

International SEO backlink strategy framework

If you’re doing international SEO, here’s a generic framework:

Step 1: Understand the target market’s search ecosystem

• Which search engine dominates? (Google? Yahoo? Naver? Baidu?)
  
• What language do users search in?
  
• Which local high‑quality directories and platforms exist?

Step 2: Produce localized content

• Not translation—rewrite using the local language and idioms
  
• Consider cultural differences and user habits
  
• Use local keyword research tools (not just Ahrefs, but local tools)

Step 3: Acquire local backlinks

• Submit to local directories
  
• Reach out to local media and blogs
  
• Build presence in local communities

Step 4: Monitor local rankings

• Check rankings on the local Google version (google.de, google.co.jp)
  
• Don’t rely solely on global rankings
  
• Consider local search engines (Yahoo Japan, Naver, Yandex)

Practical time‑allocation suggestion

If you’re working on the US plus one international market, a suggested split:

Key principle: Content creation for the international market should take a larger share because localized content is the foundation of international SEO—without it, all other backlink tactics are ineffective.

Bottom line

SEO is not globally universal. It is highly localized.

Before entering a new market, first understand its search ecosystem, language requirements, directory culture, and user habits. Don’t assume “what works in the US works elsewhere.”

The core of international SEO is not “translate your content,” but “understand your market.”

Backlink strategies follow the same logic. Each market has its own high‑quality directories, media ecosystem, and community culture. You need to learn and adapt market by market.

It’s far more challenging than single‑market SEO, but when you get it right, the payoff is much larger.
