International SEO – visible in every market you sell in.
Multilingual and international websites are one of the most common SEO problem areas: hreflang errors, duplicate content between languages, faulty market-targeting setups. We build your international SEO so that every market gets its own visibility.
- hreflang setup
- Mirrored URL structure
- Localization, not translation
- x-default compliant
International SEO ensures that every language and country version of your website ranks in the right market, through correct hreflang markup, clean country targeting and localized rather than merely translated content.
The right country, the right language
With a clean hreflang setup and mirrored URL structure, Google shows each region the right version – without duplicate-content risk.
What the tags look like for DE/EN/x-default
<!-- Add to every page version inside <head> --> <link rel="alternate" hreflang="de" href="https://loomup.io/leistungen/seo/"> <link rel="alternate" hreflang="en" href="https://loomup.io/en/services/seo/"> <link rel="alternate" hreflang="x-default" href="https://loomup.io/leistungen/seo/"> // Plus optionally in the XML sitemap per URL: <xhtml:link rel="alternate" hreflang="de" href="https://loomup.io/leistungen/seo/"/>
Which URL structure for which market
| Criterion | Subdirectory (/en/) | Subdomain (en.) | ccTLD (.com) |
|---|---|---|---|
| Domain authority inheritance | Full | Partial | None |
| Setup effort | Low | Medium | High |
| Hosting cost | 1× | 1–2× | n× |
| Local targeting in Search Console | Per country separately | Per subdomain | Implicit |
| Market trust (local) | Medium | Medium | Very high |
| Ideal for | 2–4 languages, DE/EN | Tech brands, subdomain setup | Global enterprises, market strategy |
What we watch for on every project
hreflang & market targeting
Correct hreflang tags for every language and market combination. x-default fallback. Search Console market setting per property.
Mirrored URL structure
Recommendation: language segment in the path (/en/), not a subdomain. Every German URL has its counterpart in every target language at the same depth.
Localization, not translation
Word-for-word translations fail on search intent. We localize: terms, examples, units of measure and tone adapted to each market.
The key questions, answered briefly
What does hreflang do?
hreflang tells Google which language or country version of a page applies to which users. Implemented correctly, it stops versions from cannibalizing one another and ensures that, for example, German users see the DE page and British users the EN-GB page.
Is a translation enough for other markets?
No. Pure translation ignores local search terms, competition and cultural expectations. Successful international SEO localizes keywords, content and examples per market, otherwise the page won't rank in the target country.
The typical hreflang mistakes, and how to avoid them
hreflang is powerful but error-prone. These are the mistakes we see most often:
x-default for markets not covered.Does every country need a completely separate site?
A dedicated, localized version per language/market, yes, but not necessarily a separate domain. What matters is that content is genuinely localized (keywords, examples, tone) and correctly mapped via hreflang. Pure language duplicates without local adaptation won't rank in the target market, more on that under multilingual content.
Frequently asked questions
Subdomain, subdirectory or cc-TLD, which is better?
For most mid-sized companies we recommend a subdirectory (loomup.io/en/), as it consolidates domain authority, is cheaper to maintain and is sufficient for DE/EN. cc-TLDs (loomup.de, loomup.com) only make sense if you run a separate marketing and local strategy per market.
How many languages can a website sensibly serve?
Up to 3–4 languages with a standard setup; beyond that, a dedicated localization system pays off. Important: two languages done really well beats eight done half-heartedly.
Do you handle the translations?
We localize, which goes beyond mere translation. We work with native-speaking editors and check search intent and terminology in the target market.
