The usual failure in international SEO is a site competing against its own translations. Two language versions targeting the same audience, hreflang that points in one direction only, or a machine translation nobody proofread — each turns extra work into lost visibility.
What this covers
- choosing a URL architecture and committing to it
- hreflang across every equivalent page
- per-language canonical rules
- content adapted rather than translated word for word
- market-specific keyword research
Pick one architecture
Subdirectories, subdomains and country domains all work. Subdirectories are usually the pragmatic choice: they inherit the domain's existing authority and are far cheaper to operate than separate country domains.
What matters is choosing once and applying it consistently. This site uses /de/ for the German section, with English at the root and no trailing slashes anywhere, because the host normalises them.
hreflang, done correctly
Three rules cover most of it. Every page references itself as well as its alternates. The relationship is reciprocal — if A points at B, B must point back. And only genuine equivalents are paired.
That last one gets ignored constantly. An FAQ page and a guides hub are not equivalents, however tempting the symmetry. Pairing them tells search engines something untrue.
Use de rather than de-DE unless you genuinely target one country separately from other German-speaking markets.
Translation is not localisation
Search terms differ between markets in ways translation cannot capture. The literal translation of your best-performing English term may be something nobody in Germany types. Each language needs its own keyword research.
Beyond vocabulary, expectations differ: invoice payment in German e-commerce, formal address in German business writing, different assumptions about what a price includes.
Machine translation
Unreviewed machine output reads as unreviewed to customers and increasingly to search engines. It is acceptable as a first draft with a competent editor. It is not acceptable as a publication process.
FAQ
Should we redirect visitors by IP?
No. Offer a choice and remember it. Forced geo-redirects stop crawlers reaching versions they need to see, and irritate travellers.
Do we need a .de domain?
Not for ranking in Germany. A well-implemented subdirectory on an established domain generally performs at least as well.
Can one page target Germany and Austria?
Usually yes with de. Split only when the content genuinely differs.
