THE SHORT ANSWER
A bilingual website needs more than a language switch. German and English visitors each need understandable content, appropriate examples and a complete journey through to an enquiry. Search systems need consistent URLs and clear relationships between equivalent language versions. Effective localisation combines editorial and technical work rather than adding translation at the end of the project.

Decide which markets each version should serve
English is a language rather than one uniform target market. Decide whether you want to reach internationally operating companies in general or a specific region. German likewise covers markets with differences across Germany, Austria and Switzerland. Not every variation justifies a separate country version. A distinct editorial approach becomes useful when offers, terminology or practical conditions materially differ. Record the target audience and applicable services so that translation does not accidentally promise a different offer. That decision should precede the technical implementation.

Give each language version a dependable URL
A clear structure with language-specific URLs makes content directly accessible and shareable. Whether subdirectories or another architecture are appropriate depends on the project. Language directories are manageable for many smaller websites. The language switch should lead to the equivalent page wherever possible, rather than always sending readers to the homepage. Avoid forced automatic redirects that make a preferred language hard to access. Also check that shared links lead to understandable pages regardless of cookies or a visitor’s previous language selection.
Understand hreflang as a relationship between variants
hreflang identifies equivalent language or regional versions for search systems. Each participating page should reference the relevant alternatives, including itself, and return relationships need to be consistent. Use fully qualified URLs and valid language codes. Google supports HTML, HTTP header and sitemap implementations; one consistent method is sufficient. hreflang does not replace translation or a useful URL structure. Do not connect arbitrary posts merely because they discuss the same general subject. The relationship should represent a genuine equivalent version of the page.
Keep canonical signals and language relationships consistent
Translated pages are separate language versions, so avoid automatically pointing every canonical reference to the German URL. Review canonical signals, internal links and hreflang together so that they do not describe conflicting structures. Pay particular attention to obsolete destinations after redirects or renaming. Correct navigation does not prove metadata has also been updated. Test complete page pairs and their actual delivery. Unusual regional variations may require a more detailed architectural review before implementation, especially when content and commercial conditions differ substantially between versions.
Localise meaning rather than individual words
A German service description may need a different sentence structure or an additional example in English. Review terminology, units, date formats and calls to action. Translate metadata, image descriptions, forms and confirmation messages as well. An English contact page with German validation errors can undermine confidence just before an enquiry. Machine translation can provide a draft, but technical claims still need review. Comparisons, service limitations and contractual references deserve particular attention so both language versions provide equally dependable information rather than superficially similar wording.
Measure and maintain each version independently
Monitor searches and user journeys by language and relevant market. An English page need not attract the same terms or level of demand as its German equivalent. When updating an article, flag its translation for review too. Check new URLs for appropriate links and working language switches. Define how untranslated articles should be handled rather than sending visitors to a different piece of content under the appearance of a translation. A smaller, maintained bilingual collection is more useful than a large library with unclear translation status and inconsistent promises.

Do we need both hreflang and an HTML lang attribute?
They serve different purposes. Use the correct document language and suitable hreflang relationships between equivalent variants.
Should the English switch always lead to the homepage?
Prefer the equivalent page. When no translation exists, explain the available options clearly.
Can the English version use different examples?
Yes, if it serves the same subject and purpose. Technical claims and service boundaries must remain consistent.
How can I put “Decide which markets each version should serve” into practice?
English is a language rather than one uniform target market. Decide whether you want to reach internationally operating companies in general or a specific region. German likewise covers markets with differences across Germany, Austria and Switzerland.
