Give each important localized version a clear URL and reviewed content. Translate meaning, examples, units, and policies rather than only individual words.
Choose an architecture
Language folders or locale subdomains can both work. Keep the chosen URLs stable, avoid mixing unrelated languages on one page, and make navigation between versions clear.
Use language annotations correctly
Google documents supported language and regional annotations in its localized-versions guide. Check reciprocal alternates and canonical relationships for your actual pages. These search annotations do not establish a universal behavior for every AI provider.
Maintain discovery resources
A sitemap can list the localized pages. The llms.txt proposal permits content guides scoped to a host or path, but publishing one does not prove a measured visibility improvement for a language. On answer.cloud, use the platform publishing workflow for generated resources.
Test representative questions in each important language and have a fluent reviewer check facts and terminology. See multilingual chat.
