For each language version, check that navigation, forms, privacy information, and core content are complete and understandable. Machine translation can introduce errors, especially in policy, financial, or safety instructions; have a fluent reviewer check important pages. Make language choices clear and avoid sending visitors to a version they cannot use.
Google’s AdSense approval guidance notes that most site content should be in a language AdSense supports. Verify the current supported-language information in Google’s official documentation before publishing. Search indexing for multilingual pages is a separate technical topic; use Google Search’s documentation for hreflang and international targeting.
Example: A site translates its menu but leaves the articles in English, creating a confusing mixed-language experience. Either complete the translation with quality review or clearly label the page language and destination.
Use SiteReadyScore to review public language versions and links. It cannot judge translation quality or support-language eligibility; verify both with human review and Google’s current list.
