You can help Google determine the language correctly by using a single language for content and navigation on each page, and by avoiding side-by-side translations.
Keep the content for each language on separate URLs.
Many websites serve users from around the world with content translated or targeted to users in a certain region. Google uses the rel="alternate" hreflang="x" attributes to serve the correct language or regional URL in Search results.
