Do I have to show my website in all 19 languages?

By default, your website is available in 19 languages (English, Spanish (Spain), Spanish (Latin America), Portuguese (Portugal), Portuguese (Brazil), French (France), French (Canada), Italian, German, Polish, Russian, Korean, Turkish, Arabic, Vietnamese, Japanese, Chinese (Traditional), Chinese (Simplified), and Hebrew.).

However, you have the option to limit the language options that are visible to your clients. It's important to keep in mind that removing a language also means losing the SEO benefits that language provides to your website. This could result in people searching online in those languages being unable to find your website. Therefore, it's recommended to carefully consider the languages you choose to remove, and the potential impact on your online visibility.
