Your website can be shown in English, Hindi, Gujarati, Marathi, Tamil and Arabic. How many you can switch on depends on your plan.
Turn a language on
Open Site settings → Languages, tick the languages you want and choose the default. Each page gets its own address per language (for example /hi/about), and search engines are told which version is which.
Translate your content
In the editor, switch the language at the top and edit text as usual. Use Rewrite → Translate for a first draft, then check it yourself or with someone fluent. Text you have not translated falls back to the default language.
Arabic
Arabic pages are laid out right-to-left automatically.
