Translating your store
To translate your storefront content (i.e. content that you add to the store), you will need to use an app. The default Shopify Translate & Adapt app is a convenient option, allowing you to seamlessly translate your store into two languages for free. Additional translations will incur charges.
Alternatively, there are plenty of third-party apps on the Shopify App Store that offer content translation services, each with its unique process.
To begin, choose what languages you want to add to your store. Then utilize the app to do the translations.
Step 1: In your Shopify admin, go to Settings.
Step 2: Click Languages.
Step 3: Click Add Languages then select a language.
Step 4: Click Add to add the unpublished language to your Shopify admin.
Step 5: Using your translation app, follow the steps to translate your store's content. Clicking the Translate should provide a list of available translation apps.
Step 6: Preview and Publish your new language/s.
If you only have one language available then customers will see this by default.
If you have multiple languages available then customers will then be able to select a language. However, please ensure you have enabled the language selector option via your Theme Editor. For detailed steps on enabling this, scroll down to the next section.
Enabling the language selector
To allow your customers to change the language of your store, you need to enable the language selector option within your theme:
Step 1: Within your Shopify admin, go to Online Store > Themes.
Step 2: Go to your selected theme and select Customize to open the Theme Editor.
Step 3: Click the Header section.
Step 4: Scroll down to the Localization section and enable Show language selector.
Step 5: Save your changes.
