The hreflang tag is required for multilingual SEO. If your website supports multiple languages, it is highly recommended to use it.

Generate tags like the following to help search engines quickly index different language versions of your page content:

<link rel="alternate" hreflang="" href="" />

Note: If your default language is not en, you need to replace the en in {{#if lang.isDefault}}en{{else}}{{ lang.name }} with your target language code. For example:

{{#if lang.isDefault}}fr{{else}}{{ lang.name }}
