Your page has versions for different languages, but you haven't specified a default page for users whose language doesn't match any of them. The `x-default` `hreflang` attribute does just that—it's a catch-all that tells search engines where to send users who don't fit into your specified language groups. It's a best practice for international SEO.
A set of `hreflang` tags without a fallback `x-default` version.
Add an `x-default` `hreflang` tag that points to a language-selector page or the most common language version of your page.
<link rel="alternate" hreflang="en" href="https://example.com/en/page">
<link rel="alternate" hreflang="de" href="https://example.com/de/page">
<link rel="alternate" hreflang="x-default" href="https://example.com/en/page">The `x-default` tag gives you control over what users see when their language doesn't match your offerings, improving their experience and giving search engines a clear directive. Learn more from Google's guide on using x-default.
