Missing X-Default Hreflang

What This Means

The page has hreflang language tags for specific locales (e.g., en-us, en-gb, de) but does not include an hreflang="x-default" tag. The x-default tag designates the page to show to users in regions not matched by the other language tags.

Why It Matters for SEO

Without x-default, users arriving from countries not covered by any specific hreflang tag see whichever regional variant Google selects by default. With x-default, you explicitly designate a fallback — typically the global English version or a language-selection page. This is particularly important for international sites covering most but not all global markets.

What the Platform Checks

For pages with multiple hreflang tags, the platform checks for the presence of an hreflang="x-default" tag. Fires when none is found.

How to Fix It

• Add an hreflang="x-default" tag pointing to the page you want users from undefined regions to see:

<link rel="alternate" hreflang="x-default" href="https://yourdomain.com/international-page/">

• The x-default URL is typically the global version, a language chooser page, or the English version.
• Add the x-default tag to all pages in the hreflang set — consistency across the set is required.
