Yes, especially if you have a language selector, global homepage, or a fallback page for unmatched locales. x-default tells Google which URL to serve when no other hreflang matches the user's language/region settings. Without it, Google may choose arbitrarily for users outside your targeted locales.

What's the difference between hreflang="en" and hreflang="en-US"?

`en` targets English-speakers regardless of country. `en-US` targets English-speakers specifically in the US. Use the bare language code when content is the same for all regions (British and American readers get the same copy). Use language-region when you tailor content — pricing in local currency, region-specific products, legal language.

Must every version self-reference and cross-reference?

Yes. Each page must include hreflang tags for ALL versions including itself. If `/es/` lists `en-US` and `de` but forgets to list itself as `es`, Google ignores the cluster. This tool generates the complete bidirectional set automatically.
