Frequently asked questions

What do hreflang tags do?

They tell search engines which URL serves which language or region (en-GB, de, pt-BR …), so users get the right version and the variants don’t compete with each other as duplicate content.

Do I need an x-default?

Strongly recommended. x-default names the fallback URL for visitors who match none of your declared locales — typically your language selector or your primary version. This tool flags pages that declare alternates without one.

My hreflang lives in the sitemap or HTTP headers — why is nothing found?

This tool reads <link> tags in the page HTML, which is the most common implementation. Hreflang declared in an XML sitemap or HTTP headers is equally valid but not visible here.
