hreflang Checker
Score whether crawlers can map language versions from unique BCP 47 links — not a ranking trick.
What this tool gives you
Check hreflang
Fetch a public page or paste the head. The checker scores locale-cluster hygiene — not ranking folklore.
What this checker looks for
hreflang names the other language versions of one URL. It does not make ChatGPT cite you.
rel=alternate
Each locale needs its own absolute URL.
BCP 47
Use en, es-MX or x-default — never en_US.
HTTPS href
Relative /es/ paths fail in the cluster.
Self link
The current URL must appear in its own set.
x-default
Point unmatched languages at a fallback URL.
html lang
Page language should match one hreflang code.
How to use the checker
Only annotate real language versions. Fake /es copies create a broken cluster.
Check the live page
Fetch the public URL or paste the head from view-source.
Name every locale
One absolute https URL per language, including this page and x-default.
Recheck after CMS changes
Plugins overwrite hreflang silently. Re-run after launches.
What healthy hreflang usually includes
Unique BCP 47 codes. Absolute HTTPS hrefs. Self-reference. Return links. x-default for unmatched languages.
| Part | Job | Default for public sites |

| BCP 47 code | Name the language | en, es-MX, pt-BR — not en_US |
| href | Point at that locale | Absolute https, no relative paths |
| Self-reference | Include this URL | Every member lists itself |
| x-default | Catch unmatched languages | Fallback language URL |
| html lang | Name this document | Match one hreflang code |

hreflang FAQs
Does hreflang make ChatGPT cite my page?
No. hreflang tells search engines which language URL to show. Citations still depend on crawl access, answer-ready content and corroboration.
When do I need hreflang?
Only when the same page exists in more than one language or locale. A single English site does not need a cluster. Do not invent /es copies just to add tags.
Should every URL include itself?
Yes. Each language URL should list every member of the cluster, including itself, with absolute https hrefs and matching return links.
