Hreflang Tag Generator

Hreflang Tag Generator: hreflang link tags, sitemap entries and headers, validated. Input: Values you enter. Output: Results shown on the page and text to copy. Privacy: Runs in your browser: inputs and files stay on your device and are not uploaded.

How to generate hreflang tags

1. Add one row per language or country version of the page: the hreflang code (such as en, en-GB, de or pt-BR) and the full URL of that version.
2. Keep x-default on and point it at your language selector or the version for everyone else.
3. Choose the output: <link> tags for the page head, entries for an XML sitemap, or an HTTP Link header for PDFs and other non-HTML files.
4. Fix any warnings, then add the same complete set to every language version.

How hreflang works

hreflang tells Google and Yandex which language or regional version of a page to show to each user, so a searcher in Germany sees your German page and one in Mexico sees the Latin American Spanish page. It also stops near-identical versions (for example US and UK English) from competing with each other as duplicates.

The rules are strict, and mistakes are common:

• Codes are an ISO 639-1 language, optionally followed by an ISO 3166-1 region: en-GB, not en-UK. A region alone, such as GB, is invalid.
• Every version must link to every other version and to itself (return links). If page A lists B but B does not list A, Google ignores the pair.
• Use absolute URLs of canonical, indexable pages.
• Use one method per page: HTML tags, sitemap or HTTP headers.

The validator catches invalid codes and suggests fixes, such as en_us to en-US. Everything runs in your browser.
