What this tool does

Hreflang tags tell search engines which URL to show for each language or region, but a single duplicated locale code or a URL missing its scheme can quietly break the whole cluster. This tool takes a list of locale and URL pairs, one per line, generates the corresponding link tags, and flags duplicate locale codes, rows it could not parse, and URLs without an http or https scheme.

How to use it

  1. Enter one row per line as a locale code followed by a URL, such as "es https://example.com/es/".
  2. Add an x-default row if the site has a language-neutral fallback page.
  3. Copy the generated tags and review the issues list for anything that needs fixing.

Privacy

Frequently asked questions

Is my data sent anywhere?
No. Parsing and tag generation happen in JavaScript running in your browser tab.
Do hreflang tags need to be reciprocal?
Yes. Search engines expect every URL in a cluster to link back to every other URL, including itself; this tool does not check other pages, so keep the same row set on each page's version of the tags.
What counts as a duplicate locale code?
Two rows using the same locale code regardless of letter case, such as ES and es, which would otherwise produce two conflicting hreflang entries.
