Hreflang Generator

When one page exists in several languages or regional variants, search engines cannot reliably guess which version belongs to which audience from visible text alone. Hreflang annotations solve that: link rel alternate elements in the page head, each pairing a code such as en, de or zh-TW with the full URL of that version, plus an optional x-default fallback. Crawlers read the whole cluster together and serve the German page to German searchers and the US page to US searchers instead of guessing.

How the tag builder mirrors the cluster

• 🌍 One-click quick-add for eleven frequent codes: en, zh, zh-TW, de, es, fr, hi, ja, ko, pt and ru, with free entry for the rest
• ⌨️ Live code check tinting the language box red when a code breaks the lowercase plus optional uppercase-region shape
• 🔗 One alternate line per language plus URL row, skipping blank rows so drafts never emit broken tags
• 🎯 Optional x-default fallback line appended after the language lines
• 📋 Copy to clipboard or download the block as hreflang-tags.html

Projects that reach for hreflang first

• 🌐 Launching a site in several languages and wiring the cluster before the first crawl
• ➕ Adding a new locale to a live multilingual site without orphaning the old versions
• 🔄 Fixing results that keep showing the wrong-language page to the wrong country

Reciprocity rules and honest limits

• ↩️ Every version must carry the full set pointing at all the others, so paste the block into each head, never just one
• 🔍 Hreflang is a strong hint, not a redirect: it guides which version ranks, never forcing a visitor elsewhere

Assembly happens entirely on your own device with no uploads and no stored copies, so unpublished URLs stay yours until you publish them.
