Free Hreflang Tag Generator for International SEO
An hreflang tag generator builds the link tags that tell search engines which language and regional version of a page to show each user. Add your page versions below and get a complete, self-referencing tag set with x-default — subfolders, subdomains, and ccTLDs all handled.
Everything runs in your browser. Paste the output into the <head> of every version listed.
What does this tool generate?
This tool generates a complete hreflang tag set for any group of page versions — language-only codes like en and de, language-region pairs like en-us and en-gb, and an x-default fallback. It validates every code against the correct ISO 639-1 language and ISO 3166-1 region format, warns you about the classics (region-only codes, underscores instead of hyphens, "uk" instead of "gb"), and outputs both HTML link tags for your head section and an XML block for sitemap-based implementations. Because every URL is a full absolute URL, the same output works whether your site splits by subfolder (example.com/de/), subdomain (de.example.com), or ccTLD (example.de). The set is self-referencing by construction: paste the identical block into every version and the return-tag requirement is satisfied automatically.
How to use it (3 steps)
- Add each page version — its language (or language-region) code and its full URL.
- Keep x-default on and point it at your global page or language selector.
- Copy the tag block into the <head> of every listed version — the same block on all of them.
Why hreflang mistakes quietly cannibalize international rankings
Hreflang has the worst effort-to-error ratio in technical SEO: the concept takes a minute to explain and the implementation fails on sites of every size. The failure is silent — nothing breaks visually, but Google starts showing your US page to UK searchers, your English page outranks your German page in Germany, and your regional versions compete with each other as near-duplicates instead of reinforcing each other. Most implementations fail on one of three details: missing return tags (every version must reference every other version), missing self-references, or invalid codes like en-uk — the United Kingdom is gb, and this generator corrects that automatically. Getting it right consolidates your ranking signals per market and tells both search engines and AI assistants which version of your content is canonical for which audience. If you're expanding internationally, pair clean hreflang with entity markup from my Schema Markup Generator so each market version declares the same brand, and check the full picture with a free AI SEO audit — I've untangled hreflang on client sites across the US, UK, Australia, and India, and the audit will catch conflicts a generator can't.
FAQ
Hreflang tells search engines which language and regional version of a page to show each user, so your German visitors land on the German page and your US and UK visitors get the right English variant instead of competing duplicates.
Yes. Every page in the set must include an hreflang tag pointing to itself plus tags for every alternate. Each version also needs to reference all the others — missing return tags are the most common reason hreflang gets ignored.
x-default names the fallback page for users who match none of your language versions, typically your global homepage or a language selector. Google recommends it, and this generator includes it by default for exactly that reason.
Use language-only (en, de) when one version serves all speakers of that language. Add a region (en-us, en-gb) only when versions genuinely differ by country, like currency or spelling. Region-only codes are invalid — a language is always required.
Put the full set of link tags in the head of every page version, or deliver the same mapping through your XML sitemap or HTTP headers. Pick one method and stay consistent — mixing methods across pages invites conflicts.
