In-depth guide
Hreflang annotations tell search engines which language and region each version of a page targets, so a French user sees the French URL and a UK user sees the GBP-priced one. They prevent the wrong locale from ranking and reduce duplicate-content confusion across translated pages. This tool builds the reciprocal tag set in your browser.
Each tag uses an ISO 639-1 language code, optionally plus an ISO 3166-1 region: en, en-GB, es-MX. The special value x-default marks the fallback page for users whose language you do not explicitly target. Region without language (GB alone) is invalid.
x-default entry for the global fallback.<head> of every page in the group.Hreflang only works when the references are mutual: if the English page lists the German one, the German page must list the English one back, and both must list themselves. A missing return link is the single most common reason hreflang is ignored. You can also place these as XML sitemap alternates instead of head tags — adapt the URLs accordingly.
en-GB vs en-US only if the pages genuinely differ.Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.
Yes. Add x-default as the language code to mark the fallback page for users whose language you do not explicitly target.
Yes. Hreflang must be reciprocal — every page in the group must list every locale including itself. A missing return link is the most common reason hreflang is ignored.
Yes. The output is HTML link-tag format, but the same URL and language values can be placed as alternate links in an XML sitemap.
Use an ISO 639-1 language code, optionally with an ISO 3166-1 region: en, en-GB, es-MX. A region on its own (like GB) is invalid — language is always required.
They must agree. Each language version should canonicalise to itself; pointing hreflang at one URL while canonicalising to a different one sends contradictory signals.
Use Google Search Console's International Targeting report, which flags missing return tags and unknown language codes after the pages are crawled.
