Free international SEO tool
Check your language and country versions in one go: do visitors and Googlebot reach every version, is each version really in its own language, and does every page exist in every language? Enter your website, one page or a sitemap.
What this check can't tell you
This tool tests how your language versions are built and connected. It can't see how they perform in each market.
That is what my International & Multilingual SEO service is for: an expert review of your international set-up, per market, with a prioritised plan your developers and translators can work from.
Whether visitors with another browser language, and Googlebot, are sent away from the version they asked for.
Whether the same URL shows different languages to different visitors, so Google only sees one.
Whether each version is actually written in the language its hreflang and html lang say.
Titles, descriptions, headings, menus, footers and passages copied from another language version.
Pages that have no connected version in some of your languages.
Versions updated at least six months before another version of the same page.
Whether each version links to the same page in other languages, not just to a homepage.
hreflang that points to broken or redirecting URLs, x-default, html lang and og:locale.
The check reads up to 100 pages and tests the homepage and two versions for redirects. For a full validation of every hreflang link, use the free hreflang checker.
Enter a website, one page or a sitemap. The checker groups pages into versions using hreflang, reads up to 100 pages, and requests your homepage and two versions as Googlebot and as browsers set to different languages. It then detects the real language of every version, compares versions with each other and ranks the findings by impact.
The hreflang checker validates the annotations themselves: language codes, return links, canonicals and redirects. This checker looks at what the annotations connect: whether every version can be reached, is really translated and exists in every language. Most international sites benefit from both.
Google crawls mostly from the United States, usually without a language preference. If your site decides the language for the visitor, Google may only ever see one version, and visitors who want another version can't get to it. Google recommends letting visitors choose, for example with a banner that suggests their language.
From the text itself: the writing system and the most common words of each language. It works reliably on a few dozen words and treats closely related languages, such as Danish and Norwegian, as compatible. Titles, menus and passages are flagged only when they are identical to another version and read as that other language.
Yes. Versions such as en-GB and en-US, or nl-NL and nl-BE, are grouped and compared like any other version, and the redirect test shows whether visitors can reach each one. Whether the content is localised enough for each country is something a review judges better than a tool.
