Hreflang checker
Check a page's hreflang tags and visit every alternate it names: does it answer, can it be indexed, does its canonical name itself, and does it link back?
Free and unlimited: does not use your weekly runsWhat the checker tests
First the set on your page, from the HTML and the HTTP Link header: valid language and region codes (such as en, en-GB or x-default), one URL per code, a reference to the page itself, an x-default, and whether the page itself is indexable and canonical, because search engines ignore hreflang on a page that is not.
Then it fetches up to 20 alternates. For each one you see its status (200, a redirect or an error), whether search engines may index it (robots.txt, meta robots and X-Robots-Tag), whether its canonical points to itself, and whether it has a return tag: a hreflang link back to your page. Without that link search engines ignore the pair.
The most common hreflang mistakes
Missing return tags, alternates that redirect or are canonicalized to another URL, country codes used as language codes ("uk" for the United Kingdom instead of "en-GB"), and a page that does not list itself. Each of these makes search engines drop part of the set.
