Do your languages know about each other?

Hreflang links tell search engines that a page’s languages are versions of one page, so they can show a searcher in Denmark the Danish one. A link that only goes one way is ignored. Paste each language version and see which links hold. Nothing you paste is stored.

Page 1
Page 2

Paste one language version of the page in each box. To get a page’s HTML, open it, right-click and choose View page source, then select all and copy.

Also free: the translation drift checker, for a translated page that no longer matches the original, and the search and sharing checker, for what a page shows in search results and when shared. All free tools
