Validates codes like en-US, zh-Hant, x-default
Language and region matrix for each page group
Plain problem list with fixes, CSV download

Hreflang Checker helps sites that offer more than one language or region. Type your site address and the app reads your sitemap, including its language entries, and the hreflang tags in each page. It checks that every page lists itself, that each language version links back to the others, and that the codes are valid, such as en, fr-CA, zh-Hant or x-default. It flags duplicates, underscores like en_US, mixed capital letters, and a page language that disagrees with the code the page declares for itself. It also checks that every listed page loads and is not redirected, blocked in robots.txt, set to noindex or pointing to a different canonical address, and that the sitemap and the page tags agree. Results appear as a language and region matrix for each group of pages, plus a plain list of problems that says what each one means and where to look in your site's language and SEO settings. Download the list as a CSV file. The app only reads your own public pages and sitemap files, cannot know which languages you intend to offer, changes nothing on your site, and makes no promise about how search engines treat the result. No watermark, no sign-up, no visitor data collected.
