Hreflang tags tell Google which version of your page to show to users in different countries and languages. Get them wrong and Google may show the wrong language version to the wrong users — or ignore your international pages entirely.
🌍 Check Hreflang Tags All Audit Tools →You need hreflang tags if your site has pages in more than one language, or if you have separate versions of pages targeting users in different countries — for example a .com targeting the US and a .co.uk targeting the UK. Without hreflang, Google may choose the wrong page to serve to international users, or may treat your translated pages as duplicate content.
Every page referenced in a hreflang set must include hreflang tags pointing back to all other pages in the set. If your English page references your French page but your French page does not reference your English page, Google ignores the entire set.
Hreflang uses ISO 639-1 language codes (en, fr, de) and ISO 3166-1 region codes (GB, US, FR). Common mistakes include using EN instead of en, UK instead of GB, or using full language names instead of codes.
Every hreflang implementation needs an x-default value specifying the fallback page for users whose language and region are not explicitly targeted.
