Paste a page and we'll check its hreflang alternates for missing return links, duplicate codes and a missing x-default.
Check your hreflang tags for missing return links, invalid language and region codes and a missing x-default, so each country and language sees the right version of your site.
01
Language and region codes
Valid ISO codes such as en-gb, en-us and de-de.
02
Return links
Every page linking back to every alternate, as hreflang requires.
03
x-default
A fallback for visitors whose language you don't target.
04
Self-references
Each page including itself in its hreflang set.
- 1
Enter a page URL
One of your localised pages.
- 2
Check the set
We read its hreflang tags and check each alternate page links back.
- 3
Fix the gaps
Add missing return links, correct codes and set an x-default.
Complete set
Valid codes, self-references, return links on every alternate and an x-default.
No x-default
Not required, but recommended so unmatched visitors get a sensible default.
Missing return links
Without reciprocal links, search engines may ignore your hreflang entirely.
Hreflang tells search engines which version of a page to show for each language and region. Errors can show UK prices to American shoppers, or the English page to German searchers, hurting conversions and rankings in every market.
About the hreflang checker.
An HTML attribute that tells search engines about language and regional versions of a page, so they show the right one to each user.
