How hreflang tag generation works

For each language the tool builds the matching URL from your chosen structure (subdir / subdomain / query), emits rel="alternate" hreflang tags plus x-default, ready to paste into each page head. Purely local.

  • Every language page must carry the full set of hreflang tags (including itself) referencing each other, or Google may ignore the group.
  • Make sure each generated href points to a page that really exists; dead links invalidate the annotation.

FAQ

1. Does every page need hreflang tags for all languages?

Yes. Each language version must list all languages (including itself) and reference each other, or Google may ignore the annotations; x-default points to the language selector or default page.

2. How do I choose subdir, subdomain or query strategy?

It depends on your site actual multilingual URL structure. The tool generates links for all three; pick the one matching your routing so every href points to a page that really exists.

3. My hreflang tags are in place but not working, or Search Console reports hreflang errors — why?

Four causes account for most of it: (1) missing return links — if page A points to B, then B must point back to A, or the whole cluster is ignored; (2) malformed language-region codes, such as the non-existent en-UK when the correct code is en-GB; (3) hreflang pointing at a URL that redirects or 404s, when it must point at the address that finally returns 200; (4) no x-default, leaving users whose language matches nothing without a fallback. The tags this tool generates include reciprocal links and x-default by default.
