Questions
Hreflang Checker FAQ
What does the Hreflang Checker analyze?
It checks language and region codes, duplicate and conflicting values, x-default, absolute HTTPS URLs, canonical alignment, self-reference, and reciprocity limitations.
Does every website need hreflang?
No. Hreflang is useful for equivalent pages intended for different languages or regions.
Can this checker confirm reciprocal links?
No. This version analyzes one pasted page. Every alternate page must be checked for the same complete cluster.
Does SiteTend store pasted HTML?
No. Analysis runs in your browser, and pasted HTML is excluded from analytics.

From finding to verified fix
Interpret the finding
Each language-region alternate should be valid, reciprocal, and aligned with a canonical page in the same language set.
Common causes to inspect
- Missing return links
- Invalid language or region codes
- Alternates pointing through redirects or to noncanonical pages
Practical next steps
- Map the complete alternate set
- Correct codes and absolute URLs
- Verify reciprocity on every deployed alternate
What this check cannot prove
Pasted markup cannot fetch alternate pages, validate their content language, or confirm search-engine processing.
