Short answer
A hreflang reciprocity check compares the alternate set on every supplied localized page. Each page should use valid language or language-region tags, include itself, point to the same alternate cluster, return links from other supplied pages, and normally keep a self-referencing canonical.
- Best fit: multilingual launches, regional migrations, and international SEO QA
- Outperformance angle: page-set reciprocity and canonical conflict checks without crawling or uploading site data

More Variations
Hreflang return-tag QA across real page sets
A tag generator can create one alternate block, but it cannot prove that every localized page links back. This checker compares the supplied page sets and names the exact source and target where reciprocity breaks.
Locale, self-reference, and x-default checks
The audit validates BCP 47 locale syntax, catches duplicate locale rows, confirms each page includes itself, and recommends x-default when a fallback row is missing.
Canonical conflicts stay separate from on-page checks
This tool focuses on the relationship between localized equivalents. It flags a supplied canonical that points away from the source page without duplicating broad title, heading, content, or metadata checks.

Why this tool page should rank
Searcher job
Verify that supplied localized page sets use valid locales, self-links, return links, x-default guidance, and compatible canonicals.
Competitor gap
Tag generators cannot prove return links across pages; this checker should name the exact supplied source and target where the cluster breaks.
Use it now
Paste one block per localized page, fix self-reference and locale issues, then resolve missing reciprocal links and canonical conflicts.

Frequently Asked Questions
What input format does the checker support?▾
Use one block per page. Add SOURCE: URL, optional CANONICAL: URL, then one locale: URL row per alternate. Separate page blocks with a blank line.
What is a reciprocal hreflang link?▾
If page A lists page B as an alternate, page B should list page A in its own alternate set. This confirms that both pages belong to the same localized cluster.
Does every hreflang set need a self-reference?▾
Yes. Each localized page should normally include its own URL in the alternate set alongside every equivalent language or regional version.
Is x-default required?▾
It is not mandatory for every implementation, but it is recommended when you have a global fallback, language selector, or page for unmatched users. The checker reports it as a recommendation.
What canonical conflicts does the tool detect?▾
When a canonical is supplied, the checker flags a page whose canonical points away from its own source URL. Localized alternates usually need self-referencing canonicals rather than canonicalizing all languages to one page.
Does the tool report missing links to pages I did not paste?▾
No. Reciprocity is verified only when the alternate target also appears as a supplied SOURCE block, avoiding false failures for pages outside the pasted set.
