How to diagnose reciprocal hreflang failures.
A missing return link is not a property of one page. It is a failed relationship between a declaration and the target's delivered language graph.
Complete evidence✦Explicit boundaries✦Verifiable outcomes
Inspect both pages
Keep the declaring URL, target URL, expected language, and target's actual declarations in one evidence row. Then classify whether the target has no hreflang, omits the declaring language, or points to another URL.
Resolve response and canonical problems first
- Check direct response status and final URL
- Confirm the target is indexable and appropriately self-canonical
- Separate redirects from missing reciprocity
- Compare sitemap and crawl coverage before calling a cluster complete
Verify the pair
Fetch and parse both pages after the repair. A successful target response alone does not prove that the return declaration is now present.
