Find broken hreflang links across language versions
What you put in
You paste page URLs or upload an XML sitemap, a CSV export or an HTML file. One run checks up to 5,000 URLs. Only the alternates your pages declare are checked. Pages outside the set you submit stay unseen, so include every language version. You get 3 free jobs a day with a free account, and failed jobs do not count.
Reading the findings
You get result.json, findings.csv, http-evidence.csv and read-me.txt. Findings are grouped per set of language versions and split into syntax errors, missing return links and canonical conflicts. A missing return link means page A names page B, but B does not name A back. Codes such as en-UK or de_DE are flagged. Each finding comes with a suggested fix you can check in the page source.
Live checks and your judgement
With Check live responses on, each declared alternate is requested once. Its status code and canonical go into http-evidence.csv. Crawling is bounded, so pages outside your submitted set are not fetched. A code can be valid and still be the wrong choice for your market, which is your decision. The report makes no ranking prediction. It points to markup problems, and traffic effects depend on things this tool never sees.
Questions before you run it
What counts as a missing return link?
Page A names page B as an alternate, but B does not name A back. Those one-way pairs are listed per cluster, because search engines disregard hreflang annotations that are not reciprocal.
Does it check that my language and region codes are valid?
Codes are syntax-checked against the expected language and optional region pattern, so entries like en-UK or de_DE are flagged. A code can be well formed and still be the wrong choice for your market, which stays a judgement call.
Can I feed it a sitemap instead of a URL list?
Yes. The Source control accepts page URLs, an XML sitemap or a CSV export, up to 5,000 URLs per run.
What does the Check live responses option actually fetch?
With it enabled, each declared alternate is requested once and the status code and canonical are recorded in http-evidence.csv. Crawling is bounded, so pages outside your submitted set stay invisible to the run.
Will fixing the findings improve my rankings?
No prediction is made. The report separates syntax errors, missing returns and canonical conflicts so you can fix concrete markup problems; traffic effects depend on factors this tool never sees.
