Validate hreflang XML sitemap
Ready. No data uploaded.
Output
Interpretation and limitations
hreflang annotations describe language/region alternatives; they do not force Google to choose a particular URL. Each language version should normally link to itself and its alternatives. Reciprocity is verified only among the supplied page HTML or sitemap entries; no remote website is fetched. Validate production page URLs and canonical relationships separately.
