  Comment le corriger
  Verify that switching locale from a deep page retains the same path and relevant query or booking state.
Sitemap
Échec18technique
Like Lighthouse: a valid XML sitemap must be discoverable, robots.txt should reference it with an absolute Sitemap: URL, and localized URLs should appear for published locales.
- hightechnical · 100 % de confiance
  Valid sitemap not found
  No fetchable XML sitemap with URL entries was found at /sitemap.xml or via robots.txt.

Échec65technique
lang, aria-label, and alt text should match the page locale.

  Comment le corriger
  Translate leftover source-language CTAs to match the surrounding locale copy.
- infolinguistic · 25 % de confiance
  No localized page copy is available for comparison

Target copy should preserve the source meaning, numbers, and product actions.
- infolinguistic · 25 % de confiance

Échec50visuel
Language-specific images and alt text should match the page locale.
