Needs attention (7)

Sitemap
Fail60technical
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.
- mediumtechnical · 90% confidence
  Sitemap is missing localized URLs
  A sitemap was found, but sampled entries do not include locale-prefixed URLs.
  Found here
  Sitemap · sitemap.xml
  https://www.twitch.tv/sitemapv2_index.xml.gz
  What we saw
  Sitemap https://www.twitch.tv/sitemapv2_index.xml.gz has no locale-prefixed URLs in the sample
  How to fix it
  Include localized URLs in the sitemap for every published locale.
Structured data
Fail0technical
JSON-LD inLanguage should match the page locale when structured data is present.
- lowtechnical · 95% confidence
  Structured data omits inLanguage
  JSON-LD is present but does not declare inLanguage on sampled pages.
  Found here
  JSON-LD · <script type="application/ld+json">
  https://www.twitch.tv/
  What we saw
  Organization is present but inLanguage is missing
  How to fix it
  Set JSON-LD inLanguage to match each page locale.
Translation completeness
Fail0linguistic
Localized pages should not leave source-language copy in place, except brand names and URLs.
- highlinguistic · 92% confidence

  Found here

- highlinguistic · 95% confidence
  Page script does not match the locale
  A el-gr page is dominated by Latin-script copy.
  Found here

- mediumlinguistic · 95% confidence
  Terminology inconsistency
  "Just Chatting" appears both untranslated and translated across de pages. Affects 6 sampled pages.
  Found here
  Header · <nav> or <button>

  How to fix it
  Use one translated label for "Just Chatting" across de pages.
Text expansion
Fail40visual
Longer translations should not create obvious length pressure versus the source UI.
- mediumvisual · 88% confidence
  Localized text is much longer than the source
  A bg string is 330% the length of the source, which often causes overflow. Affects 39 sampled pages.
  Found here

  How to fix it
  Shorten the translation or give the control more room so the longer copy does not overflow.
Font and script support
