HTML lang attribute missing

What this means

The <html> element has no lang attribute. Search engines use it to determine the page language and serve the page to the right audience in the right region. Screen readers use it to apply correct pronunciation rules. Without it, your pages may appear in unintended language search results and fail accessibility audits.

How to fix it

Add lang to the opening <html> tag on every page.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Page title</title>
  </head>
  <body>
    <!-- content -->
  </body>
</html>

Use the appropriate BCP 47 language tag for the content on each specific page.

Language	Tag
English	`en`
British English	`en-GB`
French	`fr`
Spanish	`es`
German	`de`
Portuguese (Brazil)	`pt-BR`

For multi-language sites, the lang attribute on each page should reflect that page’s language, not the site’s default.

Verify the fix

curl https://yourdomain.com/ | grep '<html'

Confirm the output includes lang=. Then re-run orino audit.
