Rule page.lang.missing
Set <html lang>
page.lang.missing is a check in Crawlmind's site audit that grades low-impact issues of this kind. This page explains why the rule matters and the exact fix.
Why it matters
The `lang` attribute tells crawlers, screen readers, browser translators, and AI assistants what language the page is in: and which voice/dictionary to use. Missing `lang` defaults every consumer to a guess that's wrong about as often as it's right.
The fix
```html
<!-- BCP 47 language tag -->
<html lang="en">
<!-- Region-specific (only when content actually differs by region) -->
<html lang="en-GB">
```
