Page language missing or invalid

Warning severity, in the accessibility tab

Why it matters

The <html> element has no valid lang attribute, so screen readers may read the page with the wrong pronunciation rules and search engines lose a language signal.

How to fix it

Add lang="en" (or the right BCP 47 code) to the <html> element.

How Crawlune finds it

Crawlune flags Page language missing or invalid automatically on every crawl and lists the affected URLs under the accessibility tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 550 URLs with every check enabled.
