10 min Impact: medium Effort: low ✓ Scan-verified — no manual checkbox

How to fix it

1

Add the lang attribute

<html lang="en"> (or the appropriate language/region code) at the top of every page.
2

Match it to your actual content language

If you serve multiple languages on different pages, each should declare its own correct lang value.
