How TheSiteFuse checks "Language declared"
The lang attribute on the main HTML tag (<html lang="en">) indicates the content language. Browsers and screen readers use it to choose the right pronunciation and adapt the interface.
Why it matters
Real-world impact of "Language declared"
It's a WCAG accessibility criterion. Without lang, screen readers may pronounce text in the wrong language, making the site incomprehensible for the visually impaired. Google also uses it for geographic targeting.
