What is the HTML lang attribute?
The HTML lang attribute (e.g., <html lang="en">) declares the primary language of a webpage. It helps search engines serve the right content and enables screen readers to use the correct pronunciation.
What happens if the lang attribute is missing?
Without a lang attribute, search engines may misidentify your page's language, leading to poor rankings in the wrong region. Screen readers may also mispronounce content, harming accessibility.
