The “Inappropriate Page Language Check” evaluates whether the primary language of the webpage is correctly identified using the lang attribute on the <html> element.
Example outcome
I verified that the webpage main language is incorrectly marked. Does \"en-GB\" exists?
Impact
Visual Impairments: Users may hear text read in an incorrect accent or with incorrect pronunciation, especially for non-English sites or non-default dialects.
Cognitive Disabilities: Language-specific tools (like simplified vocabulary versions or screen overlays) may not trigger correctly, reducing comprehension.
Auditory Disorders: Mispronunciation can make understanding spoken content more cognitively demanding.
Fixes
To address inappropriate page language:
Determine the language in which the page’s content is mainly presented.
Verify which is the correct language code for that language.
Change the language code in the lang attribute of the <html> tag.
