How to use the Image ALT Checker results

Alternative text should explain the useful purpose of an image when that information is not already conveyed by nearby content. Good ALT text improves accessibility and can also give search engines clearer context about meaningful images. Decorative graphics generally do not need keyword-filled descriptions. Review each flagged image in context and write concise, specific text only when the image contributes information a visitor needs.
