What Is Alt Text and Why It Matters?

Alt text (alternative text) is a short description added to an image's alt attribute in HTML. It serves two primary purposes: it provides a textual alternative for screen readers and displays when an image fails to load, and it gives search engines context about the image. Well-written alt text improves accessibility, enhances user experience, and can contribute to image SEO.

Best Practices for Alt Text
