Good alt text describes the image clearly for people who cannot see it. Focus on the main subject, important action, visible text, and context that helps someone understand why the image is there.
Main subject
Name the person, product, chart, logo, or scene shown in the image before adding secondary details.
Visible action or text
Include what is happening or any important words shown directly on the image, such as a headline, label, or button.
