What Is Alt Text?

Alt text (alternative text) is a short written description of an image. It helps screen readers describe visuals to visually impaired users — and it's displayed when an image doesn’t load.

3 Key Reasons to Use Alt Text

  • Accessibility: Alt text ensures your content is available to all users, including those using screen readers.
  • SEO: Search engines can’t “see” images — they rely on alt text to understand them.
  • Fallback: If an image breaks, the alt text is shown instead, preserving context.

Tips for Writing Great Alt Text

  • Keep it short and descriptive (under 125 characters)
  • Focus on the essential purpose of the image
  • Avoid phrases like “image of” or “picture of” — just describe it
  • Include keywords naturally, but don’t stuff them
