Alt Text Best Practices

What is Alt Text?

Alt text (alternative text) describes an image’s content. It’s used by:

  • Search engines to understand images
  • Screen readers for accessibility
  • Browsers when images fail to load

Writing Good Alt Text

Do:

  • Describe the image accurately
  • Include relevant keywords naturally
  • Keep it under 125 characters
  • Be specific and descriptive

Don’t:

  • Start with “Image of” or “Picture of”
  • Stuff keywords unnaturally
  • Leave it blank
  • Use the same text for all images
