  • Provide link text that describes where the link goes and gives meaning out of context.
    • Avoid phrases like “click here,” “learn more” and “read more”.
  • Underline links for quick identification.
    • Do not underline non-link text.

  • Provide alternative (alt) text to images that convey meaning.
  • Keep the alt text short and concise (about 125 characters).
  • Hide images from screen readers that do have meaning or are for decoration.
    • Use an empty alt value (alt="")
  • Use the alt Decision Tree
  • Avoid images with text when possible. If necessary, add alt text.

Create an accessibility statement for your website. Users of your content will usually refer to accessibility statements when they encounter problems. Provide information that is useful to the users and is easy to find. Use the W3C Web Accessibility Initiative (WAI) tool to create an Accessibility Statement.
