Best Practices for accessible Links

It is essential that users can find, identify, and comprehend hypertext links quickly. Even though there are no Level 1 (A) checkpoints associated with links it is pretty easy to fulfill Level 2 and even Level 3. It's definitely worthwhile the little effort with the added benefit that e.g. most browsers render the title attribute as a tooltip.

Basic Rules

See also my Design Guidelines for Links.

  • Contrast link text color and regular text color
  • Underline link text
  • Ensure link text is descriptive of its destination
  • Make visited links change color
  • Limit link text to a maximum of four words
  • Place important words at the front of link text
  • Minimize amount of links to seven (excluding the menu) unless they are presented in a clear structure
  • Use meaningful pathnames when creating directory structure

Best Practices

Level 1

No Level 1 requirements.

Level 2

Level 2 Checkpoints - Section 508 Compliancy Standards
Checkpoint Description W3C 508 Example
Links Clearly identify the target of each link 13.1 n/a <A href="my-doc.html">My document is available in HTML</A>,<A href="my-doc.pdf" title="My document in PDF">PDF</A>,

<A href="my-doc.txt" title="My document in text">plain text</A>

Level 3

Level 3 Checkpoints - Section 508 Compliancy Standards
Checkpoint Description W3C 508 Example
Links Create a logical tab order 9.4 n/a <A tabindex="2" href="link2.txt"">Link 2</A><A tabindex="1" href="link1.txt">Link 1</A>

<A tabindex="3" href="link3.txt">Link 3</A>

Links Provide keyboard shortcuts to important links 9.5 n/a <A accesskey="2" href="link2.txt"">Link 2</A><A accesskey="1" href="link1.txt">Link 1</A>

<A accesskey="3" href="link3.txt">Link 3</A>

Links Include non-link, printable characters (surrounded by spaces) between adjacent links 10.5 n/a [<A href="a.htm">Link A</A>] [<A href="b.html">Link B</A>] or<A href="a.htm">Link A</A> | <A href="b.html">Link B</A>
