WCAG 2.0 AA Compliance

Section 2.4.4

The purpose of each link can be determined from the link text alone or from the link text together with its programmatically determined link context, except where the purpose of the link would be ambiguous to users in general.

This section provides another simple premise: to make all links understandable so that an impaired user may navigate through the page properly. If you name your links properly (like using Technique G91: Providing a link text that describes the purpose of a link) then not only do you satisfy this section on the AA level, you will also satisfy it on the AAA level. Note that the previous link was an example in and of itself.

Under this section, you're also allowed to use out of context links in order to maintain the natural language of your web page, but you must make sure that the link is within the same proper semantic markup that we've discussed previously. The following is an example of how to not place an out-of-context link:

<p>There are certain ways that you can fail Section 2.4.4, one example being F63.</p>
<p><a href="">Read more...</a></p>

You should always ensure that related links and the content that it is related to is grouped together properly so that links don't lose its meaning. One last thing you should always ensure is that images serving a purpose as a link have an alt attribute or there is text provided immediately before/after the image, as demonstrated below:

<a href="nextpage.html"><img src="nextbutton.jpg" alt="Go to next page" /></a>

<a href="nextpage.html"><img src="nextbutton.jpg" alt="" />Next page</a>
