Link Purpose (Link Only)

The strict version: a link's own text should say where it goes, without needing the surrounding sentence for context.

In plain English

The Level A rule (2.4.4) lets a link lean on its sentence for meaning. This AAA rule says the link text on its own should tell you where it goes. That matters because screen-reader users often jump through a page by pulling up a bare list of every link, with no surrounding words to explain them.

So “Read more” or “Click here” repeated ten times becomes ten identical, meaningless entries. “Read more about our return policy” works on its own.

Who this is for

  • Screen-reader users navigating by an out-of-context list of links.
  • Everyone skimming, who reads link text first and the sentence second.

How to check and fix it yourself

Scan your page for generic link text and rewrite it to describe its destination. If the visible text must stay short, add an aria-label with the full purpose.

<!-- weak: only makes sense in its sentence -->
<a href="/returns">Read more</a>

<!-- strong: clear on its own -->
<a href="/returns">Read our return policy</a>

<!-- short visible text, full purpose for assistive tech -->
<a href="/returns" aria-label="Read our return policy">Read more</a>

Where we can help

We pull the list of every link the way a screen reader does and flag the ones that are meaningless out of context. Vague “click here” links are a recurring item on the common failures list.

Frequently asked questions

What does link purpose (link only) require?+

Success Criterion 2.4.9 (Level AAA) says the purpose of each link should be clear from the link text alone, without relying on the sentence or context around it. The only exception is where the destination would be ambiguous to everyone.

How is this stricter than 2.4.4?+

2.4.4 Link Purpose (In Context) (Level A) lets you use the surrounding sentence, heading, or list item to clarify a link. 2.4.9 (AAA) removes that help: the link text by itself must be enough.

Why does the link text alone matter?+

Screen-reader users often pull up a list of all links on a page to navigate. In that list there is no surrounding sentence, so twenty links that all say 'Read more' or 'Click here' are useless. Self-describing link text fixes that.
