Links are used for navigating to a new page or going to an external page or document.

You should use buttons where the action causes a change to a page, for example submitting a form or opening a pop-up or panel on a page.

Use links in body text, but not in titles, summaries or subheadings. Use a full stop after a link if the link ends a sentence. For links that lead a user to a screen where they can start an action, start your link with a verb.

For links that lead to an information page, put the link in context. You can do this by using the title of the destination page. If the page title does not give context, describe where the link goes.

Tell the user if you’re linking to an external website. For example, "Pension Wise has more information on the lifetime allowance”. Generally avoid using generic links like "Click here”. Generic links don’t make sense out of context and don’t tell a user where the link will take them. Remember, one word links can be hard for users with reduced mobility to use.

Links should be followed by a full stop if they appear at the end of a full sentence, but the full stop should be outside of the link.

If the link appears in isolation, no full stop is necessary.

This is an accessibility requirement, meeting Success Criterion 2.4.4 Link Purpose (In Context), level A.
