Many websites no longer use the old blue, underlined link style. That is fine, provided visitors can still recognize links. In my original article I argued for one consistent link style throughout a site. It remains a simple way to avoid uncertainty.
Show what is clickable
Choose a clear visual distinction between ordinary text and a link, then use it consistently. A subtle color alone may be difficult for people with limited color perception. Underlining is often useful, especially within a paragraph. A change visible only when a mouse hovers does not help someone on a phone or using a keyboard beforehand.
Inspect a page without already knowing which words are linked. Can you find them quickly? Is focus visible when you navigate by keyboard? Design conventions should keep the route to information clear.
Say where the link goes
Where possible, replace 'click here' with words describing the destination. The W3C guidance on link purpose explains that meaning should be apparent from the link text or immediate context. Google also recommends descriptive anchor text. The aim is not to pack in keywords, but to let a reader know what to expect before clicking.
