SHOULD LINKS BE UNDERLINED? IT'S WORTH A/B TESTING

Summary from the TLDR Marketing newsletter

Underlining links improves usability and accessibility, even if it affects visual appeal. Google's tests showed that removing underlines reduced clicks, slowed interaction, and lowered revenue. Hover underlines had little impact and were shipped for competitive reasons. Details matter because hover states and larger targets can help recognition, while color-only links hurt performance. Accessibility standards warn against relying on color alone, since many users are colorblind and hover cues fail on touch devices.
