Definition:
A hamburger menu is a website navigation icon made up of three stacked horizontal lines (☰) that, when tapped or clicked, reveals the site’s menu options.
Why it matters:
Hamburger menus are common on mobile websites because they save screen space. But they can also hide important links, make navigation less obvious, and hurt conversions if overstuffed.
Example:
Instead of crowding your mobile header with links, many sites use a hamburger menu to tuck navigation away. But for conversion-critical links—like your primary CTA—it’s often smarter to keep them visible.
