Don't neglect information hierarchy
A disorganized footer can overwhelm users, leading them to either painstakingly examine every link or, more likely, to largely ignore the footer.[1]
To make the footer effective and user-friendly, it's essential to establish a clear information hierarchy. This can be achieved by grouping similar items together and using design elements such as headings, different font sizes, or even varying colors to enhance this structure.
