What it means
A one-page footer can also repeat a useful call to action after the main story is complete. It should feel like a deliberate conclusion rather than a storage area for everything that did not fit above. Repeated links can be helpful when they save a long trip back to the header.
Use it in practice
Group related links and make important practical details easy to find. Keep the final action aligned with the purpose of the page.
Watch out for
Do not bury essential contact or legal information in tiny, low-contrast text. Avoid presenting every link at the same visual priority.
