Use Tab, Shift+Tab, Enter, Space, and arrow keys where appropriate to move through the site. Focus should be visible, the order should make sense, and pop-ups should not trap users without a way out. Check menus, forms, carousels, accordions, and consent controls. Accessibility guidance and legal duties vary, so consult authoritative accessibility standards for a full evaluation.
Clear navigation supports a good visitor experience, which Google discusses in its AdSense readiness guidance. A keyboard check is one practical usability test, not a complete accessibility audit and not an AdSense guarantee.
Run SiteReadyScore to prioritize pages, then test controls yourself with a keyboard. Record any element that cannot receive focus or whose function is unclear and repair the component or theme.
