When a page slug changes, a custom URL in a menu may continue pointing to the old path. Edit the relevant menu or navigation block, select the current page destination, and save. If the old URL has external links, add a relevant redirect and update internal links. Avoid redirect chains or sending unrelated pages to the homepage.
Test the menu from the homepage and an article on desktop and mobile. Confirm the destination loads without an extra redirect and displays the intended content. Google’s approval guidance identifies broken links and difficult navigation as possible concerns.
Use SiteReadyScore to check public navigation signals and URLs. Then manually verify the exact menu path and update the WordPress navigation for every relevant template.
