All 404 pages automatically suggest relevant pages based on the requested URL. If users land on a 404 page, an agent analyzes the path and retrieves semantically related pages from your documentation to help them find what they’re looking for. You can customize the title and description of the 404 error page. Use the description to add helpful links or guidance.
