Web Press pages can be either connected or referenced, while external pages can only be linked using a direct URL.
In Web Press, where a web page (basic page) is connected determines where and how the web page will publish, as well as how the breadcrumb is formed.
In order to prevent publishing issues, Web pages should only be connected once.
Only connect once
In order to prevent publishing issues, basic pages should only be connected once.
Unless you are creating a new page, or moving an existing one, you should reference the web page.
In Web Press, referencing a web page (basic page) will prevent your site from displaying a broken link. If the referenced web page has its filename or publish location changed.
Any web page that is managed in our Web Press system can be referenced to.
Assign (direct URL)
Any web page that isn't managed in our Web Press system is referred to as an external URL. This means that external URLs cannot be connected or referenced by Web Press, and must simply be added using the web page's direct URL.
