An Alias is an alternate URL for a page on your web site. You can create an Alias for the old address of a page that has been moved so users will be redirected if they attempt to access the old address. You can also use an Alias to create a short URL for a page so you can reference it more easily in a marketing campaign, email, or on Twitter.
When you move a page, you can easily create an Alias for the old address. If you move the page using the Navigation Tree, you will be prompted with a dialog box. Otherwise, if you move a page using the Child Pages tab, you will need to check the box below the Destination Page field.
Additionally, you can create an Alias manually on any page.
Step 1: Go to a page where you want to add an Alias.
Step 2: Select Aliases from the Properties menu.
Step 3: Click the Add button to add a new Alias.
Step 4: Enter the address of the new alias in the Alias field, making sure to leave the leading slash (“/”) in place.
Step 5: Enter a Comment.
Step 6: Press Save when complete.
