For pages that don't have appconfig parameters created/specified allowing you to change these from within the admin section will need to be specified manually. Because each of the pages inherit from the SkinBase class, you can access and set these properties directly in the Page_Load method. For example, to set the meta description in the shoppingcart.aspx page, open the shoppingcart.aspx.cs page and add
Code:
SEDescription="your description";
to protected void Page_Load. Alternatively, you could set the SEDescription to a string resource you've created, or a new appconfig you've created so that you would then have control of these via the admin section
