Not sure what your question is
if you are asking to create a footer that should appear in all the pages then create the footer in your master page and create all your body pages on top of this master page. You can still have dynamic information in footer i.e. page no. etc.
If you are asking to create different footers for different pages then
if you want a specific footer per page then design the footer in the page itself instead of making a generic footer in master page
if you want to reuse some of the footers then create multiple master pages and use them accordingly
