Are you using any SEO plugin that add SM SEO to posts and pages?
If you are then your best option is to create filters if the plugin provides them for altering this information if the plugins provides the hooks for it.
If you are not then you’ll need to output this information yourself. I would look at one of the popular SEO plugins and see what they are outputting on the page for SM and use that as a guide and a place to start looking into what needs to be done.
