To support SEO, Ghost should generate a sitemap.xml.

The best format for this is likely to follow the work of Yoast and his SEO plugin for WordPress, which creates separated XML sitemaps for different content formats, brought together in a main XML file and served through an XSL template. This has been widely tested and updated over the years.

Demo: http://marketplace.ghost.org/sitemap.xml

For us the sitemap structure would be:

• Index
  • Posts
  • Pages (contains home)
  • Tags
  • Authors

These should be generated once and saved in the filesystem. When a post is published or updated it should update the posts sitemap, when a page is published or updated it should update the pages sitemap, when a user is created or updated... and so on.
