In October, Google Sites gained the ability to create page templates. Templates can include settings and layout, as well as content you want on each page that gets created.
Combining templates and the ability to copy sites, gives users powerful abilities, particularly with respect to customer and project portals. Once a portal has been designed, you can copy the site and build it out using templates to ensure consistent layout and content across sites and pages.
The update also includes the ability to subscribe to RSS feeds from ‘announcement’ pages, letting users track posts and conversations via your favorite RSS reader.
