Ad Types

Google Ad Manager provides a variety of different ad types – out-of-page, HTML 5, expandable, etc. Those are typically set up within DFP.

Then, in Metro Publisher you can insert those by using an HTML Sprocket to add the custom code to any section where you'd like the ad to appear.

Or, if you want it to appear globally, you could insert the code into the header for your site. You can do that by logging in as an Admin and going to Settings > HTML Embed.
