Inserting gadgets
To easily embed rich media, retrieve feeds, or perform simple tasks like managing a to-do list, you can insert gadgets into your Google site. Click Edit page, select Insert, and choose one of the gadgets in the menu.
For example, insert the Recent posts gadget to display the announcements posted to the site, or the Recently updated files gadget, to show recent files. To view gadgets created by third-party sites, click More gadgets... and a window appears.
Select the type of gadget you want to insert by clicking the links on the left side, select a gadget, and click OK to save. If you'd like to first check how the gadget looks in your Google site, click Preview Gadget first.
