Choose Insert, and then More Gadgets.
In the Google Sites Editor, open the Insert menu. You will see a list of components you can embed on your site, like Tables, Images, and Links. Select More Gadgets. This allows you to install customizable tools such as the POWr Star Rating to your site.
Paste in URL
You will see the Gadget manager. Select Add Gadget by URL. Then paste this URL into the field. Choose Add to complete.
Change Height and Width
Now that you have embedded your new, fully customizable Star Rating Widget onto your website, you'll probably want to change the shape and size of the Widget. Using the options in the pop-up, pick a height and width for your plugin. We don't recommend it, but you can insert a scrollbar, title or border to your Star Rating Widget. You will have more editing options through the plugin.
Set up POWr Star Rating
Go to the live Google Sites web page and select the settings gear in the top right corner of your Star Rating Widget.
In the POWr Editor, click Import Existing Star Rating, find Star Rating- and click Copy.
