Yes you can. Google AdSense matches advertisements to your site's content and audience, and depending on the type of ad, you can earn money from clicks or impressions.
 

You can place AdSense on your page by using the Google AdSense Widget:
 

  1. Go to Widgets > Ecommerce and drop the GoogleAdSense Widget onto your page. 
  2. A dialog box will open, click on the link in the dialog box to sign up for an AdSense account (if you don't already have one).
  3. Once you've registered your account and customized your ad, copy the advertising code provided by Google.
  4. Paste the code back in the dialog box on your Sitebuilder site and click "OK." Don't forget to republish your site by clicking on the "Publish" button.
