Embed URL (iframe)
We can now embed sites in iframes by using the Embed URL option. If the site allows embedding and its URL begins with https you will have the option to embed the whole page, or you can select to show only the site information and a link.
Google doesn't allow iframing of sites that aren't on HTTPS to prevent browser mixed-content errors.
