A Google Form is a website, and to embed it into a LibGuide box, or to put it on another website, like a Wordpress installation, use iframes html code (Send via < > )
Copy the iframe code and paste it into your web page editor. Make sure you're using the plain text option, and not the rich text option!
If you're embedding an iframe in LibGuides, you'll have to change the width to be slightly narrower than column width, so the form doesn't overhang.
