Here how to embed a Google form on your site without using the ugly “Google embed” code. This works great for both polls or signup boxes right in a blog post. Yay, let’s beautify the Internet! Here’s how:

1. Create your Google Form
From your Google Drive account, click Create >> Form. Add all the fields and items that you need in your form.

2. Click “View live form”

Clicking that button will take you to a page that previews what your form looks like. The url will look something like this: https://docs.google.com/forms/d/234234k3lj4k3j4kl23j43kl/viewform

3. Right-click anywhere and select “View Page Source”

4. In the code, find the “form action” URL, which end on “formResponse.”

it will look (start and end) like this:

URL google formResponse

5. Copy that URL and paste in the code of your Web page
