WAIT… Make sure that you have added the Surface Tag to your site before proceeding.

​
iFrame Embed Code

Add the following code wherever you’d like the form to appear: 
<!-- Start Surface Form Embed -->

<iframe
  src="REPLACE ME WITH FORM URL"
  allowfullscreen
  loading="eager"
  fetchpriority="high"
 >
</iframe>

<!-- End of Surface Form Embed -->
Replace REPLACE ME WITH FORM URL with your actual Surface form URL. You can find this URL by clicking the “Share” button in the Overview section of the form.

​
Optimize Speed

Add the following <link> tags inside the <head> of your site: 
<!-- Speed up connections to forms.withsurface.com by performing early DNS resolution and TCP handshake -->
<link rel="dns-prefetch" href="https://forms.withsurface.com">
<link rel="preconnect" href="https://forms.withsurface.com" crossorigin>

<!--  Fetch the form in advance, so it's ready when a user opens it. -->
<link rel="prefetch" href="REPLACE ME WITH FORM URL" as="document">
Replace REPLACE ME WITH FORM URL with a Surface Form URL.

​
Explanation

  1. dns-prefetch → Resolves the domain early to skip DNS lookup delays.
  2. preconnect → Prepares the TCP + TLS handshake so the browser is ready to request assets immediately.
  3. prefetch → Fetches the form in advance, so it’s ready when a user opens it.
