Step 3: Optimize
Optimize Surface Form loading speed
Add the following code to your site's <head>. With
WPCode, go to Code Snippets >
Header & Footer and paste it into the Header section.
<!-- 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.
If the form uses a custom domain, replace forms.withsurface.com in the connection hints with your verified domain. See Use the Surface Tag with a Custom Domain.
