Kit Landing Page Testimonials via Script

Kit, the email platform once called ConvertKit, hosts landing pages for lead magnets and launches. Its classic landing page editor has a Script block: a Source field for code and a Container Height field in pixels. Leave that height at zero and the script still runs, but nothing is visible. Get the height right and a StoryProof widget sits right under your signup form.

Kit Script block

Code for a Kit landing page

Enter a widget id. Block 1 goes into the Source field of a Script block on a classic Kit landing page. Block 2 is the plain button for a page built in Landing Page 2.0, whose help article lists no code block.

Shown in StoryProof when you copy a widget’s embed code.

Button block on a Landing Page 2.0 page

Button text:  See what subscribers say
Link:         [your StoryProof Wall of Love link]
Place it:     directly under the subscribe form

In the Edit Script window, set Container Height to a number of pixels before you save. Start around 600, click Preview at the top right of the builder, then raise or lower it until the whole widget shows without a big gap.

Built in your browser from the id you enter. Kit and StoryProof receive nothing from this box.

The problem, solved

Kit landing page snags, and the StoryProof fix

  • Problem 1

    I pasted the code and nothing appears

    Kit says a Script block left at its default Container Height of zero does not appear on the page, even though the script still runs.

  • Problem 2

    The widget gets cut off at the bottom

    A fixed pixel height that fits a three card row will be too short for a tall wall.

  • Problem 3

    My page was built in Landing Page 2.0

    Kit’s Landing Page 2.0 help lists headings, paragraphs, buttons, images and links, and mentions no HTML or script block.

  • Problem 4

    Subscribers love the freebie but never say so

    Without an ask, the only praise you get is a stray reply to a welcome email.

In StoryProof

Add the widget to a classic Kit landing page

Step 1 of 5

Open the landing page

In Kit, open Landing Pages & Forms under the Audience growth tab in the left navigation, and click the landing page.

Before you start

Limits on Kit

  • Fixed container height

    Kit sizes the Script block by the pixel height you enter. A widget that grows past it will not show in full, so recheck after changing the layout.

  • No code block documented for 2.0

    Kit’s Landing Page 2.0 article lists no HTML or script block. On those pages the honest route is a button to the Wall of Love.

  • Plan rules are unclear

    Kit’s script article states no plan requirement. A Kit product update seen only in search results says custom HTML on landing pages is for paid plans, so check your account.

  • Embedded Kit forms are separate

    This page covers Kit’s hosted landing pages. A Kit form embedded on your own website is installed on that website instead.

  • Kit help as of 2026-11-14

    Menu names and the container height rule come from Kit’s help articles as read on 2026-11-14. The steps have not yet been followed on a live Kit account.

FAQ

Questions people ask

Short answers to what usually comes up next.

Should the widget go in a Script block or an HTML block?

Kit’s help on embedding scripts in landing pages describes the Script block with its Source field. That is where both StoryProof lines go on a classic page.

Why can I not see the widget while I edit?

Kit says scripts have no visible effect in the landing page builder. Use the Preview button to see the live version.

Can I put testimonials in my Kit emails instead?

Emails are a different medium where scripts do not run, so a widget is the wrong tool there. Our email campaign guide covers quoting testimonials inside messages.

Does the widget collect email addresses?

No. Kit’s form keeps doing that. The StoryProof widget only shows the testimonials you approved and chose for it.

Still have a question? Ask the StoryProof team or book a demo.
