Boost Conversions: How to Auto-Populate MCAE (Pardot) Form Fields

When it comes to improving form conversions and user experience in Marketing Cloud Account Engagement (MCAE), pre-populating form fields is one of the most effective strategies.

It reduces the effort for your prospects, helps ensure accurate data, and delivers a seamless experience, especially when prospects revisit your website or click through an email link.

In this blog, we will walk through how to pre-populate Marketing Cloud Account Engagement (MCAE) Form fields that you can use.

Why Pre-populate Form Fields?

Pre-filling Marketing Cloud Account Engagement (MCAE) form fields benefits both marketers and prospects:

1. Saves time for prospect, less typing, faster form completion.
2. Improves data accuracy by pulling existing values directly from Marketing Cloud Account Engagement (MCAE).
3. Enhances user experience by making forms feel more personal.
4. Increases conversion rates since shorter forms often result in higher submission rates.

Method We Use: Pre-populating Marketing Cloud Account Engagement (MCAE) Form Fields Using Merge Fields in the URL

In this method, we use Marketing Cloud Account Engagement (MCAE) merge fields to dynamically insert prospect data, such as their name or email, into the URL of a Marketing Cloud Account Engagement (MCAE) form.

When a prospect clicks on the personalized link, their details automatically appear in the form, eliminating the need for manual input.

This approach is one of the most common and effective ways to personalize form experiences for known prospects, especially when they access the form via a Marketing Cloud Account Engagement (MCAE) email.

Step-by-Step Guide to Pre-Populating MCAE Form Fields

Step 1: Create a Form and Add the Required Fields

Start by creating a new Marketing Cloud Account Engagement (MCAE) form and adding all the necessary fields you want prospects to fill out (e.g, First Name, Last Name, Email, Company, etc).

Step 2: Enable “Load Default Data”

In the Form Field Settings, click on “Load Default Data”

This allows Marketing Cloud Account Engagement (MCAE) to automatically prefill known prospect information from existing prospect records.

Also, make sure to select the following option:

Always display prefilled data, ensure that the field values appear on the form for known prospects instead of remaining hidden.

Step 3: URL Customization

Customize your Form URL for the pre-populating data.

We will append Marketing Cloud Account Engagement (MCAE) merge fields to the form URL so that when the prospect clicks on the link, their data automatically populates in the form fields.

Here we will add the tracking URL after the form URL.

Ex. Here in this case, we added the below tracking URL after the form URL

?first_name={{Recipient.FirstName}}&last_name={{Recipient.LastName}}&email={{Recipient.Email}}&company={{Recipient.Company}}

Step 4: Test the Form

Before launching your campaign, always test the setup to ensure everything works correctly.

1. Send a test email to a Marketing Cloud Account Engagement (MCAE) prospect record with known values.
2. Click on the personalized link from the email.
3. Verify that the Marketing Cloud Account Engagement (MCAE) form automatically pre-populates with your test prospect’s information.
4. Test in both incognito mode (for new visitors) and normal mode to confirm behavior for each scenario.

If the form doesn’t populate as expected, double-check the following:

1. The field names in the URL exactly match the External Field Names in Marketing Cloud Account Engagement (MCAE).
2. The merge field syntax (%%field_name%%) is correct.
3. The “Always display prefilled data” option is enabled for each field.
4.
