The Context

CollaborateMD needed a scalable way to embed Marketo forms into their WordPress marketing site while maintaining tracking accuracy and branding consistency.

The existing iframe-based implementation limited customization, broke visibility into key user interactions, and prevented reliable event tracking such as form submissions and abandons.

The Challenge

The existing form system introduced several constraints:
  • Iframe-based embeds prevented custom event tracking
  • No visibility into form abandon or interaction behavior
  • Limited control over branding and styling consistency
  • No standardized approach for lead routing workflows
  • Marketing teams dependent on engineering for form updates

The Approach

Reusable WordPress Form Block

Built a custom ACF-powered WordPress block to dynamically embed Marketo forms in a reusable, modular structure across marketing pages. Using theme options and values ACF makes it easily reusable to marketers and other teams.

Native Theme Styling Integration

Removed default Marketo iframe styling and restructured forms to inherit native site styles, ensuring consistent branding across all form instances.

Custom Form Follow-Up Options

Implemented the ability to choose within the block if a message, thank you page, or ChiliPiper should be loaded upon successful form submission. This made the block extremely reusable, and easy for other teams to implement.

Event Tracking & Analytics Restoration

Using the Marketo form API, I was able to enable custom GTM data layer events for submissions, views, and form abandon behaviors previously blocked by iframe constraints.

ChiliPiper Scheduler Workflow Integration

Integrated an option to load ChiliPiper scheduler directly into the form submission workflow to enable scheduling of demos with sales reps while still capturing Marketo form leads after successful form submissions.

Cross-Functional Validation

Partnered with Lifecycle Marketing and RevOps teams to validate tracking accuracy, ensure workflow alignment, and confirm lead routing behavior across campaigns.

The Outcomes

Improved performance via async form loading strategy

Implemented accurate submission, views, and abandon event tracking

Eliminated iframe limitations blocking custom branding

Standardized lead routing across marketing campaigns

The Reflection

This project reinforced the importance of treating marketing forms as functional product surfaces rather than embedded widgets, particularly when they directly influence attribution accuracy, lead routing reliability, and campaign performance measurement.
