Project Goal

Streamline a complex digital ecosystem delivering an enriched experience for patients that is measurable for CDI.


CDI has a small but growing digital marketing team. A flexible engagement was required, one where we could quickly make the biggest impact given shifting timelines and priority projects.

With the CDI team focused on design and content, the development team focused on the site build, and a fast approaching deadline for the new site launch, it was imperative that we monitor blind spots; quickly and thoughtfully discussing SEO implications at critical moments in the project.


  • Elevate and modernize the internal conversation at CDI around analytics and measurement
  • Create a single source of truth for CDI’s digital measurement
  • Determine the ranking value of each of CDI’s 190 existing domains
  • Transfer the significant ranking value of each legacy domain to the new unified domain –
  • Deliver a measurement solution that would allow CDI’s marketing team to scrutinize metrics with accuracy and confidence, creating long-term efficiencies and improved business decisions
  • Understand the digital value of existing traditional marketing tactics: print, radio, out-of-home and partnerships with local professional sports teams

  • Implemented Google Tag Manager to empower CDI’s marketing team to deploy common tracking requirements without the need for a technical resource.
  • Developed a process to ensure traditional marketing efforts were connected to digital goals.
