Case Study: How SimplePractice Improved Efficiency with Rockerbox MMM

As SimplePractice scaled spend to $25M+ annually across search, Performance Max, social, and partnerships, efficiency became harder to maintain. Blended CAC was rising, and channel-level tests gave conflicting answers.

“We couldn’t confidently answer the biggest question: Where is our next opportunity to invest that gives us the biggest upside with the most efficient use of spend?” - Taj Anderson, Sr. Marketing Analyst-Business Analytics, SimplePractice

The team needed a way to identify which channels were truly incremental and make confident, data-driven budget allocations.

How Rockerbox Helped

With Rockerbox’s Marketing Mix Modeling (MMM), SimplePractice gained clarity on where to scale and where to pull back:

• Scaling social with confidence: MMM revealed untapped room in social, a channel that had been difficult to measure and optimize.
  
  
• Smarter cross-channel tradeoffs: MMM helped the team weigh diminishing returns in Performance Max against opportunities in other channels.
  
  
• Guidance on hard-to-track channels: MMM showed that partnerships needed more time and sustained investment before their impact could be fully measured.
  

Actionable Results

With Rockerbox MMM insights, SimplePractice reallocated spend and saw significant and measurable improvements:

• 30% reduction in Social & Performance Max CAC
  
• 5–10% overall conversion lift
  

“We were able to increase spend while reducing CAC overall. That’s the kind of outcome we love….costs less and generates more revenue.” -  Taj Anderson, Sr. Marketing Analyst-Business Analytics, SimplePractice

Why SimplePractice Needed MMM

MMM enabled SimplePractice to move from fragmented channel testing to a holistic measurement strategy. The team can now confidently answer where the next dollar should go, align executives on channel impact, and expand into top-of-funnel strategies without wasted spend.

“MMM is a foundational step. Once you move from single-channel to cross-channel marketing, MMM becomes essential. It not only improves today’s decisions, it sets you up for next-gen marketing.” - Taj Anderson, Sr. Marketing Analyst-Business Analytics, SimplePractice
