By measuring media’s impact against multiple metrics — beyond just sales — marketers gain deeper insights into what’s working, where to invest, and how to drive sustainable growth. Facing rising acquisition costs, AI-driven campaigns, evolving consumer behavior, and budget allocation challenges, marketers need to be taking advantage of the most advanced incrementality testing capabilities to guide their ad spend decisions.
Here’s why Multi-KPI testing is a must-have for 2025, and how it can transform your marketing strategy.
A Quick Overview of Multi-KPI Testing
Multi-KPI testing goes beyond measuring media’s impact against sales — it’s about analyzing the total incremental effect of a marketing channel across multiple key performance indicators (KPIs). This gives marketers a more comprehensive view of what’s working and what’s not so they can allocate budgets more effectively.
Using a Facebook ad placement as an example, instead of just tracking the ad’s incremental impact on orders, a Multi-KPI test may also evaluate the following:
- What percentage of those orders are from new customers?
- How does that compare to what Google Ads is driving?
- Are those new customers buying high-LTV products, or are they purchasing one-off, lower-value items?
- Are those ads driving lift in brand awareness and consideration?
The Benefits of Multi-KPI Testing
Incrementality testing has been a go-to method for measuring channel effectiveness for smart marketing organizations. But with customer acquisition costs (CAC) surging 60% since 2019, more advanced techniques like Multi-KPI testing can help reveal even more insights about media performance so marketers can maximize the performance of their ad dollars. In other words, while single-conversion point testing can help measure sales driven by marketing, it doesn’t provide a full picture.
Here are two examples of how Multi-KPI testing answers marketers biggest questions:
Example 1: Why High-Lifetime Value Customers Matter
Not all customers contribute equally to long-term revenue. Brands must differentiate between low-value deal-seekers and high-LTV buyers. Multi-KPI testing ensures marketing efforts attract repeat customers who generate sustainable growth. Is your marketing attracting customers who will continue to purchase from your brand over time?
Example 2: Understanding AI-Driven Campaigns
AI campaigns like Facebook’s Advantage+ and Google’s PMAX complicate measurement by blending prospecting, retargeting, and retention into one. This makes it hard to tell exactly how each campaign is performing. Marketers need structured testing to decipher AI-driven results.
Best practices include:
- Establishing baseline performance through multi-tactic testing
- Monitoring AI campaigns closely to separate their true impact
- Running continuous tests throughout the year to refine strategy
- Acknowledging that AI campaigns may not be delivering expected results
Building a Framework for Multi-KPI Testing
Once you’ve gathered insights from your testing, you need to build a framework that connects these findings to decision-making and financial outcomes. Either by working with a partner like Measured or managing this in-house, marketers are better able to understand channel performance and make informed financial decisions that drive ongoing growth.
Multi-KPI testing insights should inform three key frameworks:
- Measurement Framework: Integrate testing into media mix models and attribution strategies.
- Financial Framework: Align testing with budgeting and revenue goals.
- Decision Framework: Set marketing budgets based on performance data and LTV expectations.
Conclusion
Multi-KPI testing is essential for navigating today’s multi-channel marketing landscape. By testing across multiple dimensions and structuring insights into a decision-making framework, brands can optimize their marketing spend for long-term, profitable growth.
