Reasons CMOs require a new framework for accountability.

      Marketing leaders now have more data at their disposal than ever, yet demonstrating the business impact of advertising is becoming progressively harder. With budgets under increased scrutiny and finance departments demanding clearer proof of return on investment, many chief marketing officers are realizing that conventional performance metrics no longer address the inquiries being posed in the boardroom.

      Tal Jacobson, CEO of Perion, argues that the challenge extends beyond mere measurement; it is fundamentally an infrastructure issue. He elaborates on why current marketing technology stacks struggle to provide true accountability, how artificial intelligence is transforming campaign execution and assessment, and what CMOs must do to showcase business outcomes rather than just marketing activities.

      There’s been considerable discussion about CMOs facing pressure. You seem to believe that the issue is more entrenched than most recognize. Why is that?

      The discourse often halts at the symptoms: CMOs are under pressure, budgets are stagnant, and CFOs demand proof. We agree on these points. However, no one considers why years of investment in marketing technology hasn’t resolved the problem.

      The core issue is structural. We have developed an entire industry focused on measuring activity rather than outcomes—clicks, impressions, reach, and frequency are not true business results but merely proxies. For a long time, the C-suite accepted these metrics, but that era has ended.

      CFOs have become increasingly demanding regarding advertising expenditures. They have witnessed budget growth and now wish to understand what those budgets have actually accomplished. Most CMOs, through no fault of their own, do not have a credible response.

      Why is that the case? These organizations have sophisticated data infrastructures.

      The data is indeed present. The challenge lies in its fragmentation across numerous systems, each optimized to highlight its own successes.

      Search claims credit for conversions, social claims awareness lift, and display asserts assistance. When you aggregate attribution across channels, you may "prove" three times the revenue you actually generated. Every platform is motivated to demonstrate its own value and none are incentivized to present the complete truth.

      So when a CMO approaches a CFO, they bring figures that don’t align, derived from systems not designed to reconcile. It appears to be a measurement problem, but it is fundamentally an infrastructure issue.

      What is the CFO specifically asking that the CMO cannot answer?

      The most challenging question in advertising: Did this spending lead to anything that wouldn’t have occurred otherwise?

      That question addresses incrementality and is one that the standard measurement setup was never designed to answer. You can demonstrate that a conversion took place, but it's not easy to show that the conversion was a result of the spending as opposed to occurring independently or in spite of it.

      Consider a loyal customer who was going to purchase regardless, or a seasonal spike that was inevitable, or a market trend that was heating up without your campaign. Remove those factors, and what remains? That's what the CFO is keen to know, and most marketing organizations genuinely lack that answer.

      Is this an issue with technology or organization?

      It’s both, but technology must come first. You cannot address an organizational accountability issue if the underlying infrastructure cannot produce the necessary evidence for accountability.

      Currently, CMOs are being asked to operate with CFO-level precision using tools designed for a different era and standard of proof. This mismatch is the problem, as it’s not that marketers lack intelligence or discipline; it's that the infrastructure they are using was created to run campaigns, not to generate business-level evidence.

      The industry has promised enhanced measurement for years. What has genuinely changed?

      What’s changed is the cost of inaccuracies. When ad budgets were on the rise, imprecise measurement was manageable. No one scrutinizes a budget that’s yielding growth. Now, with flat budgets and tougher growth prospects, every dollar must justify its existence against competing business priorities.

      Additionally, AI has transformed the landscape—not just as a buzzword, but as a practical execution infrastructure. The capacity to process signals across channels in real time, optimize against business outcomes rather than just platform metrics, and differentiate real growth from baseline noise is now technically feasible in a way it wasn’t five years ago.

      However, there remains a gap between what can be technically achieved and what most marketing organizations currently employ.

      What does a CMO need to engage in a CFO discussion with confidence?

      Three essentials: a unified source of truth across channels rather than channel-level reports aggregated after the fact; incrementality measurement that withstands scrutiny instead of mere attribution; and the capability to demonstrate real-time optimization rather than relying on post-campaign reports weeks later.

      These are not aspirational goals; they are fundamental requirements for the conversations CMOs must have in 2026.

      How does Perion fit into this picture?

      We developed Perion One specifically to address this issue. Our central premise is clear: fragmentation impedes accountability. If your execution is spread across various channels, your measurement will suffer as well. Unified evidence cannot emerge from a disjointed infrastructure.
