The Hidden Power of Indirect Impact in Marketing Measurement
Most marketers are flying blind to one of the most powerful forces in advertising: indirect impact.
Indirect impact is what happens after someone sees your ad but doesn’t click. It’s the lift that unfolds over days or even weeks, shaping future conversions and driving incremental demand that click-based attribution never captures.

If you’re relying on last-click or click-based models, here’s what you’re missing:
- The long-term effect of your media, also known as ad stock
- The synergies that occur when channels run together
- The real incremental value of what’s driving conversions
Without measuring these effects, marketers undervalue their campaigns, misallocate budgets, and miss opportunities to secure more investment.
Ad Stock: The Long-Term Effect of Media
Not all impact is immediate. Some ads leave a lasting impression that continues to influence consumer behavior days or weeks later. This lingering effect—called ad stock—is critical to understanding the true value of your media.
For example, a connected TV campaign may not generate instant conversions but will drive awareness that later boosts search, display, or even in-store sales. If you only measure clicks, you’ll miss this halo effect entirely.
Media Synergies: When 1 + 1 = 7
Another overlooked factor is media synergies—the multiplier effect when two channels run together. For instance, display and CTV working in tandem may deliver far more impact than either channel alone.
Standard attribution models can’t detect these synergies. They’re hidden in the noise, leaving marketers to underestimate performance and cut spend on channels that are actually pulling extra weight.
