Marketing Mix Modelling and Incrementality Testing
For over a decade, digital marketers relied on last-click attribution to decide where to spend. That model was always flawed, and now it is collapsing. Privacy regulations, cross-device behaviour, and walled gardens have made click-path tracking unreliable at best and misleading at worst.
Marketing Mix Modelling (MMM) and incrementality testing offer a fundamentally different approach. Instead of tracking individual users, these methods measure the true causal impact of each channel on business outcomes. Brands adopting MMM are discovering that 15 to 30 percent of their media spend was being allocated to channels that looked good on a last-click report but contributed far less actual revenue.
The shift is not theoretical. Google, Meta, and major holding companies have all invested heavily in MMM tooling over the past two years. The methodology that was once reserved for enterprises with million-dollar research budgets is now accessible to mid-market teams willing to invest in proper measurement infrastructure.
