Why Last-Click Attribution Is Costing You Money

Too many marketers still rely on Google Analytics 4, Adobe, or other platforms that default to last-click attribution. On paper, this looks data-driven—but in reality, it creates blind spots.

Here’s why: last-click attribution gives too much credit to the end of the customer journey. That means channels like paid search get inflated results, while awareness-building efforts like CTV, display, or PR are undervalued.

The outcome? Budgets stay locked in familiar channels while high-performing opportunities get ignored.

The Problem with Overvaluing Paid Search

When paid search looks like the “hero” in your reporting, it’s easy to keep pouring money into it. But search spend eventually reaches a point of diminishing returns—where each new dollar drives fewer incremental conversions.

And guess what? Google will happily keep taking your money long past that point. Without the right measurement, you’ll never see when it’s time to shift budget elsewhere.

That’s why last-click reporting isn’t just inaccurate—it’s expensive.

The Challenge of Launching New Channels

Another limitation of last-click attribution is that it discourages exploration. When all credit goes to the final click, it’s hard to justify testing new channels.

How do you know if CTV, audio, or out-of-home are actually driving impact if their contributions never show up in your reports? Without a broader view, marketers remain trapped in the channels that feel safest—not necessarily the ones delivering the best growth.
