Episode notes

In this episode of Marketing Analytics with Fexingo, Lucas and Luna dig into a blind spot most attribution models share: the long tail of hundreds of small, low-volume campaigns that collectively drive a surprising share of revenue. Using a concrete example of a mid-sized SaaS company running 500 experiments a quarter, they show how standard last-click models ignore the compounding effect of niche content, micro-influencers, and community posts. They discuss why the long tail is systematically undervalued, how to measure it without drowning in data, and the trade-offs of over-optimizing for the top 20 percent of campaigns. Along the way, they touch on the practical reality of marketing budgets in late 2026, when every dollar is being scrutinized, and offer a framework for reallocating spend toward the tail. If you've ever felt your attribution dashboard is lying to you, this episode gives you the language to explain why - and what to do about it.
