Full-Funnel ROI Is Becoming the New Battleground for DTC Growth

For years, DTC brands have been told to “invest in brand.” But when acquisition costs climb and CFOs demand clearer accountability, even the most sophisticated teams face the same challenge: how do you measure what has traditionally been “unmeasurable”?

Large-scale brands: from Ulta Beauty and Shein to leading marketplace retailers, have all run into the same problem. When CACs fluctuate and budgets tighten, the ability to quantify the influence of top-of-funnel activity becomes a board-level conversation. Leaders don’t just want to know if awareness campaigns “worked”; they want to know how those impressions lowered CAC, increased revenue, and ultimately delivered incremental growth.

That’s why full-funnel measurement is rapidly becoming the strategic battleground for performance teams and ad platforms alike. As TikTok continues to evolve beyond a discovery engine into a full-commerce environment, platforms must show that they don’t only drive TOF engagement, but also meaningfully shape downstream revenue outcomes.

In NYC, and free @08:30 AM ET, Wed December 3rd? Request a seat at ClickZ’s private breakfast roundtable, hosted in partnership with TikTok and Fospha. The event will bring together senior eCommerce and retail brand leaders to unpack what the next generation of performance measurement looks like, specifically through the lens of TikTok’s Smart+ and GMV Max ecosystem. The conversation centers on a shared objective: connecting brand-led activity to provable, blended performance.

For advertisers, the stakes are high. Full-funnel ROI isn’t just a reporting improvement; it’s a competitive advantage. When teams can quantify how brand impressions influence mid- and lower-funnel performance, they can allocate budgets with far greater confidence -often uncovering profitable scaling opportunities that traditional attribution models overlook.

This is where independent measurement partners enter the picture. Solutions like Fospha help brands unify first-party, platform, and conversion data into a coherent, privacy-safe model. Rather than replacing platform analytics, Fospha provides the missing context: how upper-funnel exposure contributes to incremental conversions, improved efficiency, and reductions in blended CAC.

That neutrality is key. It enables brands to validate the full-funnel impact of platforms like TikTok with greater confidence, and it also helps platforms demonstrate their influence beyond last-click performance – unlocking not only direct-response budgets, but brand budgets as well.

As 2026 approaches, one thing is increasingly clear: the brands that win will be the ones that can measure the “unmeasurable”. Full-funnel performance isn’t a buzzword; it’s a financial framework. And for leaders gathering at ClickZ’s roundtable, the mission is the same – turn brand investment into a measurable, defensible growth engine.
