Prime Day: Big Win or Wakeup Call?

Prime Day 2025 smashed records. Extended to four days, it generated $24.1B in U.S. online sales — a 30% year-on-year surge.

But as brands dive into retros and kick off BFCM planning, one question looms: what actually worked? Which channels truly drove conversions — and how can we know?

That’s where understanding cross-channel halo effects becomes essential. New research from Fospha sheds light on how different platforms influence conversions across both DTC sites and Amazon.

TikTok leads with an 80% uplift in ROAS when Amazon sales are included, followed by YouTube (48%) and Meta (46%). These platforms ignite discovery and spark intent that may convert later — whether on your DTC site or on Amazon. Without visibility into cross-channel halo effects, that impact remains invisible.

👉 Explore Fospha’s Halo Effect research to uncover what really drove your Prime Day results.
