What is Halo?
Halo's unified measurement captures sales across DTC and marketplaces like Amazon and TikTok Shop, aligning teams with consistent cross-platform reporting so they drive the best business outcome overall.
Measurement for every marketplace
42% of Amazon sales are influenced by non-Amazon media. However, most measurement tools only show how ads drive DTC conversions, meaning the impact of paid media spend on marketplace sales is missed.
Fospha is the only platform that quantifies cross-channel halo effects daily using impression measurement within our Bayesian MMM, allowing you to optimize continuously rather than rely on one-off experiments.
Halo bridges this gap by connecting web media spend to outcomes across all major destinations - your site, Amazon, and TikTok Shop - giving you a complete view of your marketing’s impact.
Unified, cross-channel view
Fospha provides marketers with a single view of sales across DTC and marketplaces like Amazon and TikTok Shop - unifying measurement that reflects real customer behavior.
Halo measures Unified ROAS, Unified CPP, and Unified Revenue - all the way down to ad level - making halo effects not just visible, but actionable for both DTC and Amazon teams.
Campaigns get credit whether the purchase happens on your site or within a marketplace.
A shared source of truth across teams
Halo's cross-platform reporting de-silos both DTC and Amazon teams, fueling smarter budget decisions and stronger business outcomes.
DTC teams can protect and scale budgets when performance looks underreported in dashboards, while Amazon teams can unlock incremental marketplace growth by proving which external campaigns drive their sales.
Teams are empowered to align on budgets, prove the value of upper-funnel media, and optimize for total business revenue instead of channel-by-channel wins.
Drive total business growth
Traditional measurement undercredits DTC media because it only connects DTC ads to DTC sales - missing the halo effects on Amazon and other marketplaces.
Halo surfaces their hidden value, showing how your marketing spend on channels like Meta, TikTok, YouTube lift both DTC and Amazon revenue.
Brands leveraging Halo optimize toward total business revenue by accounting for both DTC and marketplace sales, doubling down on campaigns that create demand and drive growth for their business.
