How Fospha Measures (Simple Version)

The Problem We Solve

Most measurement tools only see part of the picture. Google Analytics credits the last click. Meta says it drove the sale. Google says it drove the sale. TikTok says it drove the sale. They cannot all be right.

Meanwhile, brand-building channels that create awareness get zero credit because nobody clicked an ad — they just saw it and bought later.

Fospha solves this by measuring everything — clicks, impressions, and marketplace sales — in one unified view.

The Glassbox Approach

Unlike "black box" models, Fospha is a glassbox. Full visibility into every model layer, validation metric, and daily retraining step. Transparency builds trust.

The Model Waterfall — 6 Steps

Step 1: Start with GA4 Last-Click Data — Where most tools stop. Heavily biased toward search.

Step 2: Click Measurement (Multi-Model Ensemble) — Four independent models checking each other's math.

Step 3: Reconciliation — GA4 undercounts. We reconcile against the ecommerce source of truth.

Step 4: Post-Purchase Attribution — Discount codes and surveys credit influencers, podcasts, word-of-mouth.

Step 5: Daily MMM Impression Measurement — The key differentiator. ML measures true impact of impressions and views.

Step 6: Halo — Marketplace Measurement — Amazon + TikTok Shop sales connected to paid media.

The Result

A fully reconciled, cross-channel, daily, ad-level view of marketing performance — trusted by marketing, finance, and leadership.

Key Takeaway

Fospha builds a complete picture — from the first impression to the last click to the Amazon purchase — every single day.
