Prove brand builds the growth you've always known it has

Glow measures the early signs of brand demand while your campaign is still running, so you can show your CFO it's working before the revenue arrives.

Fospha's solution

What is Glow?

Glow uses causal modeling to connect awareness spend to the signals buyers make when they're considering your brand, and delivers one number: the Brand Impact Ratio, showing how much demand each channel is building relative to what you spend there.

Brand spend is judged by rules designed for performance

Brand campaigns target future buyers, so the payoff isn't immediate. But that's not a defense you can make when every other campaign has a clear metric of success.

Measure the demand your campaigns will capture tomorrow

Glow tracks two signals that move weeks before revenue does: branded search impressions and engaged sessions, showing which channels are growing your pool of future buyers and lowering the cost of every other campaign.

Put a number on what brand is building

Glows output, the Brand Impact Ratio shows how much brand demand each channel generates relative to what you spend there. Where ROAS shows you what you're converting today, the Brand Impact Ratio gives brand teams a number for how much demand they're building for tomorrow.

How Glow works

Not based on perception or three months of lag. Just the causal link between spend and demand, fresh enough to act on.

Causal, not correlational

Glow uses two years of GA4 and ad platform data to establish the causal relationship between awareness spend and early brand signals, not just whether they move together.

The signals between spend and sale

Glow tracks branded search impressions and engaged sessions: the steps customers take before they convert, surfacing weeks before revenue does.

The Brand Impact Ratio

Glow delivers one number per channel: how much brand demand it's building relative to what you're spending there. The higher the Brand Impact Ratio, the more demand you're creating for your money.

Defend, redirect, and grow

The output gives brand teams the evidence to defend spend, reduce investment in low-signal channels, and grow the ones building demand most efficiently.

Use Glow for

Brand budget defence

Give finance the evidence they need before they ask for it. Brand is usually the first budget cut when targets slip, not because it isn't working, but because most teams can't show it is.

Early campaign signals

See whether a campaign is building demand while it's still running, so you can scale what's working without waiting for post-campaign surveys to come through.

Reviving channels you couldn't justify

Since Glow looks back at two years of platform and GA4 data, you can make the case for channels you always knew were driving growth but had no metric to defend.

How do I know your model is accurate?

We take accuracy seriously. Our model undergoes daily quality checks to ensure reliable, fair measurement you can trust. Here's how we ensure accuracy:

- Data Validation First: Before anything enters our model, we verify your tracking is consistent across platforms, identify any gaps between channels, and run daily checks to confirm outputs align with expected patterns.

- Historical Back-Testing: We prove our value by showing how our model would have accurately predicted your past performance trends, giving you confidence our recommendations are reliable.

- Outlier Capping: During major sales events like Black Friday, ad platforms typically over-claim credit. Our system automatically adjusts the outputs on high-traffic days to maintain a fair picture of what's really driving results.

Is Fospha privacy safe?

Yes, Fospha is built for privacy-first measurement, today and in the future.

For 10+ years, we've led the shift away from pixel-based tracking, building our solution to meet global privacy standards like GDPR, CCPA, and iOS14+, and preparing for changes like Google’s Privacy Sandbox.

Here’s how we do it:

No third-party cookies or user-level tracking: Our model doesn’t rely on personal identifiers or outdated tracking methods

- Privacy-first by design: Fospha combines always-on measurement signal with Daily MMM to restore visibility lost to privacy changes—without compromising compliance

- Proven compliance: Trusted by global brands across the US, UK, and EU, Fospha meets the highest privacy standards

How is Fospha different from traditional MTA, MMM, and other marketing measurement solutions?

Fospha uniquely combines the best of both worlds by unifying always-on measurement signal with Daily MMM - something our competitors simply don't offer.

While platform-native dashboards miss upper-funnel impact due to signal loss, and traditional MMM lacks the speed and granularity for daily decisions, we deliver:

- The granular, ad-level measurement insights for tactical optimization

- The predictive power and total channel visibility of our Daily MMM, fairly crediting both demand generation and capture channels

Our unified approach, refined through 10+ years of working with hundreds of brands, corrects the common measurement bias toward last-touch channels - properly valuing the complete channel mix from awareness to conversion.

Which channels does Fospha measure?

Fospha measures your entire channel mix, from brand awareness to conversions, giving every channel fair credit using privacy-safe Daily MMM.

We cover everything that drives growth - across web, app, and Amazon - and unify it into a single, unbiased view.

What sets us apart:

- Halo Effect: Reveal how Meta, TikTok, and Google ads drive sales on Amazon - with unified ROAS across DTC and marketplace

- TikTok Shop: Track in-app and on-site purchases together, giving you full visibility into TikTok performance beyond what Google Analytics can capture
