FAQPage Schema
How do I calculate cross-channel ROAS and MER for my ecommerce store?

Cross-channel ROAS and MER are calculated by standardizing marketing spend data across platforms to reveal true efficiency and break-even metrics. This analysis normalizes platform and first-party data to generate a unified weekly performance dashboard.

What is the difference between platform ROAS, first-party ROAS, and blended ROAS?

Platform ROAS uses attribution data from the ad network, while first-party ROAS uses your ecommerce store's own data. Blended ROAS combines normalized data across all channels to calculate true marketing efficiency and guide budget pacing.

Can I use marketing spend analysis with Shopify, WooCommerce, or BigCommerce?

Yes, marketing spend analysis works with Shopify, WooCommerce, BigCommerce, and custom stores. It consolidates scattered channel data to track break-even points and alert you to underperforming channels for budget reallocation.

How do I normalize attribution data to avoid misattribution in marketing spend?

Attribution data is normalized by standardizing varied channel metrics into a unified format. This process prevents misattribution and waste by comparing first-party and platform data to reveal true cross-channel performance.

What's the best way to generate a weekly marketing budget pacing dashboard?

The best way to generate a weekly budget pacing dashboard is to consolidate cross-channel spend data and apply break-even calculations. This surfaces channels that exceed break-even and alerts on underperformers to inform reallocations.

Why does my platform ROAS look healthy but my overall marketing budget is not profitable?

Platform ROAS can look healthy while overall budgets fail due to misattribution. Comparing platform ROAS against first-party and blended ROAS reveals true efficiency, calculating your actual break-even point to highlight hidden waste.
