Platform-reported attribution is always biased — Google Ads takes credit for conversions Meta influenced, and vice versa. Building your own attribution model in BigQuery gives you an independent view. We implement attribution models ranging from simple rule-based (last-touch, linear, time-decay, position-based) to data-driven Shapley Value models using your GA4 clickstream and conversion data. The result is an attribution model you own, understand, and can adjust.

Frequently Asked Questions

Platform attribution is self-serving — each platform takes maximum credit. Building in BigQuery gives you an independent model using your own data, not each platform's black box algorithm.
GA4 event data (user journey events with campaign parameters) and conversion events, plus ad spend data by channel. We help ensure your GA4 export has the required data.
More accurate than single-platform attribution, but limited by the same fundamental challenge: touchpoints must be trackable (consent, cookies). Server-side tracking improves touchpoint capture.
A game-theory concept where credit is distributed based on each channel's marginal contribution to conversions across all observed paths. It's the most mathematically fair model available.
Not directly in real-time. But BigQuery attribution results can inform manual budget reallocation decisions, and can feed Google Ads enhanced conversions if implemented.
