"Causality Engine has been a revelation for our business. We finally have a clear picture of what's working and what's not, allowing us to make data-driven decisions with confidence."

Frequently Asked Questions

How is Causality Engine different from Google Analytics?

Google Analytics primarily uses last-click or other rule-based attribution models. Causality Engine uses Bayesian causal inference to determine the *incremental* impact of each channel, showing you what sales would *not* have happened without that marketing touchpoint. It's the difference between correlation and causation.

Is this difficult to set up?

No. Setup is simple and requires no code. You connect your Shopify store and ad accounts (Meta, Google, TikTok, etc.) via a secure integration, and our models begin training immediately. You can have your first causal analysis within 3-5 minutes.

What if I have a small budget?

Causality Engine is even *more* critical for smaller budgets. When every euro counts, you cannot afford to waste it on channels that aren't driving real, incremental growth. Our €99 one-time analysis is designed for brands who need to make every marketing dollar work harder.

My brand is not in beauty, fashion, or supplements. Will this work for me?

While our expertise is deepest in these verticals, our causal models work for any Shopify-based e-commerce business with sufficient data. If you spend over 50,000 EUR/month on ads, we can likely provide significant value.
