RedTrack vs Causality Engine
RedTrack is best for media buyers and ecommerce teams tracking paid traffic across ad networks. Choose Causality Engine when you need a defensible per-channel read before a budget decision, from the GA4 export you already have.
€99 once, excl. VAT. Keep RedTrack; use us as the causal second opinion.
Side by side. Every fact sourced.
Short answer: Keep RedTrack. Causality Engine is not a replacement for it: it installs nothing and reads the GA4 export you already have, so it adds a read of what each channel caused on top of RedTrack's click and conversion tracking with a tracking script, postbacks and conversion APIs, for €99.

Causality Engine installs nothing on your site. It reads the GA4 export you already have, so it runs on top of any tool here without touching its setup. The one condition: GA4 runs on your store too. “Not stated” means we could not find it on the vendor's own pages or listings on 12 October 2026; it does not mean the feature is missing.

Competitor pricing is each vendor's publicly listed pricing as read on the date shown, and it changes without notice: verify on the vendor's own site before relying on it. Vendors without a public price are marked as such. Comparisons set Causality Engine's one-time €99 analysis against subscription models.
Where RedTrack falls short
- Click and conversion tracking records which touchpoint was present, not whether the sale would have happened without it
- Ecommerce plans are priced on tracked revenue
- Needs a tracking script on the store
What Causality Engine does differently
- No pixel and no tag. It reads the GA4 export you already have, where RedTrack needs its own tracking on the store.
- What each channel caused, next to what last-click gave it, with a data-health score on every channel.
- The first number 1 to 2 minutes after the upload, on whatever GA4 history you export; 12 months or more reads best.
- €99 once, excl. VAT. Pro is €299 a month, billed monthly, cancel any time.
- Full refund within 30 days, no questions asked. You keep the read.
