A/B Testing & CRO Checker

What this tool detects

This checker scans any store's page source for script signatures from 14 A/B testing, heatmap, session recording, and conversion rate optimization platforms. It identifies which tools are active without requiring any account access.

Why A/B testing matters for ecommerce

The best-converting ecommerce stores run continuous experiments. A/B testing lets you make evidence-based decisions about product page layouts, CTA copy, pricing displays, checkout flows, and more — instead of guessing. Even a single well-designed experiment that lifts CVR by 5% can mean thousands in annual revenue.
