SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Run statistically rigorous A/B tests to determine whether product page, checkout, or pricing changes actually move conversion and revenue, avoiding false positives from underpowered or early-stopped experiments.

Core Features & Use Cases

Platform guidance: Recipes for Shopify, WooCommerce, BigCommerce, and custom/headless storefronts including tools like Intelligems, Convert, Nelio, GrowthBook, and LaunchDarkly.
Sample size planning: Walkthroughs and examples for calculating per-variant sample sizes, selecting power and significance, and enforcing stopping rules.
Server-side assignment & pricing tests: Recommendations for deterministic, sticky variant assignment to avoid price flicker and ensure consistent customer experiences.
Analysis and guardrails: How to report revenue per visitor, measure guardrail metrics (returns, cart abandonment), and interpret significance without p-hacking.

Quick Start

Run an A/B test comparing a checkout variant to control, pre-calculate the required sample size for the desired MDE and power, and evaluate results by revenue per visitor after the minimum sample is reached.

Frequently Asked Questions about ab-testing-ecommerce

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I calculate sample size for an A/B test on my ecommerce pricing page?▼

Calculate sample size for A/B testing pricing pages by pre-determining the minimum detectable effect and statistical power required per variant to avoid underpowered experiments and false positives. This ensures you capture true revenue impact without stopping tests prematurely.

How do I prevent price flicker when running Shopify A/B tests?▼

Prevent price flicker during Shopify A/B tests by using deterministic server-side variant assignment to ensure sticky pricing experiences. This approach keeps pricing consistent for each customer across sessions without loading delays.

Does this approach support A/B testing on WooCommerce and BigCommerce storefronts?▼

Yes, A/B testing on WooCommerce and BigCommerce storefronts is fully supported with specific platform recipes. You can run controlled experiments for checkout flows and pricing changes across these platforms, as well as custom headless storefronts.

How do I interpret statistical significance and revenue per visitor after an A/B test?▼

Interpret statistical significance and revenue per visitor by evaluating guardrail metrics like cart abandonment and returns only after reaching the minimum pre-calculated sample size. This prevents p-hacking and ensures the reported conversion impact is valid.

When should I not use client-side A/B testing for ecommerce checkout optimization?▼

Avoid client-side A/B testing for ecommerce checkout optimization when running pricing experiments, as it causes price flicker and inconsistent user experiences. Use deterministic server-side variant assignment instead to maintain sticky pricing and accurate conversion measurement.
