A/B Testing
That Actually Works
Run statistically rigorous experiments on your Shopify store without slowing it down. Test visual changes, prices, and layouts with zero flicker, automatic bot filtering, and results you can trust.

Built for Shopify stores
Zero Flicker
Anti-flicker technology ensures visitors never see the original page flash before the variant loads. Changes apply before the page renders, not after.
Trustworthy Statistics
Sequential testing (mSPRT) lets you check results anytime without inflating false positives. Bayesian analysis gives you clear probabilities, not confusing p-values.
Automatic Bot Filtering
Over 40% of ecommerce traffic is bots. We detect and filter them automatically so your experiment results reflect real human behaviour, not crawler noise.
How It Works
Create an Experiment
Set up your A/B test in minutes. Define what you want to change (text, images, layout, prices) and which pages to target. No coding required.
Traffic Splits Automatically
Visitors are deterministically assigned to variants using client-side hashing. No server calls, no latency, no flicker. Assignments are consistent across sessions.
Get Statistically Valid Results
Track conversions, revenue, and add-to-carts automatically. Our stats engine tells you when you have a winner with confidence, not guesswork.
Key Capabilities
Viewport-Aware Tracking
Only count visitors who actually see your change. For below-the-fold experiments, "visible users only" mode excludes visitors who never scroll to the element — giving you cleaner data and more accurate results.
Revenue Driver Explanations
Don't just see that revenue changed — understand why. The results page explains whether the lift comes from more people buying, higher cart values, or both, with insight tags highlighting key learnings.
Configurable Decision Standards
Choose your confidence level: Directional (90%), Standard (95%), or High Confidence (99%). See how results would look under each standard. Locks when the test starts to prevent cherry-picking.
Server-Side Price Testing
Test different prices using Shopify Functions (Cart Transform). Prices change server-side so there's zero flicker and no way for customers to see the original price.
Conversion Funnel
Visualise the full journey from page view to purchase. See exactly where visitors drop off and which funnel stage has the biggest opportunity for improvement.
Google-Style Experiment Layers
Run multiple experiments simultaneously without interference. Overlapping layers ensure each experiment gets clean, uncontaminated data.
CUPED Variance Reduction
Pre-experiment visitor data reduces statistical noise, meaning experiments reach significance up to 40% faster. Less waiting, faster decisions.
Live Preview Toolbar
Preview any variant directly on your live store. Switch between control and treatment, see real-time viewport detection, and verify experiments without affecting live traffic.
Scheduling & Email Alerts
Set active hours for time-sensitive experiments. Get notified when experiments reach significance, when traffic imbalances are detected, or receive daily digests.
About Exceedity
Exceedity A/B is built by Exceedity Ltd, a UK-based advisory firm that works with ambitious ecommerce founders. With 60+ years of combined experience across retail, ecommerce, and consumer brands, we built this tool because most A/B testing platforms are either too expensive, too complex, or produce unreliable results for Shopify stores.
Exceedity A/B is purpose-built for Shopify with bot filtering, safe peeking statistics, and zero-flicker mutations. No more guessing whether your results are real.
