Shopify split testing that replaces guesswork with tested proof
Every change you make to your Shopify store is a hypothesis. Redefine runs structured split tests that validate those hypotheses with statistical confidence, then deploys winners that compound your revenue month over month.

Making changes without testing is a coin flip with your revenue
Most Shopify stores ship design and copy changes based on opinion. Structured split testing replaces that pattern with measurable proof.
Watch Shopify experimentation services run in real time
This is what your experimentation dashboard looks like when Redefine is running your program. Every test is live, tracked, and attributed to revenue before a decision is made.

Priority #1Simulated data for illustration. Your actual dashboard reflects your store's live experiments, real traffic, and statistically verified results.
Every kind of Shopify experiment your store needs
Redefine runs the full range of Shopify experimentation types. Each service is matched to the funnel layer with the highest revenue leverage for your current store maturity.
Product Detail Page Split Testing
Product detail pages are the highest-leverage testing surface. Redefine tests hero image sequencing, price anchoring, trust badge placement, and variant selectors against your live traffic.
Checkout Optimization Tests
Express pay placement, field count reduction, trust signals at payment step, and upsell timing. Checkout tests deliver the fastest revenue per test of any Shopify experiment type.
Homepage and Hero Tests
Value proposition framing, hero image selection, social proof placement, and primary call to action wording. These tests improve the quality of traffic you send downstream to product detail pages and cart.
Social Proof and Review Tests
Star rating position, review snippet length, verified buyer badges, and photo review versus text-only. Trust signals are often tested later but produce outsized product detail page conversion gains.
Shopify Landing Page Testing
Paid traffic landing pages, campaign-specific pages, and collection landing pages. Tests include layout, headline, proof placement, and call to action design to improve cost per acquisition directly.
Cart and Upsell Experimentation
Cart drawer layout, upsell tile design, cross-sell recommendation position, and cart abandonment triggers. These tests compound conversion rate gains with average order value gains in the same funnel layer.
Structured testing that tripled a brand's revenue
Regional craft beer brand with a strong heritage identity expanding their direct-to-consumer channel on Shopify through data-driven optimization.
Disconnected systems across point of sale, ecommerce, and customer data were limiting visibility into performance. The Shopify store needed conversion and user experience improvements, while marketing lacked the advanced segmentation and predictive insight to capitalize on existing customer demand.
A unified digital strategy across analytics, commerce, payments, and marketing. Power BI was integrated with Toast, Shopify, and VIP to centralize data and provide real-time reporting. Secure payment gateways were implemented with Stripe and PayPal. The Shopify store received full user experience optimization. Klaviyo advanced segmentation and predictive flows were built to turn customer data into recurring revenue.
Centralizing analytics across all sales channels was the unlock that made optimization possible. Without unified data, you cannot run experiments. You cannot measure what you cannot see.
What most Shopify conversion testing partners skip
Running A/B tests and running a structured experimentation program are two different things. The difference shows up in your results after six months.
Revenue-impact ranking before any test design
Most testing partners build the test first and measure impact after. Redefine ranks every opportunity by estimated revenue impact before a single test is scoped, so your velocity goes to the highest-return experiments first.
Shopify-native variant builds, not JavaScript overlays
Test variants built with overlaid JavaScript create Core Web Vitals failures and speed regressions that distort your results. Redefine builds variants in Liquid and Shopify 2.0 sections so test performance matches production performance.
Monthly revenue attribution, not activity reports
You receive a monthly statement that answers one question: how much revenue did this program generate this month? Test activity, win rate, and projected annual value are all included. The program justifies its own budget every month.
95% confidence threshold enforced on every experiment
Most agencies call winners at 80% or when a stakeholder gets impatient. Redefine requires 95% confidence before any variant goes to full traffic. This prevents false wins that regress revenue after deployment.
Conversion rate optimization and user experience development in the same team
Separating experimentation strategy from implementation creates multi-week handoff delays. Redefine's conversion rate optimization strategists and Shopify developers work in the same sprint, so the time from hypothesis to live test is measured in days, not months.
Loser analysis included, not just winner celebration
Failed experiments generate the most useful learning. Redefine documents every loss with a root cause analysis that feeds back into the next hypothesis. Your backlog improves with every test cycle, winner or not.
Shopify A/B testing questions answered
A reliable split test requires at least 1,000 transactions on the page being tested per month. For checkout tests, that means 1,000 checkout initiations. For product detail page tests, 1,000 add-to-cart events. Stores below this threshold benefit more from Redefine's qualitative research and direct implementation approach, which uses session data, heatmaps, and user surveys to inform changes without formal splitting.
A test with adequate traffic typically reaches 95% confidence in 2 to 6 weeks depending on traffic volume and the size of the effect. Tests on high-traffic pages like homepages and product detail pages complete faster. Checkout tests take longer because they rely on completed purchases rather than page interactions. Redefine sets the minimum sample size and duration before any test launches so you know the expected timeline upfront.
Redefine works with Convert, VWO, Google Optimize where still appropriate, and Neat A/B for Shopify-native testing. The platform choice depends on your store's traffic volume, checkout complexity, and existing analytics stack. For Shopify Plus stores, Redefine uses checkout extensibility to run server-side checkout experiments without front-end performance impact.
Yes. Redefine runs experimentation programs on stores built by any agency or in-house team. The audit process evaluates your existing codebase, theme structure, and analytics setup before designing variants. No migration or rebuild is required to start testing.
A/B testing compares one variant against your control across your full traffic. Multivariate testing tests multiple elements simultaneously using factorial design to find the best combination. Multivariate tests require significantly more traffic to reach confidence, so Redefine recommends them only for pages with 10,000 or more monthly interactions. Most Shopify stores start with A/B tests and graduate to multivariate once the program matures.
