From simple image swaps to advanced checkout flow optimization, ABSplitLab gives you every tool you need to understand what converts. All natively integrated with Shopify 2.0 themes, with zero performance impact.
Start running these tests immediately with the Free plan. No credit card required. These four test types cover the most common optimization needs for Shopify product pages.
Compare hero images side by side. Upload a new image or paste a URL, and ABSplitLab will show each variant to a random split of your visitors. Discover which product photo drives more add-to-carts and purchases. Works with all image formats including WebP and AVIF.
Test different product names and headings. Try short vs. long titles, benefit-driven vs. feature-driven copy, or emotional vs. rational phrasing. Small title changes can lift conversions by 10-20%. ABSplitLab makes it easy to test and measure the impact.
Test your Add-to-Cart button color. Green vs. orange? Black vs. blue? Stop debating and start measuring. ABSplitLab swaps the button color instantly with zero flicker. Enter any hex color code and see which CTA color gets the most clicks.
Test short vs. long product descriptions, different copy angles, or entirely different content structures. Does your audience prefer bullet points or paragraphs? Technical specs or emotional storytelling? Find out with data instead of guessing.
When you outgrow single-element testing, Starter plan unlocks page-level experiments. Test entirely different page structures and redirect visitors to alternative URLs.
Redirect a percentage of visitors to a completely different page URL. Perfect for testing a redesigned landing page, a new product page layout, or an alternative collection page. ABSplitLab handles the redirect before the page renders, so visitors never see a flash of the original page.
Test different Shopify page templates against each other. Does a long-form product page with embedded reviews outperform a minimal, image-focused layout? Template testing lets you compare structural differences without building a custom redirect system. Works with any Online Store 2.0 template.
Unlock price testing, checkout flow optimization, shipping message experiments, and the visual editor. These test types target the highest-impact conversion levers on your store.
Test different price points without changing your actual Shopify product price. ABSplitLab displays an alternative price to a segment of visitors while keeping the real checkout price unchanged. Measure price sensitivity, test psychological pricing ($29.99 vs. $30), and find your optimal price point before committing to a change.
Test different shipping copy on your product pages. "Free shipping over $50" vs. "Ships in 24 hours" vs. "Free express delivery." Shipping messaging is one of the most underrated conversion levers in ecommerce. ABSplitLab lets you test different shipping messages and measure which one drives more purchases and higher average order values.
Test the elements surrounding your Add-to-Cart button. Change the button text ("Add to Cart" vs. "Buy Now" vs. "Get Yours"), add urgency messages ("Only 3 left in stock!"), or test cart notice copy ("Free gift with purchase!"). These micro-copy changes happen at the highest-intent moment of the customer journey and can produce outsized conversion lifts.
Target any element on your page using a CSS selector and replace its content, style, or visibility. Test hero banners, announcement bars, trust badges, product badges ("Bestseller!"), section headings, or any other element. The visual editor gives you the power of a full CRO platform without writing code. Point, edit, test, and measure.
For stores that need custom code injection, international price testing, and AI-powered optimization. All the power of $500/month tools at a fraction of the cost.
Inject custom CSS and JavaScript for each variant. Perfect for developers and agencies who want full control over the test implementation. Test complex layout changes, add interactive elements, swap entire page sections, or inject third-party widgets. ABSplitLab handles variant assignment and statistical analysis while you control the code.
Test different prices for visitors in specific currency markets. Show $49.99 USD to US visitors while testing EUR 44.99 vs. EUR 39.99 for European visitors. Multi-currency price testing helps you optimize revenue across international markets. Works with Shopify Markets and any multi-currency setup.
Show a "Subscribe & Save" badge or subscription pricing offer to a segment of visitors. Test whether subscription offers increase conversions and average lifetime value. Works with popular subscription apps like Recharge, Bold Subscriptions, and Shopify native subscriptions. Measure the impact of subscription messaging before committing to a full rollout.
Other A/B testing tools slow down your store, cause visual flicker, and hurt your Google rankings. ABSplitLab was engineered from day one for speed. Your Lighthouse score stays perfect.
Visitors never see the original content before the variant loads. ABSplitLab uses the HTML hidden attribute to hide tested elements until variant assignment is complete. The swap happens in under 5 milliseconds, before the browser paints the first frame. Zero flicker, zero layout shift, zero CLS impact.
The entire ABSplitLab snippet is less than 2KB gzipped. For comparison, Google Analytics is 45KB and most A/B testing tools inject 50-200KB of JavaScript. Our snippet is smaller than a single product thumbnail image. It loads instantly and never blocks your page rendering.
Non-critical operations like event tracking use requestIdleCallback to execute only when the browser is idle. This means ABSplitLab never competes with your theme JavaScript, product images, or third-party apps for processing time. Your store stays fast even with multiple active experiments.
Variant assignment is stored in a first-party cookie (_splitlab_variant), not a third-party cookie or server-side session. This means assignment persists across visits, works with all browsers (including Safari ITP), and never gets blocked by ad blockers or privacy extensions. Your test data stays accurate.
ABSplitLab provides both frequentist and Bayesian statistical analysis. No statistics PhD required. We translate the math into plain-English recommendations.
Every experiment gets both a classical Z-test (p-value and confidence level) and Bayesian analysis (probability to beat control, credible intervals). The Free plan includes Z-test statistics. Growth and above unlock full Bayesian analysis with posterior distributions and expected loss calculations.
See the range of likely outcomes for each variant, not just a single point estimate. ABSplitLab calculates 95% confidence intervals for conversion rate, revenue per visitor, and average order value. Understand the uncertainty in your results before making decisions.
See the exact percentage improvement of each variant over the control. ABSplitLab calculates relative lift for all key metrics: conversion rate, add-to-cart rate, revenue per visitor, and average order value. Know exactly how much money you stand to gain by implementing the winning variant.
Before you start a test, ABSplitLab estimates how long it will take to reach statistical significance based on your current traffic levels. A real-time progress bar shows how close your test is to being conclusive. No more guessing when to stop a test.
Not all visitors are the same. ABSplitLab lets you target experiments to specific audience segments, so you can run personalized tests and get more actionable results.
Run tests exclusively for mobile, desktop, or tablet visitors. Mobile shoppers behave differently than desktop shoppers. Test a mobile-optimized hero image for phone users while showing the original to desktop visitors. Available on Growth plan and above.
Target experiments to first-time visitors or returning customers. New visitors might respond to trust signals and social proof, while returning customers might respond to loyalty offers and urgency. Test different messages for each segment.
Show different variants based on where the visitor came from. Test a specific headline for Google Ads traffic, a different one for Instagram visitors, and another for email campaigns. UTM parameter targeting lets you optimize landing pages for each traffic source.
Target tests by country, region, or city. Show localized pricing, shipping messages, or product descriptions to visitors from specific countries. Perfect for international stores that want to optimize for different markets. Available on Scale plan and above.
Leverage Shopify customer tags to target experiments. Show VIP pricing to tagged customers, test different offers for wholesale vs. retail buyers, or run exclusive experiments for loyalty program members. Available on Scale plan and above.
