Shopify a/b testing & CRO tools after WooCommerce migration (2026)

After migrating from WooCommerce to Shopify, conversion rate optimization work restarts from a new baseline. The WooCommerce CRO stack (Google Optimize, Hotjar, custom PHP modifications) doesn't transfer directly — Shopify has its own testing landscape. Here's how to set up A/B testing and CRO on Shopify, including what changed after Google Optimize's sunset in 2023.

What changed after Google Optimize sunset (September 2023)

Google Optimize, the most widely used free A/B testing tool, was discontinued in September 2023. WooCommerce stores that relied on it need alternatives. Google has not released a direct replacement — this has driven migration to paid tools.

WooCommerce CRO stack (what you're replacing)

• Google Optimize: A/B testing on pages, product pages, checkout flow. Now sunset.
• Hotjar: Heatmaps, session recordings, surveys. Continues to work on Shopify.
• Microsoft Clarity: Free heatmaps and session recording (Google's competitor). Works on Shopify.
• VWO / Optimizely: Enterprise testing platforms. Continue to work on Shopify.
• WooCommerce Custom Checkout Fields: Test different checkout flows via custom PHP. Not possible in standard Shopify (Shopify Plus only).

Shopify A/B testing landscape

Heatmaps and session recording

Qualitative CRO research tools that work seamlessly on Shopify:

Hotjar

• Heatmaps: click, scroll, and move heatmaps on any Shopify page
• Session recordings: watch individual user sessions — see exactly where users hesitate, rage-click, or drop off
• Surveys: exit surveys on cart page, product pages
• Funnels: visualize drop-off across product → cart → checkout
• Pricing: free (35 sessions/day) to $99+/month. Install via Shopify app or script tag.

Microsoft Clarity (free)

Lucky Orange

• Combined session recording, heatmaps, live view, and conversion funnels
• Native Shopify integration with product view events
• Pricing: from $19/month

Post-migration CRO baseline reset

After migration, your CRO baselines are invalid — the new Shopify store may have a different conversion rate than WooCommerce due to platform differences (faster load time, Shop Pay, better mobile experience). Allow 4–8 weeks post-migration before starting new A/B tests:

1. Set new baseline: measure conversion rate, AOV, add-to-cart rate on Shopify for 30 days
2. Compare to WooCommerce historical baseline: has Shopify improved or decreased conversion?
3. Identify drop-off points: install Hotjar/Clarity and watch session recordings for the first 2 weeks
4. Prioritize tests based on highest-impact drop-off points, not based on WooCommerce test results

High-impact Shopify A/B tests post-migration

Product page tests

• CTA button color and copy: "Add to Cart" vs "Buy Now" vs "Get Yours"
• Product image ordering: lifestyle first vs product-only first
• Trust signals placement: reviews above/below fold, shipping and returns near CTA
• Price display: showing compare-at (was) price vs current price only
• Description format: long paragraph vs bullet points vs accordion tabs

Cart and checkout tests

• Free shipping threshold: $50 vs $75 vs $100 — use Intelligems for this test
• Cart upsell timing: show upsell before checkout vs after add-to-cart
• Checkout trust badges: show badge placement above/below "Complete order" button

Homepage and collection tests

• Hero CTA copy and destination: collection page vs bestseller product
• Product grid density: 2-column vs 3-column on mobile
• Product card elements: show price, reviews, and quick-add vs minimal cards

Shopify native CRO features

Built-in Shopify features that often lift conversion without testing:

• Shop Pay: Pre-filled checkout for returning Shopify customers. Typically lifts conversion 5–15% vs non-Shop Pay checkout.
• Buy Now Pay Later (Shop Pay Installments, Klarna): Showing monthly payment on product pages increases conversion on high-ticket items.
• Sticky add-to-cart: Some themes include a sticky ATC bar on product pages — test this if your current theme doesn't have it.
• Countdown timers: For urgency on promotions — Hextom Banner app for time-limited offers.

CRO migration checklist

• Install Microsoft Clarity (free) immediately — start collecting session data from day 1
• Set up GA4 funnel report: product view → add to cart → checkout → purchase
• Establish 30-day post-migration baseline before starting A/B tests
• Compare Shopify baseline to WooCommerce historical conversion rate
• Watch session recordings for first 2 weeks — identify obvious friction points
• Identify top 3 A/B test candidates based on session recordings and funnel data
• Select A/B testing tool: Intelligems (price/shipping), Shogun/GemPages (page layout), VWO (enterprise)
• Set up first test: start with highest-impact, simplest change
• Run test to statistical significance (minimum 100 conversions per variant)
• Don't run more than 2–3 tests simultaneously — maintain clean data

The biggest post-migration CRO mistake is using WooCommerce A/B test results to make Shopify changes. The two platforms are different enough that WooCommerce learnings are hypotheses on Shopify, not proven facts — they're good starting points for test prioritization, but they need to be validated with Shopify-specific data. Start fresh with session recordings and baseline measurement, then test systematically.
