Fix Shopify product page defects before testing
Do not A/B test a broken selector, incorrect price, missing label, slow script, or inaccessible control. Repair the defect and verify the fix.
Then choose a question that can change a buying decision. Fit guidance, delivery clarity, product evidence, and variant usability usually deserve attention before decorative preferences.
Build Shopify test ideas from evidence
Use support questions, returns, reviews, usability checks, page behavior, and Shopify sales reports. Separate observed problems from team preferences.
Write each idea as a shopper problem and proposed response. A useful hypothesis explains what changes, for whom, and which outcome will support the decision.
- Fix now: broken or misleading purchase behavior.
- Research next: an important problem with unclear evidence.
- Test first: one measurable response to an observed problem.
- Park: a preference without a shopper or business reason.

Choose the first A/B test manually
Compare a short list using evidence, decision value, traffic, effort, and risk. This is an educational review, not an automated backlog score.
Hypothetical example: shoppers repeatedly ask whether a jacket runs small. Test clearer fit guidance before changing the review card style.
Accessibility, legal, data, or brand risks can stop an idea regardless of its other strengths.
| Check | Prefer | Avoid |
|---|---|---|
| Evidence | Observed shopper difficulty | Internal preference |
| Decision value | A result that changes action | A curiosity metric |
| Traffic | Relevant eligible visits | Unrelated page traffic |
| Effort | One clear controlled change | Several bundled changes |
| Risk | Protected accessibility and trust | Known customer harm |
Run one clear Shopify product page test
Define the approved change, primary outcome, safety checks, and decision rule before exposure begins. Keep product facts and unrelated layout elements unchanged.
Check implementation on mobile and desktop. Watch errors, speed, orders, revenue, and returns alongside the primary outcome.

Use 100 Rocks for the approved comparison
The PDP Container renders approved variants. Behavior analytics also require the theme app embed and Analytics consent. Complete commerce funnel reporting requires the installed Web Pixel.
Tests use measurement-eligible PDP Container traffic within the chosen percentage. They cannot target a product, page, campaign, UTM, mobile-only group, or catalog subset.
Results and measured-session thresholds are separate by breakpoint. Each running test automatically promotes that breakpoint's highest observed KPI variant when its threshold is reached.
100 Rocks does not create or score a test backlog. This guide is educational, and your team chooses the question, approval, and final decision.
