How We Audit a Shopify Store: Our Exact CRO Process

A Shopify CRO audit has one purpose: identify where and why visitors leave without buying, ranked by revenue impact. It takes 5-7 days to do properly. This is our exact process — every step, every tool, and every question we are trying to answer. You can run most of this yourself; the value of having it done professionally is pattern recognition and implementation speed.

Phase 1: Analytics Foundation (Day 1)

Before looking at the store, we look at the data. The questions we are answering: where does traffic come from? Which pages do visitors enter and exit on? Where does the funnel leak?

Phase 2: Performance Audit (Day 1-2)

Speed is often the highest-ROI fix available — and it is measurable before any other work begins. We run PageSpeed Insights on the home page, top three product pages, and checkout. Mobile score below 45 is a priority fix before any CRO work begins — you cannot optimise a conversion funnel that is too slow to load.

We also check Core Web Vitals in Google Search Console: LCP (Largest Contentful Paint) should be under 2.5 seconds on mobile. CLS (Cumulative Layout Shift) should be under 0.1. INP (Interaction to Next Paint) under 200ms. Failures in any of these directly suppress conversion rate and search rankings simultaneously.

Phase 3: Session Recording Analysis (Day 2-3)

We watch 50-100 session recordings in Microsoft Clarity, filtered to sessions that reached the product page but did not purchase. We are looking for:

• →Rage clicks — where do frustrated users click repeatedly?
• →Scroll depth — how far down the product page do users actually read?
• →Hesitation points — where do users pause before exiting?
• →Dead elements — buttons or links users click that do not respond correctly
• →Mobile-specific issues — elements that are technically present but functionally unusable on a small screen

Phase 4: Heuristic UX Review (Day 3-4)

A structured evaluation of the store against conversion best practices. We review every page in the purchase funnel against a 47-point checklist covering:

Phase 5: Qualitative Research (Day 4-5)

Data tells us what is happening. Customers tell us why. We review support tickets and chat transcripts from the past 90 days looking for recurring friction themes — questions about sizing, shipping, returns, ingredients, or product suitability that indicate information gaps on the store.

For brands with sufficient email volume, a post-abandonment survey ("What stopped you from completing your purchase?") with four answer options provides quantitative prioritisation of the qualitative causes.

Phase 6: Prioritised Recommendations (Day 5-7)

All findings are scored using the PIE framework: Potential impact, Importance (traffic volume of affected pages), and Ease of implementation. Each recommendation gets a PIE score, a revenue impact estimate, and an implementation complexity rating.

The output: a prioritised action list where the top five items represent the highest revenue-per-week-of-implementation ratio. These become the first 90-day test roadmap.

This is exactly what is delivered in a GrowWithCRO audit. The free version covers Phase 1-3 for your highest-traffic product pages and gives you the three highest-impact quick wins. The full audit covers all six phases and forms the foundation of an ongoing CRO programme.
