The Ecommerce Conversion Rate Optimization Checklist.

A senior Shopify CRO team's audit framework — 9 pillars, ~50 checkpoints. Used internally by ConverX to diagnose 8 and 9-figure stores.

Most Shopify brands don't have a conversion problem. They have a prioritization problem. They run isolated tests, chase tactics from Twitter, and never compound. This checklist is the same one we walk every new ConverX partner through — built from auditing 194+ Shopify and Shopify Plus stores.

Work through it top-to-bottom. Any pillar where you can't honestly check 80% of the boxes is a sprint worth scoping.

1. Foundation & analytics

You cannot optimize what you cannot measure. Most Shopify stores lose 20–40% of trackable revenue to broken analytics before they ever ship a test.

  • GA4 enhanced ecommerce is firing view_item, add_to_cart, begin_checkout and purchase with consistent currency and ids.
  • Server-side tracking (Shopify Customer Events + Conversions API) is deployed for Meta and TikTok.
  • Consent mode is configured so EU/UK traffic is measured, not silently dropped.
  • A weekly funnel report exists: sessions → PDP → ATC → checkout → purchase, segmented by device and source.
  • You know your conversion rate by device. Mobile CR < 60% of desktop CR is a red flag worth a sprint.

2. Homepage & navigation

The homepage is the highest-traffic page on most Shopify stores. Treat it as a routing layer, not a brochure.

  • Above-the-fold hero communicates what you sell, who it's for, and the single best reason to buy within 3 seconds.
  • Primary CTA is a real product or collection link, not a vague 'Shop now'.
  • Top 3 bestsellers or hero collections are accessible in one tap from mobile.
  • Search is prominent and returns relevant results for at least your top 20 queries.
  • Social proof (reviews, press, UGC) appears above the fold or immediately below the hero.

3. Collection & category pages

Collection pages are where shoppers self-qualify. Friction here silently kills PDP traffic.

  • Filters match how customers actually shop (size, concern, use case) — not just internal taxonomy.
  • Product cards show price, review count, swatches and a clear primary image.
  • Out-of-stock items are demoted or hidden, never shown first.
  • Mobile sort and filter open a full-screen sheet, not a cramped dropdown.
  • First 8 products load in under 2.5s on mobile 4G.

4. Product detail page (PDP)

The PDP is where most CRO wins compound. A 10% PDP lift typically beats a 30% ad-cost reduction on revenue impact.

  • Hero image is high-resolution, lifestyle-led, and the gallery includes scale, ingredient/material, and packaging shots.
  • Title, price, reviews and add-to-cart are visible without scrolling on mobile.
  • Variant selection is unmistakable — no hidden swatches, no broken combinations.
  • Sticky add-to-cart appears on scroll for long PDPs.
  • Shipping, returns and guarantees are stated near the buy box, not buried in the footer.
  • Reviews are real, recent, and include photos. A 4.7+ average with 100+ reviews is the modern minimum.
  • FAQs answer the top 5 objections (sizing, ingredients, delivery, returns, comparisons).

5. Cart & upsell

The cart is your last chance to raise AOV without paying for another click.

  • Cart is a drawer, not a page redirect — keeps shoppers in flow.
  • Free-shipping threshold progress bar is visible and animated.
  • One relevant upsell or complementary product is shown — not five.
  • Trust badges (secure checkout, returns) appear inside the drawer.
  • Subtotal, discount and shipping estimate are clear before clicking checkout.

6. Checkout

Shopify's checkout converts best when you stop fighting it. Use Checkout Extensibility, not custom hacks.

  • Express payment options (Shop Pay, Apple Pay, Google Pay, PayPal) are above the form.
  • Guest checkout is enabled and not gated behind account creation.
  • Address autocomplete is on for every market you ship to.
  • Discount field is present but not the most prominent element — it is a leak when over-emphasized.
  • Post-purchase upsell (one tap, no re-auth) is configured for your top 1–2 add-ons.

7. Retention & lifecycle

CRO is not just first-purchase. Repeat-rate is the compounding lever — and the cheapest CAC you'll ever buy.

  • Welcome flow, browse abandonment, cart abandonment and checkout abandonment are all live in Klaviyo.
  • Post-purchase flow includes thank-you, education, review request and cross-sell — sequenced, not stacked.
  • Win-back flow targets customers 60/90/120 days post-purchase based on category cycle.
  • SMS is layered on top of email for time-sensitive moments (abandonment, launches, low stock).
  • Segmentation uses RFM or predicted CLV — not just 'engaged 30 days'.

8. Performance & technical

Every 100ms of mobile latency costs measurable conversion. Performance is a CRO lever, not a developer chore.

  • Lighthouse mobile performance ≥ 75 on PDP and collection pages.
  • LCP under 2.5s, CLS under 0.1, INP under 200ms on real Shopify traffic.
  • Theme apps audited quarterly — every app with < 5% adoption gets cut.
  • Images served as WebP/AVIF, properly sized for the rendered slot.
  • No render-blocking third-party scripts above the fold.

9. Experimentation cadence

CRO is a system, not a project. Stores that ship 2+ meaningful tests per month outperform stores that 'redesign' once a year.

  • A prioritized test backlog exists, scored by ICE or PXL.
  • Tests run for full business cycles (minimum 2 weeks), not until 'it looks good'.
  • Winning tests are documented with hypothesis, result and learning — not just shipped and forgotten.
  • Losing tests are documented too. They are the highest-value asset you own.
  • A monthly review aligns the team on what to test next quarter.
