Ecommerce CRO Checklist
A walk-through audit of every key conversion surface in your store — homepage, PDP, PLP, cart, checkout, thank-you — used to find obvious wins before you spin up experiments.
Ecommerce CRO Checklist
A surface-by-surface audit of an online store's conversion funnel used to surface obvious fixes before designing A/B tests.
An ecommerce CRO checklist is a structured walk-through of the pages that decide whether a visitor becomes a buyer: homepage, category (PLP), product (PDP), cart, checkout, and the post-purchase thank-you page. Each surface gets a short list of heuristic checks — value proposition clarity, trust signals, mobile layout, friction in form fields, page speed — that you score pass/fail in one pass.
The goal is not to run experiments yet. It's to find the changes a reasonable person would call broken or obviously suboptimal, ship those first, and reserve test capacity for genuinely uncertain decisions. Most stores find 10-20 quick wins in a first-pass audit.
A checklist works because most conversion problems aren't subtle. Before you spend two weeks designing a test of headline variants, it's worth checking whether the PDP loads in under three seconds on a mid-range Android, whether shipping cost shows before checkout, and whether the cart button is visible without scrolling. These aren't hypotheses — they're hygiene.
Use this checklist as the first step of any ecommerce CRO programme. Run it on your top three traffic landing pages and your full purchase flow. Anything that fails a check goes into one of two buckets: ship-it-now (obvious fixes, low risk) or test-it (when the fix involves a real trade-off, like removing a coupon field that converts non-coupon users but kills coupon users).
Audit before you experiment
A/B testing a broken page is expensive — you spend traffic learning what a five-minute audit would have told you for free. Run the checklist first, ship the unambiguous fixes, then test the genuine trade-offs. This is also why we recommend importing historical GA4 data on day one: a 12-month behavioural baseline makes the audit findings concrete, not theoretical.
The checklist, surface by surface
Homepage. Within five seconds a first-time visitor should know what you sell, who it's for, and why they should care. Check: a specific value proposition above the fold (not 'Welcome to our store'); a hero image of the actual product, not a lifestyle abstraction; clear primary navigation by category; trust signals — reviews count, press logos, or a recognisable guarantee — visible without scrolling; a search bar on mobile; and a fold that doesn't disappear under a cookie banner.
Category page (PLP). The PLP is where browsers self-select. Check: product cards show price, a star rating, and a key attribute (colour swatch, size availability); filters match how shoppers actually think (price, size, in-stock — not internal SKU taxonomy); sort defaults to something useful (best-sellers, not 'featured'); pagination or infinite scroll loads in under a second; out-of-stock variants are dimmed, not hidden; and the mobile grid is two columns, not one.
Product page (PDP). This is where intent crystallises. Check: a gallery of 5+ images including scale shots and a video or 360 view; price, stock status, and delivery date visible without scrolling on mobile; size guide one tap away; reviews with photos, not just star averages; clear returns policy near the buy button; an add-to-cart button that doesn't move when you tap variants; and bundle or cross-sell modules that load after the buy button is interactive, not before.
Cart, checkout, thank-you. Cart: shipping cost and delivery date shown before the user clicks checkout, no surprise fees later. Checkout: guest checkout offered first, address autocomplete enabled, payment methods that match the market (iDEAL in NL, Klarna in DE, Apple Pay everywhere). The coupon field is the single biggest leak — if you don't run promotions, remove it. Thank-you page: order confirmation with a delivery estimate, a referral or review prompt, and one cross-sell — not five.
Frequently asked questions
A full audit every quarter, plus a focused re-check after any major release (new theme, new checkout, new payment provider). Most stores also keep a lightweight monthly version that just spot-checks page speed, mobile layout, and checkout completion.
No — fix the unambiguous things (broken images, slow PDP, hidden shipping cost) without testing. Reserve A/B tests for changes that involve a real trade-off, like rewriting your value proposition or restructuring your PDP layout. Testing obvious fixes wastes traffic.
It's the diagnostic step of an ecommerce CRO programme. CRO as a discipline cycles through audit → hypothesis → test → ship → measure. The checklist powers the audit phase and feeds the hypothesis backlog for the testing phase.
The audit itself is just inspection — it doesn't add scripts. What you want to watch is the cumulative weight of the analytics, heatmap, and A/B testing tools you've already installed. Consolidating those into one lightweight snippet typically claws back 200-600ms of LCP on a mid-range Android.
Hidden shipping cost in the cart, almost every time. Stores that move shipping cost and delivery date into the cart summary (or earlier) typically see cart-to-checkout completion lift 5-15%. It's a near-universal fix.
Partially. Page speed, broken links, missing alt text, and form-field errors can be automated. Judgement calls — does the value proposition actually resonate, is the hero image right for this audience — still need a human review. AI-assisted audits can flag candidate issues, but a person decides what to ship.
For a single-store catalogue of under 500 SKUs, plan on 4-6 hours for the audit itself plus another 2-3 hours to triage findings into ship-now vs test-it. Larger catalogues or multi-market stores (Shopify Markets, multiple currencies) can stretch this to a full day.
Mobile, always. For most apparel, beauty, and consumer goods stores, 70-85% of sessions are mobile and 55-70% of revenue is mobile. Desktop is the secondary surface — audit it second and treat any conflicts (e.g. mobile-optimised hero looks weak on desktop) as a separate problem.
Three filters: reversibility (can I roll it back in five minutes?), traffic risk (does it touch the buy button?), and brand risk (does it change how the store reads). If all three are low, ship it. If any one is medium-high, A/B test it. Headline rewrites usually test; alt-text fixes usually ship.
Yes — the surfaces (homepage, PLP, PDP, cart, checkout) and the heuristics are platform-agnostic. The implementation details differ: WooCommerce gives you more theme-level control, Magento has heavier built-in checkout flows. The diagnostic questions are the same.
