A Systematic eCommerce Audit Checklist That Actually Works
Most eCommerce audit checklists give you 10 vague tips and call it a day. "Improve your product pages." "Make your site faster." That's not a checklist. That's a wish list.
This is the exact 277-point framework we built into AuditYourStore's AI engine, organized into 7 categories that cover every surface where your store gains or loses conversions. Each checkpoint tells you what good looks like, what bad looks like, and why it matters with research to back it up.

Category 1: Product Pages
Your product pages are where buying decisions happen. Baymard Institute research shows that 10% of the top-grossing US eCommerce sites have product page UX rated "poor" or "mediocre." Here's what to check.
Image Quality and Quantity
Good: 5+ high-resolution images per product showing multiple angles, scale reference, and lifestyle context. WebP format with zoom support.
Bad: 1-2 low-res images, no lifestyle shots, no zoom. Images blurry on mobile.
Why: Products with multiple images convert up to 58% better than single-image listings.
Description Depth
Good: Benefit-led descriptions with scannable formatting, 150+ words, addressing common objections and including specifications.
Bad: One-sentence descriptions, manufacturer copy-paste, walls of unformatted text.
Why: NNGroup research shows 20% of purchase failures stem from incomplete product information.
Social Proof and Reviews
Good: Star ratings near the product title, customer photos, verified purchase badges, review count displayed prominently.
Bad: No reviews visible, reviews hidden behind a tab, fake-looking reviews with identical language.
Why: Products with 5+ reviews convert 270% better than those with none.
Price Clarity
Good: Price immediately visible, compare-at pricing shows savings, shipping cost stated on the product page.
Bad: Price hard to find, shipping costs only revealed at checkout, confusing pricing tiers.
Why: 48% of cart abandonment is caused by extra costs revealed at checkout (Baymard Institute).
Add-to-Cart Visibility
Good: High-contrast button above the fold, sticky on mobile, visual confirmation when item is added.
Bad: Button below the fold on mobile, low contrast, small tap target, no feedback after clicking.
Why: Sticky add-to-cart buttons increase mobile conversions by 8% or more.
Category 2: Checkout Flow
Baymard Institute's research across 49 studies puts average cart abandonment at 69.8%. Your checkout is where the most revenue evaporates.
Guest Checkout
Good: Purchase without account creation. Account creation offered after purchase, not before.
Bad: Mandatory registration with 8+ fields before checkout. Guest option hidden behind a small text link.
Why: 24% of shoppers abandon specifically because they're forced to create an account.
Form Field Count
Good: 7-8 fields maximum. Auto-fill supported. Address lookup auto-completes from zip code.
Bad: 15+ fields, separate billing/shipping by default, no auto-fill, unclear labels.
Why: The average US checkout has 14.88 fields (Baymard), nearly twice the optimal number.
Payment Methods
Good: Credit cards, PayPal, Shop Pay, Apple Pay, Google Pay, and Buy Now Pay Later options visible.
Bad: Credit card only, no digital wallets, payment icons not visible until the payment step.
Why: 13% abandon due to insufficient payment methods. Shop Pay converts at 1.91x the standard rate.
Order Summary Visibility
Good: Persistent summary showing product thumbnail, name, quantity, shipping, tax, and total throughout checkout.
Bad: Summary hidden behind a toggle on mobile, no thumbnails, total only visible on the last step.
Why: Shoppers who can't see what they're buying feel uncertain. Uncertainty kills conversions.
Error Handling
Good: Inline validation as fields are completed. Specific error messages next to the relevant field.
Bad: Errors shown only after submission, vague messages at the top of the page, form data cleared on error.
Why: Confusing errors cause 18% of shoppers to abandon. Inline validation reduces errors by up to 22%.
Category 3: Trust and Security
97% of consumers express concern about online shopping security (Baymard Institute). If visitors don't trust your store, nothing else matters.
SSL and Security Indicators
Good: Valid SSL with no mixed content warnings, HTTPS on all pages, security badges near checkout areas.
Bad: HTTP pages, mixed content warnings, "Not Secure" browser alerts.
Why: 84% of shoppers would abandon a purchase on a site without HTTPS.
Return Policy
Good: Clear policy linked from product pages, footer, and checkout. Plain language stating return window and refund process.
Bad: No visible policy, buried in the footer only, dense legal jargon, vague terms.
Why: 67% of shoppers check the return policy before buying. A visible policy increases conversions up to 17%.
Contact Information
Good: Contact page with email, phone or chat, and physical address. Link visible on every page.
Bad: No contact page, form-only with no email, no phone number, more than two clicks to find.
Why: NNGroup identifies hiding contact information as a top credibility-killing pattern for eCommerce.
Payment Security Badges
Good: Recognizable payment logos near the add-to-cart button and in the checkout footer.
Bad: No badges, or badges in the footer only, outdated or low-resolution graphics.
Why: Trust badges near the checkout button increase conversions by up to 42% in split tests.
About Us Page
Good: Real founder photos, brand story, team info, social links. Authentic and human.
Bad: Stock photos, boilerplate text, no real people, no mission or story.
Why: The About page is top-5 most visited on eCommerce sites. It's where skeptical shoppers decide if you're real.
Category 4: Mobile UX
Mobile drives 70%+ of eCommerce traffic, yet mobile converts at just 1.2% versus 1.9% on desktop. Most of that gap is fixable UX, not "people just browsing."
Tap Target Size
Good: All buttons, links, and form fields at least 44x44 pixels with adequate spacing.
Bad: Small links crammed together, tiny buttons requiring precise tapping, accidental mis-taps.
Why: Google recommends 48x48 CSS pixels minimum. Undersized targets are the top mobile usability issue.
Text Readability
Good: Body text at 16px minimum, line height 1.4+, contrast ratio 4.5:1, no horizontal scrolling.
Bad: Font below 14px, low-contrast text, content cut off at edges, pinch-zoom required.
Why: Readability issues increase mobile bounce rates by up to 113% (Google mobile usability research).
Mobile Navigation
Good: Easy-to-find hamburger menu, clear hierarchy, prominent search, sticky header with cart icon.
Bad: 3+ taps to reach any product, tiny menu icon, no search, mega-menus broken on touch.
Why: Poor navigation is the second most common reason for mobile shopping abandonment (NNGroup).
Mobile Forms
Good: Correct keyboard types (numeric for phone, email for email), persistent labels, large fields.
Bad: Text keyboard for all fields, placeholder-only labels, fields too small to type in.
Why: Mobile form completion rates are 50% lower than desktop. Every improvement directly lifts checkout completion.
Responsive Layout
Good: Content reflows properly, images resize, no horizontal scroll, critical content visible without excessive scrolling.
Bad: Desktop layout squeezed onto mobile, images overflowing, add-to-cart pushed far below the fold.
Why: Responsive design is about prioritizing the right content for mobile shoppers with smaller viewports and less patience.
Category 5: Page Speed
Google's research across 11 million mobile pages found that going from 1 to 5 seconds load time increases bounce probability by 90%. Speed is a conversion multiplier.
Largest Contentful Paint (LCP)
Good: Under 2.5 seconds. Hero and product images properly sized in WebP or AVIF format.
Bad: Over 4 seconds, unoptimized hero images, visible loading spinners, PNG or uncompressed JPEG.
Why: LCP is a Core Web Vital that directly affects search rankings. Pages under 2.5s have 22% lower bounce rates.
Cumulative Layout Shift (CLS)
Good: Score under 0.1. Images have defined dimensions. Fonts load without text jumps.
Bad: Score over 0.25. Content shifts as elements load. Banners push content down after render.
Why: When a shopper tries to tap "Add to Cart" and the button jumps, that's a lost sale and a customer who won't return.
Total Page Weight
Good: Under 3MB. Images compressed and properly sized. CSS and JS minified.
Bad: Over 8MB, 4000px images displayed at 800px, unminified files, unused app scripts on every page.
Why: An 8MB page on a 3G connection takes 20+ seconds to load.
Third-Party Scripts
Good: Essential scripts only, loaded async or deferred. Total third-party payload under 500KB.
Bad: 15+ scripts on every page, abandoned app scripts still firing, chat widgets loading immediately.
Why: Each Shopify app adds 50-500KB of JavaScript. Ten apps can mean 2MB of extra scripts per page view.
Image Optimization
Good: WebP/AVIF format, properly sized for display dimensions, lazy-loaded below the fold, CDN-served.
Bad: 2MB+ PNG product photos, 4000x4000 images in 400x400 containers, no lazy loading.
Why: Images account for 50-80% of page weight. Optimizing them alone can cut load times by 40-60%.
Category 6: Navigation
If shoppers can't find products within 3-4 clicks, they leave. Navigation directly impacts product discovery and whether visitors ever reach a page where they can convert.
Category Structure
Good: Logical hierarchy matching how shoppers think. Max 7 top-level categories. Clear, non-overlapping subcategories.
Bad: 15+ top-level categories, overlapping names, categories organized by brand when customers think by product type.
Why: 27% of eCommerce sites have category structures causing navigational dead-ends (Baymard Institute).
Search Functionality
Good: Prominent search bar on all pages, handles typos and synonyms, results show images and prices.
Bad: Search hidden behind an icon, zero results for misspellings, dead-end "no results" pages.
Why: Shoppers who use search convert at 1.8x the rate of browsers. But 61% of search implementations fail on synonyms.
Breadcrumbs
Good: On all product and category pages, showing the full path, clickable, present on mobile.
Bad: Missing on product pages, showing only "Home > Product Name" without category, non-clickable.
Why: Breadcrumbs reduce bounce rates and improve SEO through internal linking structure.
Filtering and Sorting
Good: Relevant filters (size, color, price, rating), option counts shown, no page reload required.
Bad: No filters on collections, zero-result options shown, filters reset on back navigation.
Why: 42% of eCommerce filtering implementations have major usability issues (Baymard Institute).
Footer Navigation
Good: Links to policies, contact info, social media, popular categories, and trust signals. Organized in clear groups.
Bad: Empty footer, copyright notice only, missing policies, broken links.
Why: The footer is where shoppers go for trust-building information before committing to a purchase.
Category 7: Email Capture
98 out of 100 visitors leave without buying. Email capture gives you a second chance. Returning visitors convert at 4-5x the rate of first-time visitors.
Popup Timing
Good: Appears after 15-30 seconds or on exit intent. Easy to dismiss. Doesn't re-appear every page. Suppressed for existing subscribers.
Bad: Fires instantly on load, hard to close, appears on every page view, covers entire mobile screen.
Why: Aggressive popups increase bounce rates by 40%. Google penalizes intrusive mobile interstitials.
Value Proposition
Good: Specific incentive: 10% off first order, free shipping, exclusive access. Benefit prominently featured.
Bad: "Subscribe to our newsletter" with no incentive. Vague "stay updated" promises.
Why: Discount popups convert at 7-10% versus 1-2% for generic newsletter prompts. That's a 5x difference.
Form Simplicity
Good: Email field only (or email + first name). Single click to submit. Clear privacy note.
Bad: Requesting email, name, phone, birthday, and preferences. Multiple steps.
Why: Each additional field reduces conversion by approximately 11%. Collect more data later through progressive profiling.
Mobile Email Capture
Good: Properly sized for mobile (not 100% viewport), tappable dismiss button, large input fields.
Bad: Desktop popup rendered on mobile, tiny X button, fields requiring zoom.
Why: Google's interstitial penalty specifically targets mobile popups covering main content.
Embedded Alternatives
Good: Email forms in the footer, blog posts, and floating bars in addition to popups.
Bad: Relying solely on a popup. No signup option visible after the popup is closed.
Why: 70% of visitors who close a popup never see it again. Embedded forms add 20-30% more signups.
Your Audit Action Plan
You've just evaluated your store across 35 critical dimensions spanning 7 categories. Here's how to prioritize fixes:
- Trust and security first. Missing SSL, no return policy, no contact info are conversion killers affecting every visitor. Quick fixes, outsized impact.
- Checkout friction next. At 69.8% average abandonment, even small checkout improvements yield significant revenue. Guest checkout and fewer form fields are high-impact, low-effort.
- Page speed. Compress images, remove unused scripts. Each second saved recovers roughly 7% of lost conversions.
- Product pages. More images, deeper descriptions, reviews. These compound as every product page improves.
- Mobile UX. With 70%+ mobile traffic, mobile fixes have the widest reach.
- Navigation. Better search and filtering means more products discovered, more chances to convert.
- Email capture. Your long-term engine. Most visitors won't buy on the first visit. Email brings them back.
