What is a CRO Audit?

An Ecommerce CRO Audit is a structured review evaluating a storefront across four primary pillars:

  1. Heuristic & Usability Review: Evaluating clarity, friction, distraction, and value proposition.
  2. Analytics & Funnel Review: Analyzing drop-off rates across devices and traffic sources.
  3. Technical Performance & Web Vitals: Auditing LCP, INP, CLS, and mobile responsiveness.
  4. Accessibility (WCAG): Verifying keyboard navigation, focus states, and contrast.

Audit Funnel Pillars

  • Homepage: Clear value proposition, fast search bar, navigation clarity.
  • PLP (Product Listing Page): Filtering speed, badge clarity, quick-add performance.
  • PDP (Product Detail Page): High-resolution media, prominent ATC button, trust signals, size guides.
  • Cart & Checkout: Sticky checkout buttons, transparent shipping costs, single-page checkout flow.

Developer Takeaway

Lighthouse Audit Automation: Automate Lighthouse CI performance and accessibility audits on pull requests to prevent regressions before code reaches production.
