A useful audit begins with the store’s audience, offer and traffic mix. The same pattern can help one category and distract another, so generic lists of best practices need context.
Review the journey in layers: measurement reliability, mobile usability, navigation, collection discovery, product decision support, trust, cart friction, performance and accessibility.
Finish with a prioritised roadmap. Each recommendation should state the observed issue, why it matters, the proposed change, effort and how the team will know whether it helped.
Choose one high-value journey, document the current evidence and give the next change an owner, a success signal and a review date.
