Ecommerce website problems should be judged by their effect on product discovery, purchase confidence and completed orders — not by generic design rules.
High-impact ecommerce mistakes
- Weak category navigation: customers cannot narrow a large catalogue efficiently.
- Thin product pages: missing specifications, sizing, imagery, delivery information or meaningful differentiation.
- Late surprises: delivery costs, returns or restrictions appear too late in the journey.
- Poor mobile buying UX: variants, filters, cart or checkout become awkward on smaller screens.
- Stale stock data: availability and merchandising do not reflect what can actually be purchased.
- Trust buried at checkout: payment, returns, reviews and service reassurance appear after the buying decision.
- Broken measurement: purchases, refunds and customer type are not tracked reliably.
