E-commerce website usability is whether a shopper can find the right product and pay for it without guessing. A new theme does not fix a catalog that hides the size, the shipping cost, or the difference between two similar items. The six fixes below are the ones that still move completed orders. Older posts on this site about mobile shopping, personalization gimmicks, and social add-ons now point here.
Site search should understand the name a customer uses, including the misspelling and the job the product does. Filters should match how people choose, such as size, compatibility, and price, not an internal SKU scheme. If search returns nothing, show the closest category instead of a dead end. Personalization is useful only after this works. Reordering the homepage for a stranger does less than returning the right product when they type.
Surprise shipping, a required account, and a coupon field that makes people leave to hunt for a code are still the reasons carts die. Show the shipping threshold early. Allow guest checkout. If you run promotions, apply the current one instead of daring people to find a code. Trust badges do not offset a total that jumped at the end.
Most retail sessions are on a phone. Thumb-sized fields, a keypad for phone and card numbers, address autocomplete, and wallets such as Apple Pay, Google Pay, or Shop Pay remove typing. Test the flow on a mid-range phone over a normal connection, not on the office wifi. A checkout that only works for your designer is not finished.
Oversized images and a pile of apps in the theme slow the page that is supposed to close the sale. Compress the photos, delay the chat widget until someone asks for it, and do not install an app for a feature you can do once in the theme. If the store is on a host that stalls at peak, the design work will not show up in the orders.
One or two emails to someone who added an item and did not buy is fair, if they can ignore the rest. Four texts is how you get marked as spam. The first note should link back to the same cart and answer the likely objection, usually shipping or fit. Measure recovered orders, not opens. The delivery rules are the same as any other mail you send. Authenticate the domain, or the recovery note never arrives. See email deliverability.
Watch ten session recordings of people who did not buy, or sit with a customer and stay quiet. The place they hesitate is the fix. Another homepage banner is probably not.
