Organise around the gap in the kitchen rather than around the manufacturer. Somebody who has measured a 595mm housing wants that number in the title; a page listing every oven you sell asks them to do the filtering you should have done.
Treat urgency as a category. A household without a working fridge is not comparing specifications — it's looking for the earliest possible delivery, and a shop that publishes the next available slot converts that search on the spot.
Write for the use, not the badge. "Quiet dishwasher for a flat", "washing machine for hard water", "oven for a family of five" are the questions people actually have, and the answers sell the appliance in the same paragraph.
Take repair enquiries seriously even when they end in a sale. Saying plainly when a fifteen-year-old machine isn't worth fixing earns the trust that decides where the replacement comes from, and it costs nothing to be honest about it.
