Cost is searched before anything else. Ranges by size and specification, with what changes the figure, is the page people read repeatedly, and refusing to publish numbers sends them to a competitor who will.
Duration is the second question and nobody answers it. Publishing how many working days a typical fit takes, and what delays it, wins trust from somebody who has heard horror stories from a neighbour.
Style browsing starts early. Searches for a look — handleless, shaker, a colour, an island — happen months ahead of a decision, and being present then means being on the shortlist when the money is ready.
Some people already bought the kitchen. Searching for a fitter to install a flat-pack purchase is a distinct, frequent query, and companies that will take that work should say so instead of leaving the visitor guessing.
