Why a redesign is riskier than a new build
A new site starts at zero and can only go up. A redesign starts with something that already works to some degree, and the most common outcome of doing it badly is a site that looks far better and gets fewer enquiries. The reasons are almost never visual: URLs change without redirects, pages that quietly ranked get deleted because nobody checked, copy gets shortened for balance and loses the terms it ranked for. None of that applies to a first build, which is why the process here starts with an audit rather than a design.
