Redesigns usually fail on the things nobody looked at
The classic redesign story: the new site looks great, launches on time, and a month later enquiries have quietly dropped. Usually it's because old pages that ranked well were deleted or moved without redirects, and the search traffic they carried went with them.
That's avoidable. We start with an inventory of what the current site is actually doing for you: the pages people land on, the queries they come from, the forms that get filled in. Those are the assets. Everything else is open for change.
