A redesign can improve appearance and still destroy the customer paths that were producing results. A site can look more polished after a redesign and perform worse at the same time. Those two outcomes aren’t in tension; they happen together more often than most businesses expect.

The situation I kept seeing

Earlier in my career, I watched a successful business bring in an outside agency to redesign a website that was already generating substantial revenue. The new site looked more polished, but the project changed URLs, altered the messaging, and disrupted the landing-page strategy that had been developed through years of testing.

Why the common response failed

Performance declined because the redesign treated the existing experience as something to replace rather than something to understand. Nobody asked which specific parts of the old site were actually earning the revenue before deciding what to change; the whole thing was treated as outdated by default.

What changed in my approach

That experience reinforced a lesson I have carried into every project since: preserve what the evidence says is working, identify the real constraints, and never confuse visual change with business improvement.

The practical lesson

A more polished design is not the same claim as a better-performing design. Before changing a page that’s already producing results, the first question is which specific elements the evidence says are actually working, so a redesign improves on those results instead of quietly erasing them.

Questions to ask about your own business

Before a redesign, do you know which specific pages, URLs, or messages are currently earning your results, or is the whole site being treated as due for a refresh?
Will the redesign change URLs or messaging that took years of testing to get right, and if so, is that change deliberate or incidental?
Is the goal of this redesign a better look, a better result, or an assumption that the two are the same thing?
