Strategy
The case against redesigning everything
Full redesigns are expensive, slow, and frequently make things worse. When to refactor instead of rebuild.
A full redesign changes hundreds of variables at once. When conversion moves afterwards — up or down — you have learned nothing about why.
The hidden cost
Beyond the invoice: months without shipping, lost SEO equity on changed URLs, and a team that cannot iterate because everything is in flight at once.
When a redesign is genuinely right
Your positioning changed. Your audience changed. The underlying stack cannot support what you need. Those are real reasons. "It looks dated" usually is not.
The alternative
Sequence the work. Fix the highest-traffic page, measure, then move to the next. You ship value in week two instead of month five, and every change teaches you something.
