Redesign the constraint
A redesign should start when the current site blocks trust, speed, clarity or measurement. If the problem is only visual fatigue, you risk spending money without changing the sales conversation.
Keep what converts
Do not throw away pages, proof, rankings or user habits before reading the data. A premium rebuild preserves useful demand and removes the parts that create hesitation.
Launch with instrumentation
The new site should ship with events for qualified leads, form progress, booking intent, product interest and source quality. Without instrumentation, a redesign becomes a taste argument again.
