How to redesign an existing website?

Passionate Designer & Founder
Redesigning an existing website breaks into six sequential phases: strategy audit, positioning clarity, sitemap and content architecture, visual design, build, and launch. Skipping phase one is the single most expensive mistake founders make. You end up with a site that looks newer but converts at the same rate as the old one, because the root problem was never the design — it was positioning. Fixing fonts doesn't fix that.

Start with what you have. Pull three months of session data and find the three pages with the highest exit rate. Exit rate tells you where the story breaks down, not where the design looks bad. For most B2B SaaS sites we audit, the problem is in the hero and the pricing page, two pages that carry 70-80% of conversion weight but are often written by committee and designed last, after everyone has already argued themselves into exhaustion.
The six phases, in order
Phase one is a strategy audit: document who the site is for, what decision you are helping them make, and why they should choose you. If your leadership team gives three different answers to those questions, no redesign will fix your conversion rate. Phase two is positioning clarity, typically a 2-4 week engagement that produces a brief every downstream deliverable is written against. See our work on brand positioning for how that runs in practice.
Phase three is sitemap and content architecture. Most sites we inherit have 40+ pages, 12 of which get 90% of traffic. The other 28 split crawl budget and confuse visitors. Cut aggressively. Phase four is visual design: wireframes first, then high-fidelity mockups in Figma, then a design system that locks spacing, typography, and component behavior. A design system built during the redesign pays off for 18-24 months of future updates without anyone arguing about button radius again.
Phase five is build. Webflow handles 80% of marketing site requirements for growth-stage companies without requiring a developer on retainer. For product-adjacent pages or complex gating logic, budget 3-5 weeks for a clean Webflow build, or 8-14 weeks for a custom-coded site. Phase six is launch, and launch does not mean go-live. It means QA across six browsers, three device breakpoints, and a full redirect map for every URL that changes. Missing that last step causes immediate SEO loss, and most agencies skip it because it's tedious and unsexy.
On a Series-B fintech we worked with last year, the opening audit revealed their site was targeting procurement managers but 73% of inbound leads came from CTOs. The redesign was built around that audience flip. Demo-request conversion went up 38% within 60 days of launch. That result came from the audit, not the Figma file.
A redesign that starts in Figma before the positioning brief exists is an expensive visual refresh. It makes the team feel productive without changing anything that matters.
