Look for variety across industries, evidence of strategic thinking (not just visuals), and — ideally — performance data showing the work actually drove results. A polished portfolio proves design skill, but not business impact. Ask directly for case studies with numbers: traffic growth, conversion lift, load speed improvements. Agencies confident in their results will have this ready; agencies that only show screenshots usually don't track outcomes closely.

Your website needs a redesign if it's not mobile-responsive, loads slowly, uses an outdated or unsupported CMS, or no longer reflects your current brand and offering. Declining conversion rates, rising bounce rates, or a site your own team is embarrassed to share are strong signals too. If updating content requires a developer every time, that's a structural problem a redesign should fix — not something to keep working around.

A web designer plans and creates the visual layout, user experience, and structure of a website — translating business goals and brand identity into pages that are both usable and persuasive. Good web design goes beyond aesthetics: it includes information architecture (how content is organized), UX flow (how visitors move through the site), and conversion design (how pages guide action). The best designers think like strategists first, decorators second.

Optimize if your site's foundation is solid but underperforming in specific areas; redesign if the structure, messaging, or technical foundation is fundamentally holding the business back. A full redesign makes sense when incremental fixes keep hitting a ceiling — outdated CMS, poor mobile experience, or messaging that no longer matches your business. If the core is sound, targeted CRO and content improvements are faster and cheaper than starting over.

Start by auditing your messaging clarity, your calls-to-action, and your checkout or lead-capture flow — most non-converting sites have friction in one of these three areas. Use analytics to find where visitors actually drop off before assuming what's broken. Sometimes it's traffic quality, not the site itself. But if visitors are landing on the right pages and still not converting, the fix is almost always clarity and friction — not a full redesign.

Average website conversion rates fall between 2% and 5%, though this varies significantly by industry — e-commerce tends to run lower, B2B lead-gen sites often run higher. Benchmark against your own historical data more than industry averages, since traffic quality and offer type vary a lot. The more useful question is: what's your current rate, and what would a 1-point improvement be worth in revenue? That reframes CRO as a growth lever, not a vanity metric.
