A website redesign can be a major investment in time, budget, and resources. Done well, it can improve usability, boost conversions, and better align your digital presence with your brand. Done poorly — without UX research — it can become an expensive exercise in guesswork.

The most expensive redesign is the one you have to fix twice.

The danger of assumption-led redesigns

Many redesign projects are driven by opinion, internal taste, or competitor envy. Teams change navigation because they “don’t like it” or overhaul layouts because “it feels outdated.” Without evidence, these changes risk making the experience worse for the people who actually use the site.

Skipping research means you might remove a feature users rely on, bury important content, or introduce new friction points. Even a visually stunning site can fail if it’s harder to navigate, slower to load, or less intuitive.

What UX research adds

UX research grounds redesign decisions in evidence. By combining usability testing, analytics review, and behavioural insight, you learn:

• Which elements users find valuable.
• Where friction or confusion occurs.
• How changes might affect key metrics like conversion or retention.

It also uncovers opportunities you might not have considered, for example, simplifying a form to reduce drop-off or adjusting microcopy to clarify next steps.

De-risking the process

Research before and during a redesign helps you:

• Prioritise changes that will have the biggest impact.
• Avoid breaking parts of the site that already work well.
• Test and refine ideas before full rollout.

This makes the launch smoother, reduces rework, and increases the chances of meeting your business objectives.

Evidence builds confidence

When design decisions are backed by user evidence, it’s easier to win stakeholder buy-in. It also helps set realistic expectations for timelines, budgets, and outcomes, reducing the risk of last-minute changes.
