Start with what has changed.
Perhaps your company has grown into new services. Perhaps the team, equipment or geography has changed. Your website may still describe the business you used to be.
The first question is not which colour or font to choose. It is what a potential customer needs to understand about the company today. That answer gives the design a purpose.
Find the story inside the business.
A company can have considerable expertise and still struggle to explain what makes it a good choice. Too often, its website puts a long list of services in front of the reader without showing how they connect.
A redesign can bring that story into focus: what you do particularly well, who it is for and what the next step looks like. The language should sound like people who know their work.
Give every part the same standard.
The website is usually one piece of a larger introduction. A company profile, a sales presentation or a brochure might follow it into the next conversation.
When those materials tell different stories or look unrelated, they create unnecessary friction. A considered brand package brings them together around the same language, typography and visual identity.
Judge the result by its usefulness.
Look beyond the opening image. Can someone find the right service, understand your coverage and get in touch? Does the mobile version feel as considered as the desktop? Are the important facts current?
The finished website should feel like your business at its best. More than a fresh coat of paint, it should be a clearer, more useful introduction.
