One of the most important things for a brand is good web design. Web design can be the one thing that pushes you above or pulls you below your competition. Design matters, because it can reflect how you and your brand do business, and ultimately how your clients and potential customers see and feel about you.
This is particularly important when it comes to websites, which is essentially your online shop window. Make a bad impression, you lose a potential conversion. Make a good one, you gain a customer. Make a great impression, and you can potentially gain and keep a customer for life.
