A lot of people still judge a book by its cover and for any given company, the homepage is its virtual front door. If a new visitor doesn't like what he/she sees, the reaction is to hit the "back" button.
Your website is a crucial marketing tool. People no longer look you up in the phone book, but ‘Google’ you and expect to find a company’s website with a strong online presence.
To consider design effectively, you need to realise that design is much more than merely a colour palette and a set of typefaces.
Design work can add value and credibility to your project, product or service and not forget, make it more understandable.
Without a design it's just an idea and you cannot market ideas. It doesn’t have to be overly expensive, sophisticated or large, but you do need a well designed, professional looking, easy to navigate online presence for your business to be seen as both professional and credible.
