When having a website created there needs to be a lot of thought in to how it will function but also the appearance. Too often websites seem to have covered one aspect but not the other. Your website should very much match your company ethos and portray what your company offers. If for example you are a dentist surgery you would want to make your website clean and professional as this will then make your visitors feel that your establishment is clean and professional, which is what people are looking for in this type of industry.
If you are in some sort of design or art industry, you may want to consider something a little more quirky and colourful to show off your creative side. Whatever you chose, make sure that you are happy that the final designs match the image you want to portray as often a website is the first impression a client or customer will make of your business.
