Your website is the hub of your online business; it is the living representation of your company whether your company exists physically or not. When you are doing business online, people cannot see you physically like how they could if they were managing with an offline company. Hence, individuals do judge you by your covers. This is where a great design comes in.
Think if you are working an offline company. Would you allow your salespersons to be dressed in shabby or casual garments when they are dealing with your customers? By getting your staff wear professionally, you are telling your customers that you do worry about quality. This works merely because first impressions matter.
Similarly, the same example is with your website. If your website is position together shabbily and looks like a 5 minute “quick fix”, you are literally screaming to your visitants that you are not professional and you do not worry for quality.
On the opposite, if you have a completely professional looking website layout, you are making your visitors the perception that you have made particular attention to each detail and you care about professionalism. You are organised, focused and you really mean business.
On the other hand, you should also have anything related to your company well designed. From business cards to letterheads to promotional brochures, every little bit matters. This is because as you grow your business, these details become the face of your business. Once again, think of the “salesperson dressed shabbily” analogy and you will get my point.
