It is pointless for me to say, having a website to promote your business is essential nowadays. Due to the fact that nearly all of your potential costumers will come across you throughout the internet and often they will contact you through the website.
Furthermore the great thing about the internet is that it can reach the whole world, and not just your neighbourhood. Your website is your shop window and it is open 24/7.
Therefore it needs to be eye catching and transmit your message in a few seconds (did you know that you only having maximum 8 second to attract a customer whose looking at your website?) otherwise you will loose them and they will continue surfing until there eye catch something they like.
For that reason it needs to have enough content that explains your message and what you can provide but on the other hand not too much information which they can’t understand or find useful. It also needs to load fast, be reliable and look professional. The impression your website should give is that your professional and you know what you want to sell.
