Websites are the new "Yellow Pages" combined with info brochures for business. They can attract business or turn people away. First impressions count so you need to look professional and clearly state what you offer! Don't make people guess as to what is your business and how they can be better off using your services or products.

Boldly state on your home page your business and what you offer. Then link to other pages that tell about products/services, industry, about the company, testimonials, ways to contact you, where you are, etc..

Your web site can be far more effective than an old "yellow pages" or newspaper advertisement. Because, not only can you have your "advertisement" but links to immediate additional information that is easily obtainable by the  prospective customer/client.

So not only do you need to have a web site, but you need to make it the best you can ... the first impression can bring you business or lose it.
