Sites can differ in many ways but perhaps the most obvious is size, which will vary depending on your target audience.

In their simplest form, we produce web sites of 3 or 4 pages, containing an overview of your company and it's products. This is an advertisement mainly aimed at letting people know that you are 'out there' and introduce them to your products and services. This is similar to an advertisement that you may place in a newspaper or magazine.

The above concept of a simple static site may be extended to a greater number of pages, listing product ranges and as much technical detail as you feel appropriate - possibly including prices. Such an advertisement could be informative enough for a prospective customer to select the particular item they wish to purchase, and then contact you for final details and to make the purchase.

Ultimately you may wish to operate a full e-commerce site with detailed price lists containing descriptions and pictures of individual items and a search mechanism to select the most appropriate for ordering. Tuned for rapid update, price list could changed monthly, weekly or even daily. Such a system would be able to generate orders over the web directly.
