Design is important - that means if you can get your information across without 20k fancy graphics, don't worry about the graphics. You might only get 3 or 4 mouse clicks to deliver what your reader wants. If you fail, he or she goes elsewhere. If you are selling a product or service, this should be obvious from your Front Page - like a Buy Button or Link. If you sell more than 2 or 3 items, an Index to the products is essential.
Readers can then rapidly select what they want.
Provide relevant links, descriptions or reviews wherever possible. You need to select reputable programs - and top products or services. Regular updates - both via your web site and newsletters. Web Site Promotion - people need to know your site exists. You have to spend money to make money.
