Put your e-mail address, phone if necessary, in a prominent location on your site. Use links to other sites that are relevant to yours. You don't have to reinvent the wheel. There is a lot of information on the web that may relate and can be helpful to visitors to your site. Include the webmaster's e-mail address on the contact page.
Viewers can report missing links or other problems.
Nothing is more frustrating than links that don't work. Make sure your site is accessible to everyone regardless of the browser they are using. Keep this in mind when including graphics and some of the bells and whistles you would like to use. Do not forget that your web site can be viewed by anyone, anywhere. If you are trying to reach a global audience make sure your graphics can be translated and understood internationally.
