The Funders Online Guidelines provide an overview of some of the major issues you should consider and pay attention to when developing your website.
Content can be pure information, services or a combination of the two.
To begin with, you can simply publish existing materials, written for print, to your website. However, in the long run, you should focus on developing or editing content specifically for the web. When developing your content, keep in mind that people don't read the same way on the web as they do books - rather, they scan the text, picking out individual words or expressions. Avoid jargon or highly specialised language, unless you are targeting a professional audience. A simple and logical architecture is absolutely essential for the effectiveness of your site - information should be easy to find and access, ideally just two or three clicks away.
