Just a few things to keep in mind before you manage to repeat the same mistakes everyone else makes, take a quick look at what follows.
Define Your Objectives:
The surest way to fail to reach your goals is never to define them. Many times web projects get started without any real clarity of purpose. This is a guarantee that you will spend too much time, too much money and never be happy with the result. One needs to be clear about targets and expectations if they are to be realized. This is particularly important when technical and non-technical are collaborating.
Remember to answer "The Question":
Later in our process document we will discuss this in more detail, but for now please keep in mind one simple fact, that people visit a web site to answer questions. This means that the web site should be organized in a way the caters to the visitor's questions, not your company's organizational structure. Too often web sites are built in a way that more resembles a given company's organizational chart, rather the than truly attempting to serve their existing and potential customers that visit it. Remember, they came there to answer a question, so be sure you know what it might be and have the answer ready. If a path to "their answer" is not obvious on the home page, that might be all they ever see of your site.
Avoid Graphics/Media Overload:
In today's job market, many so called "Web Designers" rely too heavily on WYSIWYG page layout tools and lack any real understanding of the tool's output. As a result, there are many sites on the web that suffer from a number of all to common problems:
How big is your screen?
Everybody involved in publishing web sites has either done it or seen it done at least once. You build a page layout, paying great attention to detail and get everything lined up just right. Then you show it to someone else, only to realize that your screen is bigger and size really does matter. Suddenly all that time you spent making everything fit just right has gone sideways because your monitor is the only one it fits on without scrolling to see the right side of the page.
Generally speaking, the personality type willing to take on this challenge of building a web site for the first time is also the same personality type that has a 21" monitor when most people have a 15". It is always a good practice to keep in mind the potential technical capabilities your audience may or may not have. Screen resolution is probably the most common issue where web designers fail to remember there are other monitors on earth besides their own, but there are a number of other issues as well. Connections speed, add ons like Flash, sound capabilities, JavaScript and style sheet support, just to name a few, all vary greatly depending on what the user is using to access your site.
State of THE Art vs. State of "their" Art
Before you start trying to embrace the newest latest technologies, consider your definition of success and how various technologies may or may not actually contribute to it. Just because you can does not mean you should. Developers as a group are by far the worst offenders here. A little common sense goes a long way.
