The concept of designing your website like a funnel is very popular. There is a good reason for that. When you design your website the first and most important thing you should do is set an objective for it.
The website has to have a goal. Then stick to achieving that objective at all costs.
Focus on your content, not on unnecessary and distracting site gadgets.
Set desired outcomes and subdue your design to expressly achieve those desired outcomes.
Place clear and easy call to actions.
Provide incentives not only the user to act but also to return to your website.
