The ultimate secret to create a Great Website
is to create a website with AIDA in mind:

Attention
The website needs to grab the viewer's attention as there are alot of websites that a surfer will see on a typical day. So, an attention grabbing website design is a must to get an extra highlight from other websites online! The design of the website plays an important role here.

Interest
The website needs to be of an interest to the visitor as that will make them excited to learn more. A good idea is to have a website that the surfer can interact with so that prospect would click on things you have for further information.

Desire
The website needs to have an attraction for the user to click on other links. Usually, points of interest, special offers, tips, FAQs, etc does the trick!

Action
An instruction on what you want the viewer to do: ENJOY THEIR VISIT!. There is no place for ambiguity, slowness, confusion, or frustration! Simplicity is what will sell you.

With these in mind, you are surely to have a killer website with high volume traffic. With AIDA in mind, it is ALWAYS possible to achieve above average!
