The above link lets you come to a website of cocacola comapny. After see this website I have some opinions for a comercial website. Firstly, it is colorful (most of page is bright color). Secondly, there is not much text, the majority is exciting image of people who drink coca cola. Third, many flashes are used. In conclusion, a comercial website is colorful, funny, animatied and the image of people who use product is vigorous.
