Good websites

I have been researching what makes a good website (preferably one that promotes or advertises something.) After a lot of browsing and mind-map making, I have come up with this report:

After checking out different websites, I have come to the conclusion that a good website needs to be clear, precise and informative. If the website promotes something, it needs to have photographs, a regularly updated news section and contact details of the company or person. If it is advertising, it should have persuasive language and bright, attractive colours. It might also be a good idea to have an informative video to tell the public about the product or company.

Naturally, I will have more information on the project as it develops. I will not actually be making the web page, just researching how to create a good one.
