People tend to think that flashy websites work well when attracting visitors. Sure I'll go with that, but a visitor of that type probably has the mindset equivalent to a bird looking for shiny objects. Websites should be based on content. Shiny things are cool, but they distract from the actual content of the website, unless of course, your website is a collection of shininess [see ebaumsworld.com].
With this in mind, if one wanted their visitor to focus on the content, one would (I hope) strive to make their website visually pleasing, but subdued and lacking in flashiness. The HTML Hell Page describes things that one should not do if they want to attract visitors with IQs higher than that of a chipmunk. Here it is:

I hope you take these items into consideration so that the Internet will not be completely filled with painful-to-navigate web pages.
Thanks for reading. Have a nice day.
