I have been designing web sites for a long time and I have seen plenty of sites that are hard to find and poorly done. This is a list of some of the things that can really detract from your content. Please let us know what you think about this list. Feel free to send us your additions to the list.
1. Using Frames
Frames can be very disruptive to users. They have some good points but I would not recommend them. Certain browsers and screen sizes aren't able to show frames properly and this makes frames unreliable. Remember, a designers goal is to make a site viewable to everyone.
2.To many extras
Some people tend to put too many java scripts and extras on their sites. Background music and js can be cool, but to much can be annoying. All these extras can also spike your load time chasing away people with slower connections.
3.Under Construction Signs
Good web pages are always under construction. These signs just give you an excuse not to have fully functioning content. Wait till you site is finished to place it on the web.
4.Missing Graphics
Make sure that all your graphic links are in place and that you don't use graphics with huge file sizes.
5.Outrageouse Fonts
Make sure that you don't use crazy fonts when you are trying to display information. These fonts can make it hard to read and annoy some users. Try to limit you use of crazy fonts.
6.To many animations
Make sure that you limit the amount of animations on your site. To many can be confusing and take away from your main content.
7.Orphan Pages
You need to try to make sure that all you pages give a clear indication of what they are and where they belong. All pages should also include a link to the index page.
8.Organization
Make sure that all you pages are presented in a sensible and organized manor
9.Outdated Information
Make sure that you keep your web pages up to date. Eliminate old material or move it to an archived page
10.Broken Links
Make sure to maintain your links and that you don't link to any dead web pages.
11. Bad Color Scheme
Make sure that your color schemes match and arent to hard to follow. Text colors should be easy to see over background colors.
