Most visitors do not read an entire page. They usually scan a page for information of interest to them and then move to the next. Try to reduce content redundancy and make sure that you get your point across before the user clicks out of your document . By being concise you also reduce the time your pages need to load over slow Internet connections. Optimize Content Optimizing the content of your pages is the process of reducing the complexity of them without compromising the information.
Optimization is directly related to bandwidth needs.
Therefore, you should put your navigation links at the top of the page so users can navigate through if they are not interested in the contents of the current page. For the same reason, you might want to move complex graphics and content to the bottom of the page whenever possible. Try to reduce the size of your images and use tables of images with descriptive names instead of image maps.
