Generally, this list is displayed in alphabetical order; the most important words are assigned a larger font. It is therefore a weighted list. The most important words are the keywords that appear most often in content.

The Tag Cloud is a new element in the interface of a web site and provides an additional and powerful search and navigation tool.

Another way to display the Tag Cloud, widely used in SevenDaysWeb, is to indicate the number of contents next to the keyword instead of playing on the font size. This makes the list neater and less noisy.
