A keyword cloud is more or less all the important keywords in a particular web site, close together. It can also be called the visual representation of the keywords used in a particular web site. In the case of a keyword that has been used more often in a web site, it is represented by larger fonts and is visually more prominent. Basically what this serves to be is a quick reference as to which keywords have been used in a particular web site, and you can also know the density of their use.

In order to work this key word cloud tool, you simply have to type in the URL of the web page you wish to analyze and let the tool do the rest. It will display a result in which all the frequently used keywords will be highlighted in larger fonts. The percentage of which each keyword has been used will then be displayed under that.

Keyword clouds that you may find online are usually a large group of keywords that are found together in the front of a web site. When a user goes and clicks on a particular keyword, he is then taken to a web page which is related to that specific keyword. Generally you would have to buy the rights to that keyword from that web site owner in order to have your web site pop up every time that keyword is clicked by one of his visitors. More or less this is a way to advertise your name through other people’s web sites, and gain more visitors and benefit from the additional traffic to your page. If the key word has not already been bought, then you are shown an application form which asks for your details and if you like you can buy the keyword and have your web site listed on it. So every time some one clicks on it, they will be directed to your web site.

So in other words a Keyword cloud can be called the visual depiction of any web site. Another factor to be considered is keyword density. Basically it is the number of times the keywords are repeated in the text of the web site. It is of great importance from a search engine optimization point of view that your main page has the correct balance of keywords in order for it to be ranked well in the search engine rankings. It is important to remember that the correct balance is vital. If you have too many keywords the crawlers will ignore them as they are programmed to think they do not make sense and if there are too few, the crawlers will not pick them up and you will not be brought up in the result. The Keyword cloud tool will give you the density of each keyword, in the correct percentage so you can adjust the text of your web page according to your need.
