For implementing search engine spiders. A common trick used by search 
engine optimisation tricksters is to include a bunch of keywords in the 
body of the document that are invisible to the naked eye. There are a 
number of ways of doing this using CSS - you can set the text to the 
same or a very similar colour to the background, or you can hide the 
text using a CSS command such as display: none, visibility: hidden or 
even text-indent: -1000em.
