Hidden Text

This is text that can not be seen in a normal browser. Some websites use hidden text to trick search engine spiders. Hidden text can contain high density keywords that make no sense to a normal person but can make search engines believe a site is about a certain subject. Hidden text can be implemented in many ways: beneath images, in white on a white background, within certain code-tags or just in a very, very, small font. It is therefore hard for search engine spiders to detect this kind of fraud, but they are becoming increasingly better at it.
