What Is Invisible Text?

Because search engines easily detect regular keyword stuffing, some spammers have supplanted regular keyword stuffing with the more subtle technique of using invisible text. Invisible text is the method of inserting hidden, usually keyword-heavy, text in the body of a Web page by making the text the same color as the page's background, rendering the text invisible to the user, unless the text is highlighted. Albeit less obvious than regular keyword stuffing, invisible text is still perceived as spamming and the technique therefore is not recommended as a means to improve search engine rankings.
