Hidden text is computer text that is displayed in such a way as to not be easily readable. Hidden text is most commonly achieved by setting the font color to be the same as the background color, rendering the text invisible unless the user highlights it. An example of some hidden text follows on the next line:

This text is hidden because the font color was changed to white.

(To reveal the text, one merely needs to disable style sheets in their browser, use a text-only browser, or highlight it with one's cursor.)

Hidden text can serve several purposes. Often web sites use it to disguise spoilers for readers who do not wish to read that text. Hidden text can also be used to hide data from users less Internet-savvy or who are not familiar with a particular website. An example of this practice is to display an FTP password in hidden text to reduce the number of users who are able to access downloads and thereby save bandwidth.

It is also used by websites as a spamdexing technique to fill a page with keywords that a search engine will recognize but are not visible to a visitor. However, Google has taken steps to prevent this by parsing the colour of text as it indexes it and checking to see if it is similar to or the same colour as the background, giving those pages much lower rankings.

Compare with metadata, which is usually also hidden, but is used for different purposes.

How can I find out if there is hidden text in a document?
Q. I'm using microsoft office word 2007 and microsoft works. I know there is (or was) a way to determine if there is hidden text in documents that you have cut and pasted to either of these programs. Can anyone tell me how? I'm drawing a blank or not clicking on the right set of buttons etc.

One of the very first things you'll read in any introduction to SEO post is that you shouldn't use . hidden text. on your site. While this sounds simple, you could be violating Google's webmaster guidelines without knowing it.
