What is hidden text? And will it boost my ranking?
Hidden text is sometimes put into the HTML so that a the web bots will think that the site has a lot of good content. The text is usually a jumble of keywords that cannot be seen by the user but are recognized by the search engine. It is sometimes called search spam because it is unusable by anyone but the search engines. It will boost your website rating temporarily until the search engine realizes it is spam and permanently bans the site from the search engine. Not a good risk to take and I do not recommend it at all.
