Hidden Pages
WebDynamic™ Web Glossary
When Google explores the Web, googlebot creates a copy of each examined page and stores it in a memory hiding place, which makes it possible to consult this copy constantly and in particular if the original page (or Internet) would be inaccessible. When you click on the bond "Copies hidden" of a Web page, Google posts this one in the state where it was during its most recent indexing. In addition, the hidden contents are that on which Google is based to determine if a page is relevant for your requests.
