Definition: buffer page

A Web page that is sent before, or with, the requested page in response to clicking a link. Typically, much smaller than a full page, buffer pages are used for a variety of purposes. Banner ads may generate a buffer page with questions in order to direct you to the appropriate page. A buffer page may disclose a legal notice or a warning; for example, that you must be at least 21 to continue. Several buffer pages may be used just to add metatags for search engine spiders in order to ensure the site gets into all the search engines.
