,,Google supports frames to the extent that it can. Frames can cause problems for search engines because they don’t correspond to the conceptual model of the web. In this model, one page displays only one URL. Pages that use frames display several URLs (one for each frame) within a single page. If Google determines that a user’s query matches the page as a whole, it will return the entire frame set. However, if the user’s query matches an individual frame within the larger frame set, Google returns only the relevant frame. In this case, the entire frame set of the page will not appear.
If you’re concerned with how your site appears in the Google search results, please read “Search Engines and Frames” at http://www.searchenginewatch.com/webmasters/frames.html
This document describes the use of the “NoFrames” tag to provide alternate content. If you use wording such as “This site requires the use of frames,” or “Upgrade your browser,” instead of providing alternate content on your site, then you’ll exclude both search engines and individuals who’ve disabled frames on their browsers. For example, audio web browsers, such as those used in automobiles and by the visually impaired, typically do not support frames.
