The same is true for a header or a footer that stays static while the content is scrollable. Some companies like this so that the corporate logo and contact information are always visible and easy to find. Using frames on a flash-enabled site is one way to get content indexed by search engines , as at present search engines can't spider the content in flash. As an argument against frames , the easy to update debate can be quashed by the use of server side includes which are probably easier to maintain than frames. And while having the company logo and contact information visible is important, this can be achieved by having pages which don't scroll too far down.
Frames have many usability issues, mainly in the form of the url being destroyed and orphaned pages.
This is where the textual body content that the main page contains goes. As with all search engine optimisation, make sure it is full of relevant keywords. The search engine will spider this information as it would a normal html page. This is useful for both the search engine to spider and for any user who finds the site on a search engine, as the page will be orphaned from its frameset. All rights reserved.
